我很感謝有人能幫助我找到解決下一種情況的方案。動畫視圖的框架重定位與另一個視圖重疊
我想動畫的UIView到一個點到另一個（我能夠做到這一點，請檢查下面的代碼）的位置，但我有另一個UIView在中間..實際上這第二個視圖定位立即在我想要移動的視圖之後。我想要完成的基本上是避免在第二個視圖上看到動畫。
//second view placed at position x = 100, width = 20, height = 20
UIView *secondView = [[UIView alloc] initWithFrame:CGRectMake(100, 0, 20, 20)];
seconView.backgroundColor = [UIColor redColor];
[self.superview addSubview:secondView];
//from now on, this code occurs when tapping a button
//main view placed at position x = 0, width = 100, height = 20
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 20)];
view.backgroundColor = [UIColor yellowColor];
[self.superview addSubview:view];
[UIView beginAnimations:@"moveView" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
[UIView setAnimationDuration:0.7f];
//main view will be moved to position x = 120, meaning that it will go through the second view.
subView.frame = CGRectOffset(view.frame, view.frame.size.width + seconView.frame.size.width, 0);
[UIView commitAnimations];
我一直在玩z位置，不透明，不透明度，透明度和bringToFront性質沒有成功可言。
