UIButton setTitle 不会立即更改标题

Question

我在书写和阅读UIButton 的标题时遇到了麻烦。

我的问题：

// If I execute this line of code everything works fine, the title gets changed in the UI
[self.lastButtonPressed setTitle:stringDate forState:UIControlStateNormal];

// In the next line of code I want to read the title I've set before, but everything I get is the title of the UIButton before I changed the title.
NSString *myText = [self.lastButtonPressed.titleLabel.text];

[UIButton setTitle] 有可能被异步调用吗？如果是，是否有可能使此调用同步？

Answer 1

您可能想要currentTitle 而不是titleLabel.text。或者titleForState:UIControlStateNormal。
