我正在做一些自定義動畫以在單一方法中更改視圖。我已經使用[UIView setAnimationDidStopSelector:@selector(removeFromSuperview)]從superView中刪除了「fromView」，但我也希望在動畫結束後啓用用戶交互。從超級視圖中移除並啓用用戶交互

這裏是我的代碼：

-(void) switchFrom:(UIViewController*) fromViewController To:(UIViewController*) toViewController usingAnimation:(int) animation{ 
    UIView *fromView = fromViewController.view; 
    UIView *toView = toViewController.view; 
    /*************** SET ALL DEFAULT TRANSITION SETTINGS ***************/ 
    // Get the current view frame, width and height 
    CGRect pageFrame = fromView.frame; 
    CGFloat pageWidth = pageFrame.size.width; 

    // Create the animation 
    [UIView beginAnimations:nil context:nil]; 

    // Create the delegate, so the "fromView" is removed after the transition 
    [UIView setAnimationDelegate: fromView]; 
    [UIView setAnimationDidStopSelector:@selector(removeFromSuperview)]; 

    // Set the transition duration 
    [UIView setAnimationDuration: 0.4]; 

    /*************** IT DOESN'T WORK AT ALL ***************/ 
    [toView setUserInteractionEnabled:NO]; 
    [UIView setAnimationDelegate: toView]; 
    [UIView setAnimationDidStopSelector:@selector(setUserInteractionEnabled:)]; 
    [toView setUserInteractionEnabled:YES]; 

    // Add the "toView" as subview of "fromView" superview 
    [fromView.superview addSubview:toView]; 
    switch (animation) { 
     case AnimationPushFromRigh:{ 
      // Position the "toView" to the right corner of the page    
      toView.frame = CGRectOffset(pageFrame, pageWidth,0); 

      // Animate the "fromView" to the left corner of the page 
      fromView.frame = CGRectOffset(pageFrame, -pageWidth,0); 

      // Animate the "toView" to the center of the page 
      toView.frame = pageFrame; 

      // Animate the "fromView" alpha 
      fromView.alpha = 0; 

      // Set and animate the "toView" alpha 
      toView.alpha = 0; 
      toView.alpha = 1; 

      // Commit the animation 
      [UIView commitAnimations]; 
     } 
     . 
     . 
     .

任何想法，我怎麼能叫在setAnimationDidStopSelector這兩種方法，實際上使他們一起工作？

試過@safecase這樣的代碼，替換此評論塊：

/*************** IT DOESN'T WORK AT ALL *************** 
[toView setUserInteractionEnabled:NO]; 
[UIView setAnimationDelegate: toView]; 
[UIView setAnimationDidStopSelector:@selector(setUserInteractionEnabled:)]; 
[toView setUserInteractionEnabled:YES]; 
*************** IT DOESN'T WORK AT ALL ***************/ 
// Remove the interaction 
[toView setUserInteractionEnabled:NO]; 
[fromView setUserInteractionEnabled:NO]; 
// Create the animation 
[UIView animateWithDuration:0.4 animations:^{ 
    [fromView performSelector:@selector(removeFromSuperview)]; 
    } 
    completion:^(BOOL finished){ 
     [UIView animateWithDuration:0.4 
     animations:^{ 
      C6Log(@"finished"); 
      [toView performSelector: @selector(setUserInteractionEnabled:)]; 
     }]; 
    }];

的「toView」被刪除，而不是「fromView」除去:( 按鈕繼續在動畫過程中需要互動

我最終創建了UIView的類別擴展......並且它終於起作用了！

的UIView + Animated.h代碼

#import <UIKit/UIKit.h> 

@interface UIView (Animated) 

- (void) finishedAnimation; 

@end

的UIView + Animated.m代碼

#import "UIView+Animated.h" 

@implementation UIView (Animated) 

- (void) finishedAnimation{ 
    C6Log(@"FinishedAnimation!"); 
    [self removeFromSuperview]; 
    [[UIApplication sharedApplication] endIgnoringInteractionEvents]; 
} 

@end

然後，我#imported這個擴展在我的協調控制：

C6CoordinatingController.h部分代碼

#import "UIView+Animated.h"

之稱的setAnimationDidStopSelector選擇：

C6CoordinatingController.m部分代碼

// Create the delegate, so the "fromView" is removed after the transition 
[UIView setAnimationDelegate: fromView]; 

// Ignore interaction events during the animation 
[[UIApplication sharedApplication] beginIgnoringInteractionEvents]; 

// Set the transition duration 
[UIView setAnimationDuration: 0.4]; 

// Call UIView+Animated "finishedAnimation" method when animation stops 
[UIView setAnimationDidStopSelector:@selector(finishedAnimation)];

所以，我最終使用@ jaydee3和@Mundi概念和它的工作原理就像一個魅力！

謝謝你們！

您需要定義自己的方法，例如remove:並將其作爲選擇器傳遞，在該方法中，只需使用傳入的UIView即可將其刪除。

-(void)remove:(id)sender { 
    UIView *v = (UIView*)sender; 
    [v removeFromSuperview]; 
}

但我需要兩個「發件人」... toView（從superView中刪除）和fromView（以啓用交互）。我可以設置兩個不同的「setAnimationDidStopSelector」嗎？它會起作用嗎？ –

是不是「從視圖」原來的超視圖？如果是這樣，爲什麼不在上述方法中使用這種關係？ – Till

@Till，實際上，有一個「mainView」superview ...我可以嘗試這樣的... –

您可以使用此：

[UIView animateWithDuration:0.4 

animations:^{ [self performSelector:@selector(removeFromSuperview)]; // other code here} 

completion:^(BOOL finished){ [UIView animateWithDuration:0.4 

animations:^{ [self performSelector:@selector(setUserInteractionEnabled:)]; //other code here}]; }];

希望有幫助。

沒有...沒有工作... 代碼 –

不知何故，這段代碼不起作用......但它似乎真的在正確的道路......我會用它做一些測試，謝謝！ –

我想你可以用來啓用用戶交互
self.view.userInteractionEnabled = NO;

我這樣做了...但我需要它在動畫後重新啓用。 –

你知道嗎beginIgnoringInteractionEvents和endIgnoringInteractionEvents？通常，如果您在動畫期間不需要任何userInteraction，則可以使用這些。

無論如何，你仍然需要正確的回調來觸發它們。

不...我會看看如何使用它來代替「makeInteractionEnabled」。 –

它也很好......但我仍然不能同時執行「從視圖中刪除」和「endIgnoringInteractionEvents」... 我會嘗試創建一個方法（如@Mundi建議）刪除「fromView」並調用「endIgnoringInteractionEvents」。 –

從超級視圖中移除並啓用用戶交互
