完成截图并尝试通过电子邮件将截图发送到应用程序时出现问题。通常,在发送文本时它可以完美运行,但是一旦发送屏幕截图,无论取消还是发送电子邮件,屏幕都不会消失。我可以知道这是什么问题吗?
这是我的代码。非常感谢你。
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
UIGraphicsBeginImageContext(self.view.frame.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * image = UIGraphicsGetimageFromCurrentimageContext();
UIGraphicsEndImageContext();
NSData * imageData = UIImageJPEGRepresentation(image,1.0);
if ( [MFMailComposeViewController canSendMail] ) {
MFMailComposeViewController * mailComposer = [[[MFMailComposeViewController alloc] init] autorelease];
mailComposer.delegate = self;
[mailComposer addAttachmentData:imageData mimeType:@\"image/jpeg\" fileName:@\"attachment.jpg\"];
/* Configure other settings */
[self presentModalViewController:mailComposer animated:YES];
}
}
}
- (void)mailComposeController:(MFMailComposeViewController*)controller{
[self dismissModalViewControllerAnimated:YES];
}
解决方法
您需要实现的委托方法是
mailComposeController:didFinishWithResult:error:
,而不是mailComposeController:
。有关详细信息,请参见文档。
