iphone - 电子邮件形式的可点击文本 + 自定义警报视图

Question

我希望在我的应用程序中，电子邮件 ID 以文本形式书写，但该文本应该是可点击的。单击该弹出窗口时，应该会出现两个字段和两个按钮。这两个字段应该是可编辑的，以便在其中键入“发件人”和“消息正文”。两个按钮是发送和取消。请帮忙。

只需使用您的电子邮件地址创建按钮并在其上设置选择器，如下所示...

UIButton *BtnEmail = [UIButton buttonWithType:UIButtonTypeCustom];
[BtnEmail setBackgroundColor:[UIColor clearColor]];
[BtnEmail setTitle:@"YourEmailId" forState:UIControlStateNormal];
BtnEmail.frame = CGRectMake(85, 100, 150, 39 );/// set your frame
[BtnEmail addTarget:self action:@selector(EmailButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:BtnEmail];

并在动作事件（方法）中编写此代码..并将这两个委托添加到.h文件中MFMessageComposeViewControllerDelegate，MFMailComposeViewControllerDelegate并且1个框架名称是 MessageUI.framework

-(IBAction)EmailButtonClicked:(id)sender{

        if ([MFMailComposeViewController canSendMail]) {
            appDelegate.imgCapture = [self captureView];
            [appDelegate.imgCapture retain];
            MFMailComposeViewController *mailComposeViewController = [[MFMailComposeViewController alloc] init];
            NSString *mailBody = @"Set Your Body Message";


            [mailComposeViewController setMessageBody:mailBody isHTML:NO];
            mailComposeViewController.mailComposeDelegate = self;
            [self presentViewController:mailComposeViewController animated:YES completion:nil];
        } else {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"e-Mail Sending Alert"
                                                            message:@"You can't send a mail"
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK" 
                                                  otherButtonTitles:nil];
            [alert show];
            [alert release];
        }
}

这些波纹管方法是委托方法..

#pragma mark - MFMessage Delegate

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

我希望这可以帮助你...
