UIWebView Delegate Methods not Working [closed]

问题

**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];
}

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

On the other hand

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

It Couldn't load URL but calls the delegate methods

回答1:

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

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

回答2:

remove that extra http

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

回答3:

You have made the mistake in calling the URL ...

Try this :

NSURL *url = [NSURL URLWithString:@"http://www.google.com"];

回答4:

Use this code in your viewcontroller.h file

@interface ViewController : UIViewController<UIWebViewDelegate>

回答5:

set delegate to self then you need to implement the delegate

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
   return YES;
}

and also don't forget to confirm the protocol in .h file like this

@interface YourViewController : UIViewController<UIWebViewDelegate>
