本人用过的三方库

1、使用HMSegmentedControl实现分段控件

HMSegmentedControl 是 UISegmentedControl 的替代品，模仿了 Google Currents 使用的效果。

HMSegmentedControl

A drop-in replacement for UISegmentedControl mimicking the style of the segmented control used in Google Currents and various other Google products.

Features

• Supports both text and images
• Font and all colors are customizable
• Supports selection indicator both on top and bottom
• Supports blocks
• Works with ARC and iOS >= 5

Installation

CocoaPods

The easiest way of installing HMSegmentedControl is via CocoaPods.

pod 'HMSegmentedControl', '~> 1.1.0'

Cocoa-whaa?

If you haven't heard about CocoaPods (seriously, where were you?!), it's a dependency manager for Xcode projects that provides very simple installation of libraries. Here's how to get started.

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods$ pod setup

Change to the directory of your Xcode project, and Create and Edit your Podfile and add HMSegmentedControl:

$ cd /path/to/MyProject$ touch Podfile$ edit Podfileplatform :ios, '5.0' pod 'HMSegmentedControl', '~> 1.2.0'

Install into your project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file)

$ open MyProject.xcworkspace

Old-fashioned way

• Add HMSegmentedControl.h and HMSegmentedControl.m to your project.
• Add QuartzCore.framework to your linked frameworks.
• #import "HMSegmentedControl.h" where you want to add the control.

Usage

The code below will create a segmented control with the default looks:

[objc] view plain copy

1. HMSegmentedControl *segmented = [[HMSegmentedControl alloc] initWithSectionTitles:@[@"已收公告",@"已发公告"]];  
2. segmented.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;  
3. segmented.frame = CGRectMake(self.view.bounds.size.width/2-100, 4, 200, 40);  
4. segmented.backgroundColor = [UIColor clearColor];  
5. segmented.selectionIndicatorHeight = 3.0f;  
6. segmented.font = [UIFont fontWithName:@"STHeitiSC-Light" size:19.0f];  
7. segmented.textColor = WHRGB(255, 175, 185);  
8. segmented.selectedTextColor = [UIColor whiteColor];  
9. segmented.selectionIndicatorColor = [UIColor whiteColor];  
10. segmented.selectionStyle = HMSegmentedControlSelectionStyleFullWidthStripe;  
11. segmented.selectionIndicatorLocation = HMSegmentedControlSelectionIndicatorLocationDown;  
12. [segmented addTarget:self action:@selector(segmentedControlChangedValue:) forControlEvents:UIControlEventValueChanged];  
13. self.segmentedControl = segmented;  
14. [self.navigationController.navigationBar addSubview:segmented];  

Included is a demo project showing how to fully customise the control.

重要例子2：

////  ViewController.m//  分段控件三方库////点击每个不同的segument，转到那个按钮相应的view#import "ViewController.h"#import "HMSegmentedControl.h"CGFloat segmengHight = 35;#define  YBSCREEN    [UIScreen mainScreen].bounds.size@interface ViewController ()<UIScrollViewDelegate>@property (nonatomic,strong) UIScrollView *scrollView;@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib.     CGRect r = [ UIScreen mainScreen ].bounds;    HMSegmentedControl *segmented = [[HMSegmentedControl alloc] initWithSectionTitles:@[@"已收公告",@"已发公告",@"要发公告"]];    segmented.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;    segmented.frame = CGRectMake(0, 66, self.view.frame.size.width, 35);    segmented.backgroundColor = [UIColor yellowColor];    segmented.selectionIndicatorHeight = 3.0f;    segmented.selectionIndicatorColor = [UIColor whiteColor];    segmented.selectionStyle = HMSegmentedControlSelectionStyleFullWidthStripe;    segmented.selectionIndicatorLocation = HMSegmentedControlSelectionIndicatorLocationDown;    __weak typeof(self) weakSelf = self;    self.scrollView.backgroundColor = [UIColor redColor];    //当点击segment，就是点击其他的按钮时，就会通过下方的block，在不同的按钮里实现不同的方法    [segmented setIndexChangeBlock:^(NSInteger index) {        //这个方法是scrollView在点击segment按钮后所显示的页面        [weakSelf.scrollView scrollRectToVisible:CGRectMake(self.view.frame.size.width * index, 0, self.view.frame.size.width, 200) animated:YES];    }];        [self.view addSubview:segmented];            self.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 66 + segmengHight, YBSCREEN.width, r.size.height - 66 - segmengHight)];    self.scrollView.backgroundColor = [UIColor colorWithRed:0.7 green:0.7 blue:0.7 alpha:1];    self.scrollView.pagingEnabled = YES;    self.scrollView.showsHorizontalScrollIndicator = NO;    self.scrollView.contentSize = CGSizeMake(YBSCREEN.width*3, 640 - 66 - segmengHight);    self.scrollView.delegate = self;    [self.scrollView scrollRectToVisible:CGRectMake(0, 0, YBSCREEN.width, _scrollView.frame.size.height) animated:NO];//这句可加可不加    [self.view addSubview:self.scrollView];        for (int i= 0; i<3; i++) {        UIView *view = [[UIView alloc]initWithFrame:CGRectMake(i*YBSCREEN.width, 0, YBSCREEN.width, r.size.height - 66 - segmengHight)];        if (i == 1) {            view.backgroundColor = [UIColor redColor];        }else if (i == 2)        {            view.backgroundColor = [UIColor yellowColor];        }else        {            view.backgroundColor = [UIColor blueColor];        }        [self.scrollView addSubview:view];    }}@end

