按下 btn1 后，我无法更改 UIButton btn2 的标题.当我使用 _definition settitle:@"Show Word" forState: UIControlStateNormal 时，它会更改原始 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.

这是供您查看的代码，

- (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

尝试以下方式:

[btn2 setTitle:@"Show Word"]
