動畫塊互相干擾

Question

我基本上一個接一個地運行兩個動畫，並且它似乎以某種方式干擾了彼此或UIView。我的代碼在5.0模擬器上工作得很好，但在4.3模擬器中遇到問題。

基本上我在屏幕上有一堆圖像。

[UIView animateWithDuration:0.1f 
          delay:0.0f 
         options:UIViewAnimationOptionCurveEaseIn 
        animations:^(void) { 
         //resizing the frame to make it bigger (original size is the new bigger size) 
         self.frame = CGRectMake(point.x - originalSize.width/2, point.y - originalSize.height/2 , originalSize.width, originalSize.height); 

        } 
        completion:^(BOOL complete){ 
         //I have a showArrow method that draws an arrow to the superview to show the user where to place their image 
         [self performSelector:@selector(showArrow) withObject:nil afterDelay:1]; 
        }]; 

一旦該塊完成，它運行showArrow，這只是顯示一個跳躍箭頭：

[UIView animateWithDuration:0.5f 
          delay:0.0f 
         options:UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat 
        animations:^(void) { 
         self.arrow.frame = CGRectMake(arrowOrigin.origin.x, arrowOrigin.origin.y - 200, arrow.frame.size.width, arrow.frame.size.height); 
         self.arrow.alpha = 0.5; 
        } 
        completion:NULL]; 

所以，正如我所說，這個作品當對象被觸動，它在尺寸可擴展至完美地在我的iPad和5.0模擬器上，但在4.3中，一旦第一個動畫運行，它似乎凍結了圖像的平移手勢或被觸摸的能力。任何想法，這與什麼呢？由於

嘗試添加UIViewAnimationOptionAllowUserInteraction面具的選項參數

[UIView animateWithDuration:0.1f 
         delay:0.0f 
        options:UIViewAnimationOptionCurveEaseIn | 
          UIViewAnimationOptionAllowUserInteraction 
       animations:^(void) { 
       // ... 

而且在showArrow：

[UIView animateWithDuration:0.5f 
         delay:0.0f 
        options:UIViewAnimationOptionAutoreverse | 
          UIViewAnimationOptionRepeat | 
          UIViewAnimationOptionAllowUserInteraction 
       animations:^(void) { 
       // ...
