问题描述
在iOS 7中,我的UIButton游戏在错误的时间进行动画制作 - 迟到。这个问题在iOS 6上没有出现。我只是使用:
In iOS 7 my UIButton titles are animating in and out at the wrong time - late. This problem does not appear on iOS 6. I'm just using:
[self setTitle:text forState:UIControlStateNormal];
我希望这种情况立即发生,没有空白框架。这种眨眼特别令人分心,并引起人们对其他动画的注意。
I would prefer this happens instantly and without a blank frame. This blink is especially distracting and draws attention away from other animations.
推荐答案
这适用于自定义按钮:
[UIView setAnimationsEnabled:NO];
[_button setTitle:@"title" forState:UIControlStateNormal];
[UIView setAnimationsEnabled:YES];
对于系统按钮,你需要在重新启用动画之前添加它(谢谢@Klaas):
For system buttons you need to add this before re-enabling animations (thank you @Klaas):
[_button layoutIfNeeded];
