UIWebView委托方法不起作用 [英] UIWebView Delegate Methods not Working

问题描述

**当我使用 self.myWeview.delegate = self 时，
UIWebView 无法加载 URL in UIWebView ...
但如果我将其设置为 self。 myWeview.delegate = nil ，
然后方法（委托）无法加载，但 URL 加载
这是代码：---

**When I Use self.myWeview.delegate = self , UIWebView can not load URL in UIWebView... But If I set it to self.myWeview.delegate = nil, then methods(delegate) can't load but URL is load this is the code:---

{
   self.myWeview.delegate = nil;
   NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
   NSURLRequest *request = [NSURLRequest requestWithURL:url];
   [myWebView loadRequest:request];
}

这工作正常，但无法调用委托方法。

This is working fine but couldn't called delegate methods.

另一方面

{
   self.myWeview.delegate = self;
   NSURL *url = [NSURL URLWithString:@"http:http://www.google.com"];
   NSURLRequest *request = [NSURLRequest requestWithURL:url];
   [myWebView loadRequest:request];
}

无法加载网址但调用委托方法

It Couldn't load URL but calls the delegate methods

推荐答案

最后我通过大量实验得到了答案，如果我们不使用这种方法

Finally I got my answer by lot of experiment,if we not using this method

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

除了所有方法在UIwebViewDelegate中正常工作

except that all methods are working fine in UIwebViewDelegate

1. -(void)webViewDidFinishLoad:(UIWebView *)webView
2. -(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
3. -(void)webViewDidStartLoad:(UIWebView *)webView
