Question

MFMessageComposeViewController在ios8上没有显示发送按钮和消息正文，当点击收件人列表键盘出现并发送按钮时，消息体显示出来。以下是消息功能的代码：

MFMessageComposeViewController *msgController = [[MFMessageComposeViewController alloc] init] ;
if([MFMessageComposeViewController canSendText])
{
     if (msgController)
      {
           msgController = nil;
           msgController = [[MFMessageComposeViewController alloc] init] ;
      }
NSString *messageBody =@"helloWorld";
msgController.body = messageBody;
msgController.recipients = numberArray;
msgController.messageComposeDelegate = (id)self;
[self presentViewController:msgController animated:YES completion:^{}];

提前致谢。

Answer 1

首先将MessageUI框架添加到您的应用程序框架，然后

#import <MessageUI/MessageUI.h>
@interface class() 
<MFMailComposeViewControllerDelegate>
{
....
}
@end

然后在你的类实现中写

     if ([MFMailComposeViewController canSendMail])
     {
         MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
         [mail setMailComposeDelegate:self];
         [mail setSubject:@"Subject goes here..."];
         [mail setMessageBody:@"Message body goes here..." isHTML:NO];
         [self presentViewController:mail animated:YES completion:NULL];
     }

并实现MFMailcomposeViewController的委托，如

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

正文中应该有收件人和一些信息以启用＆＃34;发送＆＃34;按钮。

以下是供参考的链接：
