Xcode, iphone - Make image animation move in specific direction
提问by arvin Arabi
I'm creating an animated ball which should move across the screen. I want to make it move towards the center of the screen as if it is attracted by the center. How can I do this?
我正在创建一个应该在屏幕上移动的动画球。我想让它向屏幕中心移动，就好像它被中心吸引一样。我怎样才能做到这一点？

You can try this code
你可以试试这个代码
[UIView beginAnimations:nil context:NULL]; //starting Animation
[UIView setAnimationDuration:1.0];
[UIView setAnimationRepeatCount:10];
[UIView setAnimationRrepeatAutoreverses:YES];
CGPoint position = 200.0f;
position.y = 200.0f;
position.x = 150.0f;
img.center = position;
[UIView commitAnimations];
If it is cocos2d,You can use Move method,
如果是cocos2d，可以使用Move方法，
id move = [CCMoveTo actionWithDuration:3 position:ccp(160,240);
[sprite runAction:move];

image.center = CGPointMake(image.center.x + 10, image.center.y);
