Iphone 自动播放youtube错误？

此代码不起作用，我在

UIButton*b=[self-findButtonInView:YouTubePlayer]行上收到2条警告警告是：

“youtubeplyer”的本地声明隐藏实例变量
“SecondViewController”可能不响应“-findButtonInView:”

您应该在findButtonInView方法中调用
[YouTubePlayer view]
在SecondViewController.h文件中，添加行
-（UIButton*）findButtonInView:（UIView*）视图

这是怎么回事：-（UIButton*）findButtonInView:（UIView*）视图{UIButton*按钮=nil；[YouTubePlayer视图]；if（[view isMemberOfClass:[UIButton class]]）{return（UIButton*）视图；}if（view.subviews&&[view.subviews count]>0）{for（UIView*视图中的子视图.子视图）{button=[self-findButtonInView:subview]；if（button）return button；}}}}return button；}哇。你能用它更新你的问题吗，这会让它更容易阅读。。
    - (void)webViewDidFinishLoad:(UIWebView *)YouTubePlayer {
    UIButton *b = [self findButtonInView:YouTubePlayer];
    [b sendActionsForControlEvents:UIControlEventTouchUpInside];
}

- (UIButton *)findButtonInView:(UIView *)view {
    UIButton *button = nil;

    if ([view isMemberOfClass:[UIButton class]]) {
        return (UIButton *)view;
    }

    if (view.subviews && [view.subviews count] > 0) {
        for (UIView *subview in view.subviews) {
            button = [self findButtonInView:subview];
            if (button) return button;
        }
    }

    return button;
}
