在延迟后触发方法而不滥用 [UIView animateWithDuration]?
我有一个 UIViewController 应该控制 2 个 UIImageView 淡入。
我设法使用 UIView animateWithDuration 方法为它们设置动画,如下所示:
[UIView animateWithDuration:1.5
animations:^{
[mFrontpageTitle setAlpha:0];
[mFrontpageTitle setAlpha:1];
}
completion:^(BOOL finished){
[self AnimatePause];
}];
并
-(void)AnimatePause {
[UIView animateWithDuration:5.0
animations:^{
[mFrontpageTitle setAlpha:0.99];
[mFrontpageTitle setAlpha:1];
}
completion:^(BOOL finished){
[self AnimateAuthor];
}];
触发下一个动画。现在,创建从 0.99 到 1.0 的过渡并不是很干净。
有没有更好的方法通过定义持续时间来触发块或发送消息?
谢谢祖帕
I have a UIViewController that should control 2 UIImageViews to fade in.
I managed to animate them using the UIView animateWithDuration method, like this:
[UIView animateWithDuration:1.5
animations:^{
[mFrontpageTitle setAlpha:0];
[mFrontpageTitle setAlpha:1];
}
completion:^(BOOL finished){
[self AnimatePause];
}];
and
-(void)AnimatePause {
[UIView animateWithDuration:5.0
animations:^{
[mFrontpageTitle setAlpha:0.99];
[mFrontpageTitle setAlpha:1];
}
completion:^(BOOL finished){
[self AnimateAuthor];
}];
which fires the next animation. Now, creating a transition from .99 to 1.0 is not very clean.
Is there a better way to trigger a block or sending a message by just defining a duration?
thanks
