Question

我完全不知所措。我试图让用户通过MFMailComposeViewController发送电子邮件。但是，当我使用HTML正文设置MFMailComposeViewController时，MFMailComposeViewController会正确显示电子邮件，但在发送邮件时，我的应用程序会崩溃，并显示如下日志：

我非常有信心MFMailComposeViewController正确连接，因为当我将主体设置为纯文本时，一切都很好。此外，我的代码在iOS 4.3上使用HTML和纯文本工作正常。

这是相关代码：

@interface MailComposeDelegate: NSObject<MFMailComposeViewControllerDelegate>
@end

@implementation MailComposeDelegate

+(MailComposeDelegate*) sharedMailComposeDelegate
{
  static MailComposeDelegate* mcd = nil;
  if(!mcd) {
    mcd = [[MailComposeDelegate alloc]init];
  }

  return mcd;
}

-(void)mailComposeController:(MFMailComposeViewController*)controller 
          didFinishWithResult:(MFMailComposeResult)result 
                        error:(NSError*)error
{
  [app.window.rootViewController dismissModalViewControllerAnimated:NO];
}

...

@implementation M3AppDelegate(Email)

-(void)composeEmailWithSubject: (NSString*)subject
                       andBody: (NSString*)body
{
  // -- compose HTML message.

  MFMailComposeViewController* mc;
  if([MFMailComposeViewController canSendMail])
    mc = [[MFMailComposeViewController alloc] init];

  if(!mc) return;  

  mc.mailComposeDelegate = [MailComposeDelegate sharedMailComposeDelegate];

  [mc setSubject: subject];
  [mc setMessageBody: body isHTML: YES];

  // -- show message composer.

  [app.window.rootViewController presentModalViewController:mc animated:YES];
}

@end

哈，在这里回答我自己的问题：一些iOS5组件不会处理我的一些标记，即

<div style='font-size: 85%'>

DIV。但是，将相对大小更改为绝对像素高度的工作正常。

设置HTML正文时，MFMailComposeViewController在iOS5上崩溃
