Question

ios uiwebview捕获是不是点击的链接或者js操作

Answer 1

UIWebView的Delegate方法中有

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType;

其中navigationType可以判断出来该事件是UIWebView的loadRequest 还是touch URL连接

typedef enum {
UIWebViewNavigationTypeLinkClicked,
UIWebViewNavigationTypeFormSubmitted,
UIWebViewNavigationTypeBackForward,
UIWebViewNavigationTypeReload,
UIWebViewNavigationTypeFormResubmitted,
UIWebViewNavigationTypeOther
} UIWebViewNavigationType;

在UIWebView加载的时候navigationType == UIWebViewNavigationTypeOther
在UIWebView加载完成后，用户点击一个连接时navigationType == UIWebViewNavigationTypeLinkClicked。

这样就可以区分UIWebView是加载（在UIWebView中显示网页）还是连接（在Safari中显示网页）
