iOS获取系统短信，发送指定短信内容

现在在开发中应该会经常遇到点击邀请 发送短信给指定人员

点击邀请 弹出短信界面 并发送指定内容，手动点击发送即可

如果只要打开短信界面，并显示号码很简单，一句代码

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@sms://13666666666]];

但要指定短信内容 需要如下方法
1.先引入头文件

#import <MessageUI/MFMessageComposeViewController.h>

2.设置代理

MFMessageComposeViewControllerDelegate

3.实现代理方法

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{[self.mobileContactsVC dismissViewControllerAnimated:YES completion:nil];if (result == MessageComposeResultCancelled){NSLog(@"Message cancelled");}else if (result == MessageComposeResultSent){NSLog(@"Message sent");}else{NSLog(@"Message failed");}
}

1. 调用方法

/***  指定内容 打开SMS**  @param bodyOfMessage 要发送的内容*  @param recipients    要发送的号码*/
- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];if([MFMessageComposeViewController canSendText]){controller.body = bodyOfMessage;controller.recipients = recipients;controller.messageComposeDelegate = self;[self.mobileContactsVC presentViewController:controller animated:YES completion:nil];}   }```只要在需要调用的地方 调用方法即可

[self sendSMS:@"加入工付宝 领取红包金额" recipientList:[NSArray arrayWithObjects:[NSString stringWithFormat:@"%@", self.mobileContactsModel.mobile], nil]];
