bignerd第10章 UINavigationController
1.rely on each other
    drill-down interface.向下获取数据

2.UINavigationController 保持了所有screens的堆栈

    root view controler: UIViewController是堆栈的最底层

    when a UIViewController is pushed onto the stack,its view slides onto the screen from the right

                    |navigateBar ->
    UIViewController|                        |rootViewController(ListViewController)
                    |viewControllers(array) |
                    |                        |appViewController(DetailViewController)

    属性 topViewController获取最顶端的视图控制器

    UINavigationController是 UIViewController的子类，也有view属性，
    view 一般都有两个子view: UINavigationBar 和 the view of topViewController

3.tip
    when writing IOS applications, it is important to treat each UIViewController as its own little world.

4.几个要点：
    控制器之间传递数据
        重写比如BNRItem *item的setter，
        在viewDidAppear之类的函数中操作显示
    手动push viewController

//////几个章节做概览即可。然后去做实际的项目练习，不清楚的再回来翻/////////
11章Camera
    UIImageView:
                    aspect fit  contentMode
    UIToolbar

    UIImagePickerController


 设定类型
    image picker's source type  UIImagePickerControllerSourceTypeCamera,PhotoLibrary,PhotosAlbum.类型
          使用之前先判定 isSourceTypeAvailable:
设定delegata
    头文件声明 <UINavigationControllerDelegate,UIImagePickerControllerDelegate>
        image picker's delegate = self;

        成功选择图片：
            imagePickerController:didFinishPickingMediaWithInfo:
        取消选择
            imagePickerControllerDidCancel
          
        presenting the image picker modally
            - (IBAction)takePicture:(id)sender
                {
                    UIImagePickerController *imagePicker =
                            [[UIImagePickerController alloc] init];

                    // If the device has a camera, take a picture, otherwise,
                    // just pick from photo library
                    if ([UIImagePickerController
                            isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
                        imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
                    } else {
                        imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
                    }

                    imagePicker.delegate = self;
                    [self presentViewController:imagePicker animated:YES completion:nil];
                }
    --------------------------------
    获取图片saving image
        - (void)imagePickerController:(UIImagePickerController *)picker
        didFinishPickingMediaWithInfo:(NSDictionary *)info
        {
            // Get picked image from info dictionary
            UIImage *image = info[UIImagePickerControllerOriginalImage];

            // Put that image onto the screen in our image view
            self.imageView.image = image;

            // Take image picker off the screen -
            // you must call this dismiss method
            [self dismissViewControllerAnimated:YES completion:nil];
        }

注意：按上面那种方式，当你保存很多图片时，很占内存，甚至应用被强行关闭。
       用BNRImageStore来保存图片，当受到内存不足的警告时清理不需要的。

    NSDictionary

    NSUUID  创建一个唯一的 码？

    #pragma mark

    隐藏键盘：
        -(BOOL)textFieldShouldReture:(UITextField *)textField
        {
            [textField resignFirstResponder];
            return YES;
        }
        BNRDetailViewController.xib中，选择view，更改类为UIControl，将view链接出一个单击action，
            [self.view endEditing:YES];

    Recording Video
        判断是否支持录像
         UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
            NSArray *availableTypes = [UIImagePickerController
                availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
            ipc.mediaTypes = availableTypes;
            ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
            ipc.delegate = self;

        委托
        - (void)imagePickerController:(UIImagePickerController *)picker
        didFinishPickingMediaWithInfo:(NSDictionary *)info
        {
            // 保存在影片在磁盘中的地址
            NSURL *mediaURL = info[UIImagePickerControllerMediaURL];
            if (mediaURL) {

            // Make sure this device supports videos in its photo album
            if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum([mediaURL path])) {

                // Save the video to the photos album
                UISaveVideoAtPathToSavedPhotosAlbum([mediaURL path], nil, nil, nil);

