实例方法presentModalViewController：未找到动画 [英] instance method presentModalViewController:animated not found
问题描述
我正在app delegate中实现电子邮件编辑器。
我不知道为什么，但我收到警告
I am implementing email composer in app delegate. I am not sure why , but i am getting an warning
实例方法presentModalViewController：动画未找到
"instance method presentModalViewController:animated not found"
仅在appdelegate，而我在其他viewcontroller中使用相同的方法，它可以顺利运行。
only at the appdelegate,whereas, i am using the the same method in my other viewcontroller, which works smoothly.
MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
mail.mailComposeDelegate = self;
if([MFMailComposeViewController canSendMail])
{
//Setting up the Subject, recipients, and message body.
[mail setToRecipients:[NSArray arrayWithObjects:@"abc@gmail.com",nil]];
UIImage *pic = [UIImage imageNamed:@"page0.png"];
NSData *exportData = UIImageJPEGRepresentation(pic ,1.0);
[mail addAttachmentData:exportData mimeType:@"image/jpeg" fileName:@"Picture.jpeg"];
[mail setSubject:@"dummy text"];
[mail setMessageBody:@"Please tell us what your concerns are and we will try to fix them" isHTML:NO];
//Present the mail view controller
[self presentModalViewController:mail animated:YES];
//release the mail [mail release];
}
[self presentModalViewController：mailer animated：YES]; 这是警告，应用程序在到达此处时会崩溃。
[self presentModalViewController:mailer animated:YES]; this is giving warning and app gets crashed,when reach here.
任何建议。
推荐答案
[self presentModalViewController:mail animated:YES];
是UIViewControllers方法。请检查您是否已从UIViewController扩展您的课程
is UIViewControllers Method . Please check whether you have extended your class from UIViewController
@interface abc : UIViewController
