1.發短信

頭文件

#import <MessageUI/MessageUI.h>

頭部代理

@interface ViewController ()<MFMessageComposeViewControllerDelegate>

發送信息

- (void)senderMessage{
    if([MFMessageComposeViewController canSendText]) {
        ///短信實例化
        MFMessageComposeViewController * messageVc = [[MFMessageComposeViewController alloc] init];
        
 
///目標號碼，可以多個
        messageVc.recipients = @[@"18888888888",@"15555555555"];
        messageVc.navigationBar.tintColor = [UIColor redColor];
        messageVc.body = @"發送的內容-發送的內容-發送的內容";
        messageVc.messageComposeDelegate = self;
        [self presentViewController:messageVc animated:YES completion:nil];
        [[[[messageVc viewControllers] lastObject] navigationItem] setTitle:
 
@"title"];
    }
    else {
        NSLog(@"當前設備不支持短信功能");
    }
    
}

代理方法實現

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
    ///dismiss MFMessageComposeViewController
    [controller dismissViewControllerAnimated:YES completion:nil];
    
 
if (result == MessageComposeResultSent) {
        NSLog(@"信息發送成功！");
    }
    else if (result == MessageComposeResultFailed){
        NSLog(@"信息發送失敗！");
    }
    else if (result == MessageComposeResultCancelled){
        NSLog(@"點擊了取消");
    }
    else{
        
    }
}

2.撥打電話

- (void)dialPhone{
    ///該方法直接撥打，不會彈出呼叫（取消）
    [[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"tel://18888888888"]];
    
    ///該方法會彈出是否取消呼叫
    UIWebView*callWebview =[[UIWebView alloc] init];
    NSURL *telURL =[NSURL URLWithString:@"tel:18888888888"];
    [callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];
    [self.view addSubview:callWebview];
}

3.發送郵件

- (void)senderEmail{
    NSString *urlStr =@"mailto:[email protected]?subject=郵件主題(此參數可不傳)&body=郵件內容(此參數可不傳)";
    NSURL *url = [NSURL URLWithString:urlStr] ;
    [[UIApplication sharedApplication] openURL:url];
}

4.發送QQ消息

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