                // Remove the video from the temporary directory
                [[NSFileManager defaultManager] removeItemAtPath:[mediaURL path]
                                                           error:nil];
            }
        }
        }
注意：限制用户只选择拍照或者只录像
    两者都可选：pass the return value from availableMediaTypesForSourceType:
    拍照的话：保持mediaTypes为默认的即可
    只要录像：First, you must make sure the device supports video, and then you must set the mediaTypes property to an array containing only the identifier for video.
            NSArray *availableTypes = [UIImagePickerController
        availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
        if ([availableTypes containsObject:(__bridge NSString *)kUTTypeMovie]) {
            [ipc setMediaTypes:@[(__bridge NSString *)kUTTypeMovie]];
        }

12章 Touch Events and UIResponder
    触摸事件touch events，手势 gestures， 调试 debugging application

    UIView 继承UIResponder，所以可以重写以下四个方法:
        touchBegan:(NSSet *)touches withEvent:
        touchMoved:withEvent:
        touchEnded:withEvent:
        touchCancel:withEvent:

        touche中有个UITouch的对象，包含了触碰的位置等信息
        你不需要保存UITouch的对象，因为在事件中你可以访问得到。
        当手指滑出初始触碰到视图，会受到touchMoved和touchEnded
～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～
// 重写几个touch事件，获取location。
// setNeedDisplay,系统自动调用drawRect,
// 如何绘制、设置颜色、stoke等。

            #import "BNRDrawView.h"
            #import "BNRLine.h"

-----------------------------------------------------------------------
    多点触控。
        默认情况下一个view只能接受一个finger的touch: 一个手指触发了touchBegan,但是没有ended。则view会忽略其他触碰

     self.multipleTouchEnabled = YES;
     touchCancelled发生在系统事件，比如电话来了～，一般这时候会把当前线段都移除掉

     保存多个数据

        @end





    Responder chain
        每个responder有一个nextResponder属性，构成chain。 rootView: window's nextResponder is UIApplication
'
    UIControl:can set targets and actions
        the superclass of UIButton,UISlider...
        [rButton addTarget:tempController action:@selector(resetTemperature:) forControlEvents:UIControlEventTouchUpInSide | UIControlEventTouchUpOutSide]

        then you can send event:
        [self sendActionsForControlEvents:UIControlEventTouchUpInSide]

        消息不是直接发送给目标view，而是通过UIApplication来找到target
        -----------重写UIResponder---------------------
        - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
        {
            // Reference to the touch that is ending
            UITouch *touch = [touches anyObject];

            // Location of that point in this control's coordinate system
            CGPoint touchLocation = [touch locationInView:self];

            // Is that point still in my viewing bounds?
            if (CGRectContainsPoint(self.bounds, touchLocation))
            {
                // Send out action messages to all targets registered for this event!
                [self sendActionsForControlEvents:UIControlEventTouchUpInside];

                // The touch ended outside the bounds, different control event
                [self sendActionsForControlEvents:UIControlEventTouchUpOutside];
            }

    UILongPressGestureRecognizer
    UIPanGestureRecognizer and Simultaneous Recognizers

    UIMenuController and UIResponderStajdardEditAction

-----------------------------------------------------------------------------------------------------------------------------------------

Chapter 13 UIGestureRecognizer and UIMenuController.

1. gesture like pinch or swipe

2.you don't instantiate UIGestureRecognizer, system has some subclass that u can use for the particular gesture. the action message like:

- (void) action:(UIGestureRecognizer *)gestureRecognizer;

** when recognizing a gesture,the gesture recognizer intercepts the touch destined for the view.so the like touchBegan: may not receive. the flow:

    UIApplication --touch event--> UIWindow --touch event--> UIGestureRecognizer -- recognized gesture(yes/no)--> if yes: send action: to view; if not,send touchesBegan:withEvent: to the view.

*********************

UITapGestureRecognizer: double tap screen and clear the lines:

-(instancetype)initWithFrame:(CGRect)r

{

//......

