在设置 TabBar 文字属性时,可能会遇到类似这样的警告:

button text attributes only respected for UIControlStateNormal, UIControlStateHighlighted and UIControlStateDisabled. state = 4 is interpreted as UIControlStateHighlighted.


UIBarButtonItem *item = [UIBarButtonItem appearance];
[item setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]} forState:UIControlStateSelected];

注意上述代码中使用了 UIControlStateSelected 这个状态,但警告中已经说明,在该情境中 按下状态 被认为是 UIControlStateHighlighted,因此我们只需要修改这个状态即可。
