UIButton setTitle不會立即更改標題

Question

我在編寫和閱讀UIButton的標題時遇到了麻煩。

我的問題：

// 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]是否有可能被稱為異步方法？ 如果是，是否有可能使此呼叫同步？

Answer 1

您可能需要currentTitle而不是titleLabel.text 。 或titleForState:UIControlStateNormal 。
