我希望此方法检查条件是否为真,然后设置特定按钮(按钮)以获得我指定的图像.这是代码.

-(void)canAfford:(float) f: (UIButton*)button {
    if([self playerHas:(f)] == YES) {
        [button setImage:[UIImage imageNamed:nil] forState:UIControlStateNormal];
        [button setImage:[UIImage imageNamed:@"ButtonBGclicked.png"] forState:UIControlStateHighlighted];
    } else {
        [button setImage:[UIImage imageNamed:@"ButtonBG.png"] forState:UIControlStateNormal];
        [button setImage:[UIImage imageNamed:nil] forState:UIControlStateHighlighted];
    }
}

这是我得到的错误.
