UIWebView在iPhone上的手机链接检测 [英] UIWebView phone links detection on iphone

问题描述

在我的代码中有一些奇怪的东西。我肯定忘记了什么，但我不知道什么。我尝试在UIWebView中处理电话，短信mailto和http链接。

there is something strange in my code. I'm sure to forget something but i don't know what. I try to handle phone, sms mailto and http links in an UIWebView.

这是我如何尝试：

1 /实例化UIWebView：

1/ instantiate the UIWebView :

webview = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,320,460)]; 
webview.opaque = NO;
webview.backgroundColor = [UIColor clearColor];
webview.userInteractionEnabled = YES;
webview.dataDetectorTypes = UIDataDetectorTypeAll;

2 /设置适当的委托：

2/ set the appropriate delegate :

[webview setDelegate: self];

3 /实现委托方法（简化版本）：

3/ implement the delegate method (simplified version here) :

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

  NSURL *requestURL = [[ request URL] retain];
  NSLog(@">>> %@", [requestURL scheme]);
  [requestURL release];
  return YES;
}

使用我的调试设备，当我触摸http链接时，会打印NSLog。当我触摸一个电话链接，我有这样的确认消息：

With my debug device when i touch an http link, the NSLog is printed. When i touch a tel link i have this kind of confirmation message :

使用iPhone模拟器，NSLog可以正确打印tel和http链接。

With the iPhone Simulator, tel and http links are correctly printed by NSLog.

推荐答案

现在任何人都可以这样做：

For anyone looking at this now, this will do it:

self.webView.dataDetectorTypes = UIDataDetectorTypeNone;
