iOS 拨打电话

 

下面是拨打电话的代码,按钮的触发事件

@property (nonatomic ,strong) UIAlertView *alertView;

- (IBAction)CallphoneBtn:(id)sender {

//用户体验

    _alertView=[[UIAlertView alloc]initWithTitle:@"确定需要打电话?" message:nil delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];

    [_alertView show];

}

//alertView代理,别忘记遵守协议

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

    if(buttonIndex==0)

    {

         // [_alertView cancelButtonIndex];

    }

    else

    {

//这个是关键代码

        NSString *number=@"132xxxxxxxx";

        [[UIApplication sharedApplication]openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel://%@",number]]];

   }

}
