如何在Objective C中拨打电话？

你可以发起一个电话

所以这可能会奏效

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:12125551212"]];

这是从我做的项目中剪切出来的:

NSString *phoneStr = [NSString stringWithFormat:@"tel:%@",phone_number];
NSURL *phoneURL = [NSURL URLWithString:phoneStr];
[[UIApplication sharedApplication] openURL:phoneURL];

了解如何提示用户拨打号码也可能有所帮助:

NSURL *phoneNumber = [NSURL URLWithString:@"telprompt://13232222222"];
[[UIApplication sharedApplication] openURL:phoneNumber];

NSURL *phoneNumber = [[NSURL alloc] initWithString: @"tel:867-5309"];
[[UIApplication sharedApplication] openURL: phoneNumber];
