我做了一个服装UIActivity课程。我喜欢在课堂上发送带附件的电子邮件,但我不能发送电子邮件,也不能在课堂上展示任何ViewControllers。我试图用这个来呈现Mail ViewController:
- (void)prepareWithActivityItems:(NSArray *)activityItems
{
NSString *subject = [NSString stringWithFormat:@"%@", [self.filePath lastPathComponent]];
NSString *messageBody = [NSString stringWithFormat:@"%@ was extracted with @FilyForiOS, visit", [self.filePath lastPathComponent]];
NSData *attachment = [NSData dataWithContentsOfFile:self.filePath];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:subject];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:nil];
[mc addAttachmentData:attachment mimeType:[[self.filePath lastPathComponent] pathExtension] fileName:[self.filePath lastPathComponent]];
[self presentViewController:mc animated:YES completion:nil]; // Here is the error: No visible @interface for 'MailTo' declares the selector 'presentViewController:animated:completion:'
}
有谁能告诉我如何从这个类中呈现一个ViewController?
答案 0 :(得分:1)
很抱歉我刚刚回答这个问题(我知道这是在不久前问的)但是这是我的回答:
#import <MessageUI/MessageUI.h>
@interface EmailActivity : UIActivity <MFMailComposeViewControllerDelegate>
@end
@implementation EmailActivity
- (NSString *)activityTitle
{
// Your title
return @"Email";
}
- (UIImage *)activityImage
{
// Your image
return [UIImage imageNamed:@"Email"];
}
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems
{
return YES;
}
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
[self activityDidFinish:YES];
}
- (UIViewController *)activityViewController
{
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc]init];
if ([MFMailComposeViewController canSendMail])
{
NSString *subject = [NSString stringWithFormat:@"%@", [self.filePath lastPathComponent]];
NSString *messageBody = [NSString stringWithFormat:@"%@ was extracted with @FilyForiOS, visit", [self.filePath lastPathComponent]];
NSData *attachment = [NSData dataWithContentsOfFile:self.filePath];
[mc setSubject:subject];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:nil];
[mc addAttachmentData:attachment mimeType:[[self.filePath lastPathComponent] pathExtension] fileName:[self.filePath lastPathComponent]];
mc.mailComposeDelegate = self;
return mc;
}
else
{
return nil;
}
}
@end
