ios - UIwebView 加载动画图像不响应 UITapGestureRecognizer

Question

我使用 UIWebView 作为 UIView 的 subview 从服务器加载动画图像 (GIF)。

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

然后我将 Tap 手势添加到我的 UIView，但是 webView 禁用了这个手势(UIWebView frame = UIView Frame 和 [查看 sendSubViewToBack:webView]。

如何解决？是否有另一种方法来显示 GIF 图像。谢谢!

您可以将同级 UIView 放在 UIWebView 之上，并将点击手势识别器添加到该同级。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");
}
