xcode6.1开发环境下开发视图间切换程序

xcode6.1开发环境下开发视图间切换程序

1、  新建一个空项目

因为xcode6.1没有空项目，所以先从Single View Application 模板新建ios项目。

Product Name输入Switch，完成。下面开始删除一些文件，并改变一些配置。

 

2、  删除视图和界面文件

删除Main.storyboard和LaunchScreen.xib ，完成后在info.plist文件中也需要删除对应的配置，通过点击减号即可。

删除默认的视图控制器文件ViewController.h ViewController.m；

 

 

3、  创建视图控制器

下一步输入控制器类名称；

完成后生成两个文件：SwitchViewController.h和SwitchViewController.m;

按照同样的步骤，新建BlueViewController.m和YellowViewController.m及对应的.h文件。

4、  创建视图文件

通过新建文件，选择User Interface类别的View；分别命名为SwitchView、BlueView、YellowView；

 

5、  添加视图控制器

把视图默认的类NSObject修改成对应的控制器类；

 

6、  关联视图与控制器

 

同样方式给其他两个视图添加控制器；

 

 

7、  修改应用程序委托

#import <UIKit/UIKit.h>

@classSwitchViewController;

@interfaceAppDelegate :UIResponder <UIApplicationDelegate>

@property (strong,nonatomic) UIWindow *window;

@property (strong,nonatomic) SwitchViewController *switchViewController;

@end

 

AppDelegate.m文件的didFinishLaunchingWithOptions方法修改如下：

 

#import "AppDelegate.h"

#import "SwitchViewController.h"

@implementationAppDelegate

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {

self.window = [[UIWindowalloc]initWithFrame:[[UIScreenmainScreen]bounds]];

self.switchViewController = [[SwitchViewControlleralloc]initWithNibName:@"SwitchView"bundle:nil];

    UIView *switchView =self.switchViewController.view;

    CGRect switchViewFrame = switchView.frame;

    switchViewFrame.origin.y += [UIApplicationsharedApplication].statusBarFrame.size.height;

    switchView.frame = switchViewFrame;

    self.window.rootViewController = self.switchViewController;

   

    self.window.backgroundColor = [UIColorgreenColor];

    [self.windowmakeKeyAndVisible];

   

    returnYES;

}

8、  运行测试，查看结果

绿色界面是switchView的背景颜色，并添加了Toolbar到底部。

 

9、  主控制器中申明其他控制器

#import <UIKit/UIKit.h>

@classBlueViewController;

@classYellowViewController;

 

@interfaceSwitchViewController :UIViewController

@property (strong,nonatomic)BlueViewController*blueViewController;

@property (strong,nonatomic)YellowViewController *yellowViewController;

@end

 

生成- (IBAction)switchView:(UIBarButtonItem *)sender{}方法；

 

10、              根视图加载时插入蓝色视图

 

- (void)viewDidLoad {

    [superviewDidLoad];

    self.blueViewController = [[BlueViewControlleralloc]initWithNibName:@"BlueView"bundle:nil];

    [self.viewinsertSubview:self.blueViewController.viewatIndex:0];

}

 

11、              响应按钮事件，实现切换

 

- (void)didReceiveMemoryWarning {

    [superdidReceiveMemoryWarning];

    if (self.blueViewController.view.superview == nil) {

        self.blueViewController =nil;

    }else{

        self.yellowViewController =nil;

    }

}

 

- (IBAction)switchView:(UIBarButtonItem *)sender{

    if (self.yellowViewController.view.superview == nil) {

        if (self.yellowViewController.view == nil) {

            self.yellowViewController = [[YellowViewControlleralloc]initWithNibName:@"YellowView"bundle:nil];

        }

        [self.blueViewController.viewremoveFromSuperview];

        [self.viewinsertSubview:self.yellowViewController.viewatIndex:0];

    }else{

        if (self.blueViewController.view == nil) {

            self.blueViewController = [[BlueViewControlleralloc]initWithNibName:@"BlueView"bundle:nil];

        }

        [self.yellowViewController.viewremoveFromSuperview];

        [self.viewinsertSubview:self.blueViewController.viewatIndex:0];

    }

   

}

 

12、              实现动画切换

 

- (IBAction)switchView:(UIBarButtonItem *)sender{

    [UIViewbeginAnimations:@"View Flip"context:nil];

    [UIViewsetAnimationDuration:1.25];

    [UIViewsetAnimationCurve:UIViewAnimationCurveEaseInOut];

   

    if (self.yellowViewController.view.superview == nil) {

        if (self.yellowViewController.view == nil) {

            self.yellowViewController = [[YellowViewControlleralloc]initWithNibName:@"YellowView"bundle:nil];

        }

       

        [UIViewsetAnimationTransition:UIViewAnimationTransitionFlipFromRightforView:self.viewcache:YES];

       

        [self.blueViewController.viewremoveFromSuperview];

        [self.viewinsertSubview:self.yellowViewController.viewatIndex:0];

    }else{

        if (self.blueViewController.view == nil) {

            self.blueViewController = [[BlueViewControlleralloc]initWithNibName:@"BlueView"bundle:nil];

        }

       

        [UIViewsetAnimationTransition:UIViewAnimationTransitionFlipFromRightforView:self.viewcache:YES];

       

        [self.yellowViewController.viewremoveFromSuperview];

        [self.viewinsertSubview:self.blueViewController.viewatIndex:0];

    }

   

    [UIViewcommitAnimations];

}

 

13、              常见问题

问题1：

The file “Info.plist” couldn’t be openedbecause there is no such file

删除test文件没有删除干净；通过工程配置界面可以看到并删除。

 

问题2：

'Could not load NIB in bundle:'NSBundle </Users/c/Library/Developer/CoreSimulator/Devices/C817BF05-3462-41CB-9D9D-61CB794C78D4/data/Containers/Bundle/Application/F9EC13C2-7589-41CF-A010-48958E902262/Switch.app>(loaded)' with name 'SwitchViews''

self.switchViewController = [[SwitchViewControlleralloc]initWithNibName:@"SwitchView"bundle:nil];

初始化视图控制器是名称没有指定明确，区别大小写；
