一旦按下UI按钮，如何更改UI按钮标题？ [英] How to change UIbutton title once a UIbutton is pressed?

问题描述

按下btn1后，我无法更改UIButton btn2的标题。当我使用 _definition settitle：@Show WordforState：UIControlStateNormal 它改变了原来的btn1。

I am having trouble changing the title of UIButton btn2 once btn1 is pressed. When I use _definition settitle:@"Show Word" forState: UIControlStateNormal it changes the original btn1.

以下是您的评论代码，

- (IBAction)mynextPressed:(UIButton *)sender {

    //Display the string in the label field

    [self.WordDisplay setText:vocabulary];

    //reset center button with "show word"
    [_definitionPressed setTitle:@"Show Word" forState:UIControlStateNormal];
    NSLog(@"displaying word: %@", _definitionPressed.titleLabel);

}

推荐答案

尝试一下以下行：

[btn2 setTitle:@"Show Word"]
