加載視圖控制器一個在另一個與延遲後在容器視圖

Question

載入多個視圖控制器一前一後與延遲這樣

-(void)playpauseAction:(id)sender { 
if([audioPlayer isPlaying]) 
{ 
[sender setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateSelected]; 
[audioPlayer pause]; 
[self pauseTimer]; 
[self pauseLayer:self.view.layer]; 
}else{ 
[sender setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateNormal]; 
[audioPlayer play]; 
[self resumeTimer]; 
[self resumeLayer:self.view.layer]; 
if(isFirstTime == YES) 
    { 
self.timer = [NSTimer scheduledTimerWithTimeInterval:11.0 
            target:self 
            selector:@selector(displayviewsAction:) 
            userInfo:nil 
            repeats:NO]; 
     isFirstTime = NO; 
    }}} 

- (void)displayviewsAction:(id)sender 
    { 
    First *firstController = [[First alloc] init]; 
    firstController.view.frame = CGRectMake(0, 0, 320, 480); 
    CATransition *transitionAnimation = [CATransition animation]; 
    [transitionAnimation setDuration:1]; 
    [transitionAnimation setType:kCATransitionFade];  
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]];  
    [self.view.layer addAnimation:transitionAnimation forKey:kCATransitionFade]; 
    [self.view addSubview:firstController.view]; 
    [self.view addSubview:toolbar]; 
    [firstController release]; 
    self.timer = [NSTimer scheduledTimerWithTimeInterval:23 target:self selector:@selector(Second) userInfo:nil repeats:NO];  
    } 

    -(void)Second 
    { 
Second *secondController = [[Second alloc] init]; 
secondController.view.frame = CGRectMake(0, 0, 320, 480); 
CATransition *transitionAnimation = [CATransition animation]; 
[transitionAnimation setDuration:1]; 
[transitionAnimation setType:kCATransitionReveal]; 
[transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; 
[self.view.layer addAnimation:transitionAnimation forKey:kCATransitionReveal]; 
[self.view addSubview:secondController.view]; 
[self.view addSubview:toolbar]; 
[secondController release]; 
self.timer = [NSTimer scheduledTimerWithTimeInterval:27 target:self selector:@selector(Third) userInfo:nil repeats:NO]; 
} 

要求是增加一個容器視圖和加載所有視圖控制器在containerview。

因此，加載視圖中可以創建的UIView和容器視圖這樣

- (void)loadView 
    { 
// set up the base view 
CGRect frame = [[UIScreen mainScreen] applicationFrame]; 
UIView *view = [[UIView alloc] initWithFrame:frame]; 
view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; 
view.backgroundColor = [UIColor blueColor]; 

// set up content view a bit inset 
frame = CGRectInset(view.bounds, 0, 100); 
_containerView = [[UIView alloc] initWithFrame:frame]; 
_containerView.backgroundColor = [UIColor redColor]; 
_containerView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; 
[view addSubview:_containerView];} 

在AppDelegate中能做到這樣

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
    { 
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 

ContainerViewController *container = [[ContainerViewController alloc] init];  
self.window.rootViewController = container; 


// make an array of 23 PageVCs 
NSMutableArray *controllers = [NSMutableArray array]; 
    [controllers addObject:firstcontroller]; 
    [controllers addObject:secondcontroller]; 
    [controllers addObject:.....]; 
    [controllers addObject:twentythreecontroller]; 

for (int i=0; i<23; i++) 
{ 
    First *firstController = [[First alloc] init]; 

[controllers addObject:firstcontroller, secondcontroller, .....,twentythreecontroller]; 
} 

// set these as sub VCs 
[container setSubViewControllers:controllers]; 

    [self.window makeKeyAndVisible]; 
    return YES;} 

加載所有viewcontrollers集裝箱鑑於這樣會好的或者在這裏做錯事。

感謝此幫助。

謝謝。

首先除去的NSTimer並使用performSelector：withObject：afterDelay：方法是這樣的：

// add delay and method according to your requirement 
[self performSelector:@selector(oneView) withObject:nil afterDelay:10]; 

-(void)oneView 
{ 
    //add firstView and perform second selector 
    [self performSelector:@selector(secondView) withObject:nil afterDelay:10]; 
} 

-(void)secondView 
{ 
    //add secondView and perform thirdselector 
    [self performSelector:@selector(thirdView) withObject:nil afterDelay:10]; 
} 

goes on .......................
