创建图像后的动画问题

大家好，这里是我的代码：

-(void) onTimer {
UIImage * image = [UIImage imageNamed:@"abouffer_03.png"];
imageView = [[UIImageView alloc] initWithImage:image];
[imageView setCenter:[self randomPointSquare]];
[[self view] addSubview:imageView];

ix=imageView.center.x;
iy=imageView.center.y;

X=(240-ix)/230;
Y=(160-iy)/230;

}

-(void)onTimer2{
imageView.center = CGPointMake(imageView.center.x + X, imageView.center.y + Y);

}

“onTimer”每 4 秒调用一次，并且“onTimer2”上有一个 CADisplayLink (60fps)。

我的问题是每次调用“onTimer”时“imageView”的动画都会停止；创建一个新的“imageView”，然后 imageView 使用“onTimer2”方法移动，然后停止并创建另一个“imageView”...

我想要的是“imageView”的动画继续并同时创建新的“imageView” ，请问我该怎么做？抱歉我的英语我是法国人：/

Hi every one here is my code :

-(void) onTimer {
UIImage * image = [UIImage imageNamed:@"abouffer_03.png"];
imageView = [[UIImageView alloc] initWithImage:image];
[imageView setCenter:[self randomPointSquare]];
[[self view] addSubview:imageView];

ix=imageView.center.x;
iy=imageView.center.y;

X=(240-ix)/230;
Y=(160-iy)/230;

}

-(void)onTimer2{
imageView.center = CGPointMake(imageView.center.x + X, imageView.center.y + Y);

}

"onTimer" is called every 4 seconds and there is a CADisplayLink (60fps) on "onTimer2".

My problem is that "imageView"'s animation stops every time "onTimer" is called; a new "imageView" is created then imageView move with "onTimer2" method then it stops and another "imageView" is created ...

What I want is that "imageView"'s animation continues and in parallel new "imageView"s are created, how can I do this please ? sorry for my english I'm french :/

您每次都使用相同的 imageView 对象来分配和初始化。您需要使用不同的imageView，例如：

-(void) onTimer {
    UIImage * image = [UIImage imageNamed:@"abouffer_03.png"];
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:<specify desired frame>];
    imageView.image = image;
    [imageView setCenter:[self randomPointSquare]];
    [[self view] addSubview:imageView];

    ix=imageView.center.x;
    iy=imageView.center.y;

    X=(240-ix)/230;
    Y=(160-iy)/230;

}

You are using same imageView object to alloc and initialize every time. You need to use different imageView, like:

-(void) onTimer {
    UIImage * image = [UIImage imageNamed:@"abouffer_03.png"];
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:<specify desired frame>];
    imageView.image = image;
    [imageView setCenter:[self randomPointSquare]];
    [[self view] addSubview:imageView];

    ix=imageView.center.x;
    iy=imageView.center.y;

    X=(240-ix)/230;
    Y=(160-iy)/230;

}
