iPhone - MessageUI - 找不到框架消息

Question

我希望能够在我的应用程序中使用iPhone Mail.app,这样我的用户就可以在不离开应用程序的情况下发送共享电子邮件.我知道3.0使这成为可能.

我通过ctrl单击我的框架文件夹 - >添加现有框架来正确添加框架.

将此添加到我希望Mail.app出现的viewcontroller的头文件中.

#import <MessageUI/MessageUI.h>

我弹出一个UIAlert,在关闭时我调用下面的函数,我的代码中没有出现错误.我是否必须在Interface Builder中做一些额外的事情？错误消息是在下面

-(void)showEmailModalView {

    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self; // <- very important step if you want feedbacks on what the user did with your email sheet
    NSString * emailSubject = [[NSString alloc] initWithFormat:@"iPhone Subject Test"];
    [picker setSubject:emailSubject];


    NSString * content = [[NSString alloc] initWithFormat:@"iPhone Email Content"];

    // Fill out the email body text
    NSString *pageLink = @"http://mugunthkumar.com/mygreatapp"; // replace it with yours
    NSString *iTunesLink = @"http://link-to-mygreatapp"; // replate it with yours
    NSString *emailBody =
    [NSString stringWithFormat:@"%@\n\n<h3>Sent from <a href = '%@'>MyGreatApp</a> on iPhone. <a href = '%@'>Download</a> yours from AppStore now!</h3>", content, pageLink, iTunesLink];

    [picker setMessageBody:emailBody isHTML:YES]; // depends. Mostly YES, unless you want to send it as plain text (boring)

    picker.navigationBar.barStyle = UIBarStyleBlack; // choose your style, unfortunately, Translucent colors behave quirky.

    [self presentModalViewController:picker animated:YES];
    [picker release];
    [content release];
    [emailSubject release];


}

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

我的错误信息:

 ld: framework not found Message
 collect2: ld returned 1 exit status

Answer 1

做了一些研究后我发现我使用的教程非常好!代码没有错误,我的问题是我将MessageUI Framework添加到我的项目中的方式.

错误道. 按住Ctrl键并单击frameworks文件夹,然后选择add - > existing frameworks ..

正确的方式. 在xcode屏幕左侧的文件面板中打开"目标",双击项目名称.将弹出一个新窗口,在新窗口的底部,您可以添加一个新的链接库,通过单击左下角的小加号添加一个.向下滚动到MessageUI并选择Add.

如果您已经以错误的方式添加了MessageUI Framework,只需删除它并继续正确的方式.如果仍然无效,请尝试关闭xcode,重新启动并重建应用程序.

经过几个小时的寻找答案,这对我有用.
