毛刺在UIView的與kCATransitionMoveIn

Question

滑動時，我有一個UINavigationController其滑動的UIView在從屏幕的底部，當用戶按下按鈕。

緊接着我設置視圖的「隱藏」屬性爲NO，不過，的UINavigationController的觀點有時完全出現在地方一幀，彷彿動畫片結束了。

這是顯示/代碼隱藏視圖：添加層時

- (void)showGUI: (bool)show 
{ 
CATransition *transition = [CATransition animation]; 
transition.duration = 0.5; 
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; 

if (!show) 
{ 
    transition.type = kCATransitionReveal; 
    transition.subtype = kCATransitionFromBottom; 
} 
else 
{ 
    transition.type = kCATransitionMoveIn; 
    transition.subtype = kCATransitionFromTop; 
} 

[navController.view.superview.layer addAnimation:transition forKey:nil]; 

navController.view.hidden = !show; 
}

CATransition動畫被施加/從你動畫添加到層中除去。如果切換隱藏的屬性不起作用，請嘗試刪除視圖。
