iOS打电话、发短信、发邮件实例代码

本文实例为大家分享了iOS打电话、发短信、发邮件，指定QQ用户发送QQ消息的具体代码，供大家参考，具体内容如下

1.发短信

头文件

#import <MessageUI/MessageUI.h>

头部代理

@interface ViewController ()<MFMessageComposeViewControllerDelegate>

发送信息

- (void)senderMessage{
  if([MFMessageComposeViewController canSendText]) {
    ///短信实例化
    MFMessageComposeViewController * messageVc = [[MFMessageComposeViewController alloc] init];
    ///目标号码，可以多个
    messageVc.recipients = @[@"18888888888",@"15555555555"];
    messageVc.navigationBar.tintColor = [UIColor redColor];
    messageVc.body = @"发送的内容-发送的内容-发送的内容";
    messageVc.messageComposeDelegate = self;
    [self presentViewController:messageVc animated:YES completion:nil];
    [[[[messageVc viewControllers] lastObject] navigationItem] setTitle:@"title"];
  }
  else {
    NSLog(@"当前设备不支持短信功能");
  }
  
}

代理方法实现

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
  ///dismiss MFMessageComposeViewController
  [controller dismissViewControllerAnimated:YES completion:nil];
  if (result == MessageComposeResultSent) {
    NSLog(@"信息发送成功！");
  }
  else if (result == MessageComposeResultFailed){
    NSLog(@"信息发送失败！");
  }
  else if (result == MessageComposeResultCancelled){
    NSLog(@"点击了取消");
  }
  else{
    
  }
}

2.拨打电话

- (void)dialPhone{
  ///该方法直接拨打，不会弹出呼叫（取消）
  [[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"tel://18888888888"]];
  
  ///该方法会弹出是否取消呼叫
  UIWebView*callWebview =[[UIWebView alloc] init];
  NSURL *telURL =[NSURL URLWithString:@"tel:18888888888"];
  [callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];
  [self.view addSubview:callWebview];
}

3.发送邮件

- (void)senderEmail{
  NSString *urlStr =@"mailto:xxxxxxxx@xxxx.com?subject=邮件主题(此参数可不传)&body=邮件内容(此参数可不传)";
  NSURL *url = [NSURL URLWithString:urlStr] ;
  [[UIApplication sharedApplication] openURL:url];
}

4.发送QQ消息

- (void)senderQQ{
  ///111111111111为QQ号码
  NSString *url = @"mqq://im/chat?chat_type=wpa&uin=111111111111&version=1&src_type=web";
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}
