iphone上的UIWebView电话链接检测

UIWebView phone links detection on iphone(iphone上的UIWebView电话链接检测)

问题描述

我的代码有些奇怪.我肯定会忘记一些东西，但我不知道是什么.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.

这就是我尝试的方式:

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:

[webview setDelegate: self];

3/实现委托方法(这里是简化版):

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;
}

当我触摸一个 http 链接时，我的调试设备会打印 NSLog.当我触摸电话链接时，我会收到这种确认消息:

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.

很奇怪，不是吗?

推荐答案

对于现在正在看这个的任何人，都可以这样做:

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

self.webView.dataDetectorTypes = UIDataDetectorTypeNone;
