UIView的子视图的动画 [英] UIView Subview for Animation

问题描述

我的目标是我的动画UI，和我使用的UIView动画。问题是我需要一个以上的动画回事的时间，但显然我只能在同一时间执行一个UIView的动画。我也问过关于这个主题$ P $问题pviously（多的UIView动画），和所有的应答者说我必须设置一个委托到动画像的方法animationDidStop：performSelector：，但如果我能，而不是子视图添加到主视图和每个同时执行的动画我想知道子视图。另外，我无法进行背靠背的动画，我想也许我可以执行的厂景的动画，然后对视图2没有下放。

例如：

  //头
@属性（非原子，强）的UIView *厂景;
@属性（非原子，保留）的UIView *视图2;//实施
@synthesize厂景;
@synthesize视图2;// viewDidLoad中
厂景= [[UIView的页头] initWithFrame：方法CGRectMake（0,0,480,640）;
视图2 = [[UIView的页头] initWithFrame：方法CGRectMake（0,0,480,640）;view1.backgroundColor =的UIColor clearColor]
view2.backgroundColor =的UIColor clearColor][performAnimationsOn视图1]; //我不知道code我会把在这里，因为code
                             //我平时用的是[UIView的beginAnimation：@动画
                             //背景：无];但是这是一个类的方法，我不
                             //知道如何在一个特定的子视图执行的动画。
[performAnimationsOn视图2];
 

解决方案

我没有看到这里的问题，如果你需要的是动画2 diffent意见同时做到以下几点：

  //首先添加这些子视图
[self.view addSubview：视图1];
[self.view addSubview：视图2];
[UIView的beginAnimations：@动画1上下文：无];
[UIView的setAnimationDidStopSelector：@selector（animationDidStop：完成：上下文:)];
[UIView的setAnimationDelegate：个体经营];
[UIView的setAnimationDuration：1];
//使用视图1移动，改变α，变更改造等东西..
[UIView的commitAnimations];
 

另外添加的功能

   - （无效）animationDidStop：（* NSString的）animationID完成：（NSNumber的*）完成环境：（无效*）上下文
{
    如果（[animationID isEqualToString：@动画1]）{
        [UIView的beginAnimations：@Animation2背景：无];
        [UIView的setAnimationDidStopSelector：@selector（animationDidStop：完成：上下文:)];
        [UIView的setAnimationDelegate：个体经营];
        [UIView的setAnimationDuration：1];
        //使用视图2移动，改变α，变更改造等东西..
        [UIView的commitAnimations];
    }
    否则，如果（[animationID isEqualToString：@Animation2]）{
        [UIView的beginAnimations：@动画3背景：无];
        [UIView的setAnimationDidStopSelector：@selector（animationDidStop：完成：上下文:)];
        [UIView的setAnimationDelegate：个体经营];
        [UIView的setAnimationDuration：1];
        //使用视图3移动，改变α，变更改造等东西..
        [UIView的commitAnimations];
    }
    //等等.....
}
 

该动画应顺序发生

My goal is to animate my UI, and I am using UIView animations. The problem is I need more than one animation going on at a time, but apparently I can only perform one UIView animation at a time. I have asked questions on this topic previously (Multiple UIView Animations), and all the responders say I have to set a delegate to the animation with a method like animationDidStop:performSelector: but I was wondering if I could instead add subviews to the main view and perform animations simultaneously on each subview. Also, I am unable to perform back to back animations, and I was thinking maybe I could perform an animation on view1 and then on view2 without delegating.

For example:

//Header
@property (nonatomic, strong) UIView *view1;
@property (nonatomic, retain) UIView *view2;

//Implementation
@synthesize view1;
@synthesize view2;

//ViewDidLoad
view1 = [[UIView alloc]initWithFrame:CGRectMake(0,0,480,640)];
view2 = [[UIView alloc]initWithFrame:CGRectMake(0,0,480,640)];

view1.backgroundColor = [UIColor clearColor];
view2.backgroundColor = [UIColor clearColor];

[performAnimationsOn View1]; //I don't know the code I would put here because the code 
                             //I usually use is [UIView beginAnimation:@"animation"
                             //context:nil]; but that is a class method and I am not
                             //sure how to perform an animation on a specific subview.
[performAnimationsOn View2];

解决方案

I dont see the problem here, if what you need is to animate two diffent views at once do the following:

//First add these subviews
[self.view addSubview:view1];
[self.view addSubview:view2];


[UIView beginAnimations:@"Animation1" context:nil];
[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:1];
//Do something with view 1 move, change alpha, change transformation etc..    
[UIView commitAnimations];

Also add the following function

- (void) animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{
    if ([animationID isEqualToString:@"Animation1"]) {
        [UIView beginAnimations:@"Animation2" context:nil];
        [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDuration:1];
        //Do something with view 2 move, change alpha, change transformation etc..    
        [UIView commitAnimations];
    }
    else if ([animationID isEqualToString:@"Animation2"]) {
        [UIView beginAnimations:@"Animation3" context:nil];
        [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDuration:1];
        //Do something with view 3 move, change alpha, change transformation etc..    
        [UIView commitAnimations];
    }
    //And so on.....
}

The animations should occur sequentially
