打电话,发短信,发邮件,app跳转

1.打电话

- (IBAction)callPhone1:(id)sender {
    NSURL *url = [NSURL URLWithString:@"tel://18500441739"];
    [[UIApplication sharedApplication] openURL:url];
}

- (IBAction)callPhone2:(id)sender {
    NSURL *url = [NSURL URLWithString:@"telprompt://18500441739"]; 
    [[UIApplication sharedApplication] openURL:url]; }

- (IBAction)callPhone3:(id)sender {
    if (_webView == nil) {
        _webView = [[UIWebView alloc] initWithFrame:CGRectZero];
    }
    [_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"tel://18500441739"]]];
}

推荐使用第三种,第一个为私有API,第二个无法回到原来app

2.发短信

- (IBAction)sendMsg:(id)sender {
    NSURL *url = [NSURL URLWithString:@"sms://18500441739"];
    [[UIApplication sharedApplication] openURL:url];
}

- (IBAction)sendWithMsg:(id)sender {
    /*  必须要导入<MessageUI/MessageUI.h> */
    MFMessageComposeViewController *vc = [[MFMessageComposeViewController alloc] init];
    /*  消息内容  */
    vc.body = @"吃饭了没？";
    /*  收到消息的人列表  */
    vc.recipients = @[@"",@""];
    /*  MFMessageComposeViewControllerDelegate  */
    vc.messageComposeDelegate = self;
    [self presentViewController:vc animated:YES completion:nil];
}

建议使用第二种,第二个可以预编辑文字和发送列表发送完了以后会有代理方法调用

#pragma mark - MFMessageComposeViewControllerDelegate
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{
    [controller dismissViewControllerAnimated:YES completion:nil];
    if (result == MessageComposeResultCancelled) {
        NSLog(@"取消发送");
    }else if (result == MessageComposeResultFailed){
        NSLog(@"发送失败");
    }else if(result == MessageComposeResultSent){
        NSLog(@"发送成功");
    }else{
        NSLog(@"未知情况");
    }
}

3.发送邮件

- (IBAction)sendEmail:(id)sender {
    NSURL *url = [NSURL URLWithString:@"mailto://[e-mail]"];
    [[UIApplication sharedApplication] openURL:url];
}

- (IBAction)sendEmailWithMsg:(id)sender {
    NSLog(@"%@",[self class]);

    if (![MFMailComposeViewController canSendMail]) {
        NSLog(@"yes");
        return;
    }
    MFMailComposeViewController *vc = [[MFMailComposeViewController alloc] init];
    /*  收件人列表  */
    [vc setToRecipients:@[@"[e-mail]",@""]];
    /*  抄送人列表  */
    [vc setCcRecipients:@[@"[e-mail]"]];
    /*  密送人列表  */
    [vc setBccRecipients:@[@"[e-mail]",@"[e-mail]"]];
    /*  设置代理   MFMailComposeViewControllerDelegate*/
    [vc setMailComposeDelegate:self];
    /*  发送主题  */
    [vc setSubject:@"会议"];
    /*  发送内容，是否为HTML文档  */
    [vc setMessageBody:@"测试发邮件功能" isHTML:NO];

    /*  添加附件  */
    UIImage *image = [UIImage imageNamed:@"IMG_0993"];
    NSData *data = UIImagePNGRepresentation(image);
    [vc addAttachmentData:data mimeType:@"image/png" fileName:@"首页.png"];

    /*  跳转页面  */
    [self presentViewController:vc animated:YES completion:nil];

}

推荐 第二种方法，第二种方法也有代理方法的调用

#pragma mark - MFMailComposeViewControllerDelegate
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
    [controller dismissViewControllerAnimated:YES completion:nil];
    if (result == MFMailComposeResultCancelled) {
        NSLog(@"取消发送");
    }else if (result == MFMailComposeResultSent){
        NSLog(@"发送成功");
    }else if (result == MFMailComposeResultSaved){
        NSLog(@"保存邮件");
    }else if (result == MFMailComposeResultFailed){
        NSLog(@"发送失败");
    }else{
        NSLog(@"发送异常");
    }
}

4.跳转其他app

a.跳转浏览器

/*  跳入浏览器  */
- (IBAction)intoBorwer:(UIButton *)sender {
    /*
     如果想打开一些常见文件，比如html、txt、PDF、PPT等，都可以使用UIWebView打开
     只需要告诉UIWebView文件的URL即可

     至于打开一个远程的共享资源，比如http协议的，也可以调用系统自带的Safari浏览器
     */
    NSLog(@"%@",sender.titleLabel.text);
    NSString *urlStr = [NSString stringWithFormat:@"http://%@",sender.titleLabel.text];
    NSURL *url = [NSURL URLWithString:urlStr];
    [[UIApplication sharedApplication] openURL:url];
}

b.跳转到其他app

/*  跳入到其他的程序  */
- (IBAction)intoOtherApp:(id)sender {
    /*  在要跳入的app中设置  URL Types
     1.打开原文件
     2.选择Info.Plist文件
     3.添加URL types
     4.点开URL types 将URL identifier的值设为 ios.defaults.com
     5.在URL types中添加URL Schemes，并将其值设为 who
     6.访问的url为 who://ios.defaults.com
     */
    NSURL *url = [NSURL URLWithString:@"yds://ios.hgl.org"];
    [[UIApplication sharedApplication] openURL:url];
}
