ios - 无法更改 UILabel.titleLabel.text

Question

我尝试设置 titleLabel.text 但它不会从默认标题文本更改的奇怪问题。我已经在调试器中逐步检查它并检查了 taskTitle 值，它是正确的新值，但 titleButton.titleLabel.text 属性似乎没有接受值分配。

- (void)setChallengeTitle:(NSString *)taskTitle
{
    titleButton.titleLabel.text = taskTitle;
    titleButton.titleLabel.font = [UIFont fontWithName:@"Gotham Bold" size:18];



    CGSize stringsize = [taskTitle sizeWithFont:[UIFont fontWithName:@"Gotham Bold" size:18]];
    //I have to add a little bit since it doesn't seem to calculate the size of gotham correctly
    int buttonWidth = stringsize.width + 20;
    if (buttonWidth > 320)
        buttonWidth = 320;

    [titleButton setFrame:CGRectMake( (320 - buttonWidth)/2 ,10, buttonWidth, 40)];
}

您是否尝试过通过方法设置 UIButton 的文本？

尝试:

[titleButton setTitle:taskTitle forState:UIControlStateNormal]

UIControlStateNormal 将为所有状态设置标题。