UITapGestureRecognizer *doubleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];

doubleTapRecognizer.numberOfTapsRequired = 2;

[self addGestureRecognizer:doubleTapRecognizer];

return self;

}

-(void)doubleTap:(UIGestureRecognizer *)gr

{

// for a double tap, u don't need information from gr

[self.linesInProgress removeAllObjects];

[self.finishedLines removeAllObjects];

[self setNeedsDisplay];

}

the flow: 1.send touchesBegan:; 2.recognized the double tap, send doubleTap: 3.send touchedCancelled:.

*** so if u don't want the 1 happens,set like:

doubleTapRecognizer.delaysTouchesBegan = YES;

----------------multiple gesture recognizers----------

like: if u add a tap and double tap to a view,when u double the view,it will send to tap first and then send to doubleTap. So, the truth is : if u double tap the screen,the tap may not what u want to trigger,so set like:

[tapRecognizer requireGestureRecognizerToFail:doubleTapRecognizer];

means during the double tap happen, the one tap will force to fail.

***** one tap to choose a line*******

when select a line,a menu appear right at the tap point.

UIMenuController, 

UIMenuItem (the list that controller has) each item has a title and action. the action message is send to the first responder of the window,so there is not the gesture,view 's business///

***There is only one UIMenuController per Application, u can fill it with menu items to it, and give it a rectangle to present form,and set it to be visible.******

do like:

-(void) tap:(UIGestureRecognizer *)gr

{

// get the tap location

CGPoint point = [gr locationInView:self];

self.selectedLine = [self lineAtPoint:point];

if(self.selectedLine){

//!!! make ourselves the target of menu item

// action messages

[self becomeFirstResponder];

// grab the msnu controller

UIMenuController *menu = [UIMenuController sharedMenuController];

// create delete item

UIMenuItem *deleteItem = [[UIMenuItem alloc] initWithTitle:@"Delete" action:@selector(deleteLine:)];

menu.menuItems = @[deleteItem];

// show it

[menu setTargetRect:CGRectMake(point.x,point.y,2,2) inView:self];

[menu setMenuVisible:YES animated:YES];

}else{

// hide menu controller

[[UIMenuController sharedMenuController] setMenuVisible:NO animated:YES];

}

[self setNeedsDisplay];

}

*****if u have a custom class needs to become the first responder,u must override canBecomeFirstResponder:

-(BOOL)canBecomeFirstResponder

{

return YES;

}

*** what u do below, when u tap a line, the menu is not shown at all. the reason:

1.becomeFirstResponder       [done]

2.implemented each item's selector  [not yet]

so:

-(void) deleteLine:(BNRLine *) line

{

[self.finishedLines removeObject:self.selectedLine];

[self setNeedsDisplay];

}

 ======================================

UILongPressGestureRecognizer

***when u hold down on a line (a long press),u selected the line and then drag it around by dragging you finger (pan)

as add other gesture add the long press gesture.

notice that need more than 0.5s,u can change it by set minimumPressDuration.

%%the below gesture is the simple gesture: by the time it is recognized,the gesture is over, and the message has been delivered . 

%% long press is occurs over time and is defined by three separate events.

UIGestureRecognizerStatePossible,   [press a while]

UIGestureRecgonizerStateBegan,    [like at lease 0.5]

UIGestureRecognizerStateEnded. [remove finger]

the state property

*************

-(void)longPress:(UIGestureRecognizer *)rg

{

if(rg.state == UIGestureRecognizerStateBegan){

CGPoint *point = [rg locationInView:self];

self.selectedLine = [self lineAtPoint:point];

if(self.selectedLine){

self.linesInProgress removeAllObjects];

}

}else if(rg.state == UIGestureRecognizerStateEnded){

self.selectedLine = nil;

}

[self setNeedsDisplay];

}

------------UIPanGestureRecognizer Simultaneous Recognizer---------------

pan: move the line with finger around the screen

** normally ,a gesture recognizer does not share the touches.just like eat the touch,and no other recognizer get a chance to handle it. But this is bad ,u need the long press and panning.

do like:

@interface BNRDrawView () <UIGestureRecognizerDelegate>

@property (nonatomic,strong) UIPanGestureRecognizer *moveRecognizer;

// other code ....

