在 iOS 4之后。苹果废弃了 webView.detectsPhoneNumbers = YES; 这个方法来检测电话 号码。现在任然可以继续使用，但是会出现警告。

更换为此方法：webView.dataDetectorTypes=UIDataDetectorTypePhoneNumber;

API文档上如此

typedefNS_OPTIONS(NSUInteger, UIDataDetectorTypes) {

UIDataDetectorTypePhoneNumber   =1<<0,// Phone number detection

UIDataDetectorTypeLink          =1<<1,// URL detection

#if __IPHONE_4_0 <= __IPHONE_OS_VERSION_MAX_ALLOWED

UIDataDetectorTypeAddress       =1<<2,// Street address detection

UIDataDetectorTypeCalendarEvent =1<<3,// Event detection

#endif

UIDataDetectorTypeNone          =0,// No detection at all

UIDataDetectorTypeAll           =NSUIntegerMax// All types

};
