这是我的动画视图的一个小片段:
动画来自时我遇到了问题?到S,反之亦然。我正在设置适当的帧以离开屏幕,然后从另一个大小重新开启。为什么黑色按钮的大小会随着每次移动而减小?
-(void)moveToRight
{
//just made this method up, but my actual code
//special case
if (currentDay == 7) {
//move off the screen to the right
CGRect offScreenRightFrame = CGRectMake(self.circle.frame.origin.x + 60, self.circle.frame.origin.y, self.circle.frame.size.width, self.circle.frame.size.height);
//move to the left of the screen so we can animate it in

答案 0 :(得分:0)
我只是把我的逻辑......老实说,我不读/看你的代码/逻辑,但可能是我的想法为你工作;) 所以,我认为..你应该在公共变量中添加圆的大小作为默认大小。每当你富裕时设置这个大小。
if (currentDay == 0 || currentDay == 8)
{
// Here you need to set your default size.
}
可能是我的逻辑工作,因为 1 到 7 天它的工作正常,但是当 currentDay 富有 0 或 8 天。
谢谢:)
