Question

我使用UIWebView作为UIView的子视图来从服务器加载动画图像（GIF）。

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:picLink]]];

我将点按手势添加到UIView，但是webView会停用此手势（UIWebView frame = UIView Frame和[view sendSubViewToBack:webView]。

如何解决？是否有另一种显示GIF图像的方法。谢谢！

您可以将兄弟UIView置于UIWebView的顶部，并将轻敲手势识别器添加到该兄弟姐妹中。代码可能如下所示：

- (void)viewDidLoad {
    [super viewDidLoad];

    UIView *containerView = [[UIView alloc] initWithFrame:self.view.bounds];
    [self.view addSubview:containerView];

    UIWebView *webView = [[UIWebView alloc] initWithFrame:containerView.bounds];
    [containerView addSubview:webView];
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://i.imgur.com/eezCO.gif"]]];

    UIView *frontView = [[UIView alloc] initWithFrame:containerView.bounds];
    [containerView addSubview:frontView];
    UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)];
    [frontView addGestureRecognizer:tapRecognizer];
}

- (void)tapped:(UITapGestureRecognizer *)tapRecognizer {
    NSLog(@"tapped");
}

UIwebView加载动画图像不响应UITapGestureRecognizer
