Ios UIButton自定义按钮在选择时不会更改字体颜色

我用这段代码创建了一个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];

将您想要的背景色置于forState:高亮显示下

按下它时，它不在

UIControlStateNormal

中，而是

UIControlStateHighlighted

甚至不编译。当然当它按下它的按钮时？！否，其控件状态在按下时高亮显示，未选中。你知道我的意思，如果突出显示，在下面添加代码，这将解决你的问题。也许我不清楚。我只想让它在按下时改变。背景改变了，但标题没有改变。然后你把它放在forState下：突出显示，突出显示是按下时的状态。
