本篇IOS应用教程将为大家讲解IOS编程的知识点，看完这篇文章会让你对IOS编程的知识点有更加清晰的理解和运用。

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]];

}
