Question

我想知道如何通过电子邮件发送webview链接。然后，当收件人收到电子邮件时，他们可以在safari中打开链接。提前谢谢！

我把这个BOOL放在我的代表中

 - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if ([[[request URL] scheme] isEqual:@"mailto"]) { 
    [[UIApplication sharedApplication] openURL:[request URL]]; return NO; 
} 
return YES; 
}

MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init]; 
[composer setMailComposeDelegate:self]; 
if ([MFMailComposeViewController canSendMail]) { 
    [composer setToRecipients:[NSArray arrayWithObjects:@"", nil]];
    [composer setSubject:@""]; 
    [composer setMessageBody:webview isHTML:YES]; 
    [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; 
    [self presentModalViewController:composer animated:YES];
    [composer release];
}

Answer 1

您在商家信息中做了两件不同的事情：

如果您想在点击网络视图中的MFMailComposeViewController链接时显示mailto:，则代码的第一部分（shouldStartLoadWithRequest）应该有效，除非您愿意必须将isEqual更改为isEqualToString：

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
  if ([[[request URL] scheme] isEqualToString:@"mailto"]) {  //Change in this line
      [[UIApplication sharedApplication] openURL:[request URL]]; return NO; 
  } 
  return YES; 
}

（请注意，用户在使用时会离开您的应用）

如果您想发送用户点击给某人的链接，您可以使用类似

的内容

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

MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init]; 
[composer setMailComposeDelegate:self]; 
if ([MFMailComposeViewController canSendMail]) { 
    [composer setToRecipients:[NSArray arrayWithObjects:@"", nil]];
    [composer setSubject:@"Link"]; 
    [composer setMessageBody:request.URL isHTML:YES]; 
    [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; 
    [self presentModalViewController:composer animated:YES];
    [composer release];
}

return YES; 
}

 MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init];
        [composer setMailComposeDelegate:self];
        if ([MFMailComposeViewController canSendMail]) {
            [composer setToRecipients:[NSArray arrayWithObjects:@"", nil]];
            [composer setSubject:@""];
            [composer setMessageBody:webview.request.URL.absoluteString isHTML:YES];
            [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
            [self presentModalViewController:composer animated:YES];
            [composer release];
        }
        else
            [composer release];
    }
}
