UIActionsheet button 颜色

用这种方式不好使，显示actionSheet.subviews 为空
for (id obj in actionSheet.subviews) {

    if ([obj isKindOfClass:[UIButton class]]) {

        UIButton *btn=(UIButton *)obj;

        [btn setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];

    }
}

- (void) changeTextColorForUIActionSheet:(UIActionSheet*)actionSheet {
    UIColor *tintColor = [UIColor redColor];

    NSArray *actionSheetButtons = actionSheet.subviews;
    for (int i = 0; [actionSheetButtons count] > i; i++) {
        UIView *view = (UIView*)[actionSheetButtons objectAtIndex:i];
        if([view isKindOfClass:[UIButton class]]){
            UIButton *btn = (UIButton*)view;
            [btn setTitleColor:tintColor forState:UIControlStateNormal];

        }
    }
}

确保这个方法是在 showInView 之后调用的，如果在 showInView 之前调用，除了 cancel button 之外的所有 button 都会被上色。
