iOS 常用小功能

• 打电话
  • [UIApplication sharedApplication] 的 openURL方法

  NSURL *url = [NSURL URLWithString:@"tel://10086"];
  if ([[UIApplication sharedApplication] respondsToSelector:@selector(openURL:options:completionHandler:)]) {
        [[UIApplication sharedApplication] openURL:url
                                           options:@{}
                                 completionHandler:nil];
   } else {
        [[UIApplication sharedApplication] openURL:url];
   }
  

  • 通过 webview 打开

    if (!_webview) {
        _webview = [[UIWebView alloc] initWithFrame:CGRectZero];
        [self.view addSubview:_webview];
    }
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"tel://10086"]];
    [_webview loadRequest:request];
  

• 发短信
  • 打开 message 应用发送

    // 打开 message 发送，不可指定内容
    NSURL *url = [NSURL URLWithString:@"sms://10086"];
    [self openUrl:url];
  

  • MessageUI 内部发送短信，可指定任意内容

    // MessageUI 内部发送短信
    MFMessageComposeViewController *composeVC = [[MFMessageComposeViewController alloc] init];
    composeVC.body = @"套餐";
    composeVC.recipients = @[@"10086"];
    composeVC.messageComposeDelegate = self;
    [self presentViewController:composeVC animated:YES completion:nil];
  

• 发邮件
  • 打开mail 应用发送

     // 打开自带的 mail 应用发送
    NSURL *url = [NSURL URLWithString:@"mailto://[email protected]"];
    [self openUrl:url];
  

  • MessageUI 应用内发送mail，若本机未登录绑定邮箱会奔溃！

    // MessageUI 内部发送mail
    MFMailComposeViewController *composeVC = [[MFMailComposeViewController alloc] init];
    if (composeVC == nil) {
        NSLog(@"尚未登录邮箱");
        return;
    }
    //composeVC.body = @"套餐";
    [composeVC setToRecipients:@[@"[email protected]"]];
    [composeVC setSubject:@"主题"];
    [composeVC setMessageBody:@"这是一封测试邮件" isHTML:NO];
    composeVC.mailComposeDelegate = self;
    
    UIImage *image = [UIImage imageNamed:@"0.jpg"];
    [composeVC addAttachmentData:UIImageJPEGRepresentation(image, 0.6) mimeType:@"" fileName:@"123.jpg"];
    
    [self presentViewController:composeVC animated:YES completion:nil];
  

• 打开其他应用，如何查找 url schemes：
  • 下载他人的应用 ipa
  • 修改后缀名为 zip
  • 解压，打开 payload 文件夹
  • 右键 payload 文件夹 下的文件，显示包内容
  • 打开 info.plist 文件
  • url types 的 item0 的 url schemes

    NSURL *url = [NSURL URLWithString:@"weixin://"];
    if ([[UIApplication sharedApplication] respondsToSelector:@selector(openURL:options:completionHandler:)]) {
        [[UIApplication sharedApplication] openURL:url
                                           options:@{}
                                 completionHandler:nil];
    } else {
        [[UIApplication sharedApplication] openURL:url];
    }

• App Store评分，上线时候每一个 app 会分配一个 appid

    NSString *appid = @"your appid";
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"itms-apps://itunes.apple.com/cn/app/id%@?mt=8", appid]];
    [self openUrl:url];

以上
