iOS 从app跳转到Safari、从app打开电话呼叫

1.从app跳转到Safari

1 NSString* strIdentifier = @"http://www.ybyb.com";

2             BOOL isExsit = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strIdentifier]];

3             if(isExsit) {

4                 NSLog(@"App %@ installed", strIdentifier);

5                 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strIdentifier]];

6             }

 

2.从app打开电话呼叫

 1  NSString *phoneNum = @"10086";// 电话号码

 2         

 3         UIWebView *phoneCallWebView;

 4         NSURL *phoneURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@",phoneNum]];

 5          if ( !phoneCallWebView ) {

 6         phoneCallWebView = [[UIWebView alloc] initWithFrame:CGRectZero];// 这个webView只是一个后台的View 不需要add到页面上来

 7             

 8              }

 9         [phoneCallWebView loadRequest:[NSURLRequest requestWithURL:phoneURL]];
