iOS SDK:如何调用电子邮件应用程序？

Question

在我的iPad应用程序中,我想用自定义正文文本调用iPad的电子邮件应用程序.发件人和主题将为空,我想要设置的唯一参数是电子邮件的文本.我怎么能这样做？

谢谢!

Answer 1

为什么不在应用内打开电子邮件编辑器？

MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];

[mailController setSubject:@"my subject"];                  
[mailController setMessageBody:@"my message" isHTML:NO];

mailController.mailComposeDelegate = self;

UINavigationController *myNavController = [myViewController navigationController];

if ( mailController != nil ) {
    if ([MFMailComposeViewController canSendMail]){
        [myNavController presentModalViewController:mailController animated:YES];
    }
}

[mailController release];

Answer 2

请参阅MFMailComposeViewControllerApple的文档.你可以像这样使用它:

MFMailComposeViewController *controller=[[MFMailComposeViewController alloc]init];
controller.delegate = self;
[controller setMessageBody:<#yourBody#> isHTML:<#isHTML#>];
[self presentModalViewController:controller animated:YES];
[controller release];

不要忘记添加#import <MessageUI/MessageUI.h>您的.h文件.它将调用您委托中的方法,以便在取消或发送电子邮件(成功与否)时通知您.如果这对您有用,请告诉我.

Answer 3

NSString *body = @"Hello Mail";
NSString *mailtoURLString = [NSString stringWithFormat:@"mailto:?body=%@", [body stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailtoURLString]];

或者,正如Mihai建议的那样,看看MFMailComposeViewController哪个允许您在不离开应用程序的情况下发送邮件.
