我有一種方法來動畫和重置下面給出的視圖。UIView動畫在IOS 7中不能正常工作
-(void)animateToFocus:(BOOL)animate index:(NSInteger)index {
if (animate) {
[UIView beginAnimations:@"Scroll" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationsEnabled:YES];
self.view.frame = CGRectMake(0, -50*index, self.view.bounds.size.width, self.view.bounds.size.height);
[UIView commitAnimations];
} else {
[UIView beginAnimations:@"Scroll" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationsEnabled:YES];
self.view.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height);
[UIView commitAnimations];
}
}
當我在這個方法中傳遞YES和一個標記時,它會動畫到頂部,當我傳遞NO時,它將重置視圖。 它完美IOS6中。當我更新到IOS 7,重置完成爲:
它不會動畫completeley和黑色空間出現在底部。你能幫我解決這個問題嗎?
