【问题标题】:UIwebView load animation image not respond to UITapGestureRecognizerUIwebView 加载动画图像不响应 UITapGestureRecognizer
【发布时间】:2013-01-20 01:41:36
【问题描述】:
我使用UIWebView 作为UIView 的子视图从服务器加载动画图像(GIF)。
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:picLink]]];
我在UIView 中添加了点击手势,但 webView 禁用了这个手势(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!

【解决方案1】:
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");
}
