iOS 调用短信后能回到应用

一般情况下,我们可以这样调用短信功能这样写

NSString *usrString = [NSString stringWithFormat:@"sms://%@", @"132424123124"];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:usrString]];

但是这样写之后有个缺点就是调用短信后回不来了

于是乎就有了下面的写法:

-(void)showMessageViewController:(NSString*)phoneNumber

{

if( [MFMessageComposeViewController canSendText] )//判断是否能发短息

{

MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc]init];

controller.recipients = [NSArray arrayWithObject:phoneNumber];//接收人,可以有很多,放入数组

controller.body = @"ssssssss";//短信内容,自定义即可

controller.messageComposeDelegate = self;//注意不是delegate

[self presentViewController:controller animated:YES completion:nil];

[[[[controller viewControllers] lastObject] navigationItem] setTitle:@"发送短信"];//修改短信界面标题

}

else

{

NSLog(@"不能发送短信");

}

}

这种写法是比较好的一种.
