UIview動畫覆蓋一個視圖到另一個視圖

Question

我是新的iphone開發者我有問題uiview動畫ipad風景模式。我有兩個視圖view1（如分割視圖）和view2（覆蓋剩餘的窗口）。當我觸摸移動從右到左view2它將覆蓋視圖1與移動animation.at同時，當我觸摸移動從左到右view2來適合舊的position.please分享您的想法

隨着問候， Rajesh。

Answer 1

如果我理解正確，您需要2個視圖之間的滑動動畫。如果是這樣的話： 製作一個ViewController來保存這兩個視圖。這個視圖控制器的.m文件中定義包含以下並且得到由你的按鈕被稱爲過渡方法/其他動作觸發：

CGFloat windowWidth = self.mainView.frame.size.width; 
CGFloat windowHeight = self.mainView.frame.size.height; 
CGRect offScreenLeft = CGRectMake(-1*windowWidth, 0.0, windowWidth, windowHeight); 
CGRect onScreen = self.mainView.frame; 
CGRect offScreenRight = CGRectMake(windowWidth, 0.0, windowWidth, windowHeight); 

if (direction == rightToLeft) 
{ 
    rightView.frame = offScreenRight; 
    [self.view addSubview:rightView]; 
    [UIView animateWithDuration:0.65 
        animations:^{ 
         leftView.frame = offScreenLeft;  
         rightView.frame = onScreen; 
        } 
        completion:^(BOOL finished){ 
         [leftView removeFromSuperview]; 
        }]; 


}else if (direction == leftToRight){ 
    self.leftViewController.view.frame = offScreenLeft; 
    [UIView animateWithDuration:0.65 
        animations:^{ 
         rightView.frame = offScreenRight; 
         leftView.frame = onScreen; 
        } 
        completion:^(BOOL finished){ 
         [rightView removeFromSuperview]; 
        }]; 
    } 
} 

在一般情況下，要確保你所添加的子視圖的觀點目前在屏幕上，並確保你設置了合適的邊界。檢查你的觀點是不爲零：

if(myView){ 
    // not nil. thats good 
}else { 
    // nil. this is bad. make sure myView is being initialized properly (if at all) 
} 

最後，確保無論是不透明，也不在你的子視圖的alpha屬性設置爲0（你會在1，如果你想讓它完全顯示出來想這些和對於透明效果，在0和1之間）。

大家好我終於找到了答案，

- (void)viewDidLoad 
{ 

    UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipeHandle:)]; 
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)]; 
    [recognizer setNumberOfTouchesRequired:1]; 
    [secondView addGestureRecognizer:recognizer]; 
    [recognizer release]; 


    UISwipeGestureRecognizer *recognizerleft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipeHandle:)]; 
    [recognizerleft setDirection:(UISwipeGestureRecognizerDirectionLeft)]; 
    [recognizerleft setNumberOfTouchesRequired:1]; 
    [secondView addGestureRecognizer:recognizerleft]; 
    [recognizerleft release]; 
    [self.view addSubview:secondView]; 
    [super viewDidLoad]; 


} 
//To set the frame position of the view 

- (void)rightSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer 
{ 
    NSLog(@"rightSwipeHandle"); 


    [UIView beginAnimations:@"viewanimations" context:nil]; 
    [UIView setAnimationDuration:0.8]; 
    [UIView setAnimationDelegate:self]; 

    secondView.frame=CGRectMake(360, 0, 660, 768); 
    [UIView commitAnimations]; 
} 

//To set the frame position of the view 
- (void)leftSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer 
{ 
    NSLog(@"leftSwipeHandle"); 

    [UIView beginAnimations:@"viewanimations" context:nil]; 
    [UIView setAnimationDuration:0.8]; 
    [UIView setAnimationDelegate:self]; 

    secondView.frame=CGRectMake(200, 0, 858, 768); 
    [UIView commitAnimations]; 

}