@end

// code in implementation

self.moveRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(moveLine:) ];

self.moveRecognizer.delegate = self;

self.moveRecognizer.cancelsTouchesInView = NO;

[self addGestureRecognizer:self.moveRecognizer];

*****u just need to implementation one method about UIGestureRecognizerDelegate protocol,:

gestureRecognizer:shouldRecognizerSimultaneouslyWithGestureRecognizer:

&&when a recognizer hold the gesture,at the same time ,another recognizer recognized the gesture,so, it will send the message.

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizerShouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)other

{

if(gestureRecognizer == self.moveRecognizer){

return YES;

}

return NO;

}

-(void)moveLine:(UIPanGestureRecognizer *)gr

{

if(!self.selectedLine){

return;

}

if(gr.state == UIGestureRecognizerStateChanged){

CGPoint translation = [gr translationInView:self]

CGPoint begin = self.selectedLine.begin;

CGPoint end = self.selectedLine.end;

begin.x += translation.x;

begin.y += translation.y;

end.x += translation.x;

end.y += translation.y;

self.selectedLine.begin = begin;

self.selectedLine.end = end;

[self setNeedsDisplay];

//************]

[gr setTranslation:CGPointZero inView:self];

}

}

存档 
1.Archiving，永久存储数据。
Archiving:记录并存储属性
Unarchiving:从数据中重新重新创建对象。


实现NSCoding协议，实现两个方法 encodeWithCoder:, initWithCoder:


    - (void)encodeWithCoder:(NSCoder *)aCoder
{
   [aCoder encodeObject:self.itemName forKey:@"itemName"];
   [aCoder encodeObject:self.serialNumber forKey:@"serialNumber"];
   [aCoder encodeObject:self.dateCreated forKey:@"dateCreated"];
   [aCoder encodeObject:self.itemKey forKey:@"itemKey"];


   [aCoder encodeInt:self.valueInDollars forKey:@"valueInDollars"];
}


-(instancetype) initWithCoder:(NSCoder *)aDecoder
{
self = [super init];
if(self){
_itemName = [aDecoder decodeObjectForKey:@"itemName"];
}
return self;
}


2.应用沙箱， Application sandbox
程序的数据，缓存等。 不能访问其他应用的沙箱


！！！！！！！！！存储路径！！！！！！！！！！
-(NSString *)itemArchivePath
{
NSArray *documentDirectories = 
NSSearchPathForDirectoriesInDomain(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentDirectiry = [documentDirectories firstObject];
return [documentDirectories stringByAppendingPathComponent:@"items.archive"];


}


**************上面的到了存储的路径，以及药存储的模型数据。那什么时候出发存储已经什么时候加载数据呢？＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊


1.存储： 
使用NSKeyedArchiver when application exits.


eg. BNRItem
-(BOOL) saveChanges
{
NSString *path = [self itemArchivePath];
return [NSKeyedArchiver archiveRootObject:self.privateItems];
}


!archiveRootObject:toFile: 工作流程：
1.创建NSKeyedArchiver 对象
2.privateItems发送消息 encodeWithCoder: 并且把 NSKeyedArchiver的对象作为参数。
3.privateItems发送每个其中的字对象  encodeWithCoder,并且传入 NSKeyedArchiver
4.NSKeyedArchiver 写数据到系统文件夹中




当按下home键，applicationDidEnterBackground:会发送到applicationDelegate中，你可以在其中调用saveChanges
它会存在系统文件夹下，一个document文件夹中 item.archive


加载！！：
-(instancetype)initPrivate
{
self = [super init];
if(self){
NSString *path = [self itemArchivePath];
_privateItems = [NSKeyedUnarchiver unarchiveObjectWithFile:path];
if(!_privateItems){
_privateItems = [[NSMutableArray alloc] init];
}
}
return self;
}