2、SSZipArchive使用详解

下载SSZipArchive，点击我。或者自己在这里下载。

SSZipArchive功能：

1. 解压zip文件
2. 解压密码保护的zip文件
3. 创建zip文件
4. 追加到zip文件
5. 压缩文件
6. 使用一个名字来压缩NSData

使用前：

1. 把SSZipArchive文件添加到项目中
2. 在target中添加libz.dylib

使用方法：

[objc] view plain copy

 

1. // 解压  
2. NSString *zipPath = @"被解压的文件路径";  
3. NSString *destinationPath = @"解压到的目录";  
4. [SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];  
5.   
6. // 压缩  
7. NSString *zippedPath = @"压缩文件路径";  
8. NSArray *inputPaths = [NSArray arrayWithObjects:  
9.                        [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],  
10.                        [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]  
11.                        nil nil];  
12. [SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];  

2、

SWTableViewCell——一个和iOS 7的系统Mail类似，使用起来简单的UITableViewCell子类

• 关键字：系统Mail，iOS7,
• 代码类库：视图动画(ViewAnimation)
• GitHub链接：https://github.com/CEWendel/SWTableViewCell

一个使用起来很简单的UITableViewCell子类，可以通过左右滑动调出view，view上有工具按钮（和iOS 7的系统Mail类似）。

 

功能
右边的工具按钮
用户向左滑动可以调出工具按钮，在Table View Cell的右边显示。这种和iOS的系统Mail和Reminders类似。

 


左边的工具按钮
如果用户向右边滑动也可以调出工具按钮，在Table View Cell的左边显示。

 


特点
动态的工具按钮，大小可以调整。如果在一个cell中需要增加更多的按钮，那么其他的按钮会自动缩小提供空间。

按钮的名字和颜色可以自己调整。

在iOS6.1以上系统，包括iOS 7中测试通过。


用法
在tableView:cellForRowAtIndexPath:方法中创建一个SWTableView cell，使用NSMutableArray+SWUtilityButtons 类给它添加任意数量的工具按钮。

    staticNSString *cellIdentifier = @"Cell";

 

    SWTableViewCell *cell = (SWTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];

 

    if(cell == nil) {

        NSMutableArray*leftUtilityButtons = [NSMutableArraynew];

        NSMutableArray*rightUtilityButtons = [NSMutableArraynew];

 

        [leftUtilityButtons addUtilityButtonWithColor:[UIColor colorWithRed:0.07 green:0.75f blue:0.16f alpha:1.0] icon:[UIImage imageNamed:@"check.png"]];

        [leftUtilityButtons addUtilityButtonWithColor:[UIColor colorWithRed:1.0f green:1.0f blue:0.35f alpha:1.0] icon:[UIImage imageNamed:@"clock.png"]];

        [rightUtilityButtons addUtilityButtonWithColor:[UIColor colorWithRed:0.78f green:0.78f blue:0.8f alpha:1.0] title:@"More"];

        [rightUtilityButtons addUtilityButtonWithColor:[UIColor colorWithRed:1.0f green:0.231f blue:0.188 alpha:1.0f] title:@"Delete"];

 

        cell = [[SWTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier height:_tableView.rowHeight leftUtilityButtons:leftUtilityButtons rightUtilityButtons:rightUtilityButtons];

        cell.delegate = self;

    }

 

    NSDate*dateObject = _testArray[indexPath.row];

    cell.textLabel.text = [dateObject description];

    cell.detailTextLabel.text = @"Some detail text";

 

returncell;

}

Delegate

开发者可以使用SWTableViewCellDelegate来了解用户点击了哪个按钮。有两种方法：

?

- (void)swippableTableViewCell:(SWTableViewCell *)cell didTriggerLeftUtilityButtonWithIndex:(NSInteger)index;

- (void)swippableTableViewCell:(SWTableViewCell *)cell didTriggerRightUtilityButtonWithIndex:(NSInteger)index;

index指示用户点击了哪个按钮。

#pragma mark - SWTableViewDelegate

 

- (void)swippableTableViewCell:(SWTableViewCell *)cell didTriggerLeftUtilityButtonWithIndex:(NSInteger)index {

    switch(index) {

        case0:

            NSLog(@"check button was pressed");

            break;

        case1:

            NSLog(@"clock button was pressed");

            break;

        case2:

            NSLog(@"cross button was pressed");

            break;

        case3:

            NSLog(@"list button was pressed");

        default:

            break;

    }

}

 

- (void)swippableTableViewCell:(SWTableViewCell *)cell didTriggerRightUtilityButtonWithIndex:(NSInteger)index {

    switch(index) {

        case0:

            NSLog(@"More button was pressed");

            break;

        case1:

        {

            // Delete button was pressed

            NSIndexPath*cellIndexPath = [self.tableView indexPathForCell:cell];

 

            [_testArray removeObjectAtIndex:cellIndexPath.row];

            [self.tableView deleteRowsAtIndexPaths:@[cellIndexPath] withRowAnimation:UITableViewRowAnimationAutomatic];

            break;

        }

        default:

            break;

    }

}

提示
定制UITableViewCell内容

• 不要使用Storyboards来创建你的定制的UItableViewCell内容。只需要简单的在- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath中增加view到cell的contentview。
• 获仍然可以取cell object的view或者管理预定义的内容。所以说如果你想要改变cell的imageView 或者是backgroundView，SWTableViewCell，仍然可以按照你希望的变化进行改变。
• 不要在cell中使用accessory view，因为他们的层级处于contentView之上，如果cell消失了的话，他们不会随之消失 。

Seperator Insets

如果在iOS 7中你有一个左边的工具按钮，我推荐你改变TableView 的seperatorInsect，这样可以让seperator扩展到屏幕的长度。

tableView.separatorInset = UIEdgeInsetsMake(0, 0, 0, 0);

我贼程序中用到的是通过自己的cell继承与SWTableViewCell,实现左滑。
