ios - UIButton 自定义按钮不会在选择时更改字体颜色

Question

我正在使用这段代码创建一个 UIButton，但是当按下按钮时字体不会改变颜色。

_gameSlider = [UIButton buttonWithType:UIButtonTypeCustom];
    [_gameSlider setBackgroundImage:[[UIImage imageNamed:@"sliderBackgroundSticker"] resizableImageWithCapInsets:UIEdgeInsetsMake(22, 16, 22, 16)] forState:UIControlStateNormal];
    _gameSlider.frame = CGRectMake(0, 0, self.view.frame.size.width - 20, 70);
    newCnt = self.view.center;
    newCnt.y = newCnt.y + 120;
    _gameSlider.center = newCnt;
    [_gameSlider setTitle:@"PLAY" forState:UIControlStateNormal];
    [_gameSlider.titleLabel setFont:[UIFont fontWithName:@"Chalkduster" size:22]];
    [_gameSlider setTitleColor:[UIColor lightGrayColor] forState:UIControlStateNormal];
    [_gameSlider setTitleColor:[UIColor yellowColor] forState:UIControlStateSelected | UIControlStateHighlighted];
    [_gameSlider addTarget:self action:@selector(playButtonPressed) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:_gameSlider];

Answer 1

将您想要的背景颜色放在 forState:Highlighted 下。

当它被按下时，它不在 UIControlState Normal 和 UIControlState Highlighted 中。
