ios程序内实现打电话

邮件
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://[email protected]"]];
电话
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8004664411"]];
sms
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://466453"]];
浏览器
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunesconnect.apple.com"]]; 

两种方法:

 //1、系统的打电话代码，不返回当前程序：

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://1008611"]];

 //2、用UIWebView来实现，打电话结束后会返回当前应用程序：

 UIWebView *callPhoneWebVw = [[UIWebView alloc] init];
 NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"tel://1008611"]];
 [callPhoneWebVw loadRequest:request];
