如何將動畫GIF寫入iOS相機膠捲？

Question

你如何爲iOS相機膠捲寫入動畫GIF？據我所知，照片庫應用程序是無法播放的動畫，但例如發送電子郵件時，等

我已經試過我應該能夠將其導入：

UIImageWriteToSavedPhotosAlbum([UIImage imageWithData:self.imageData], nil, nil, nil); 

但這似乎將其轉換爲JPG格式。

創建一個ALAssetLibrary實例。使用此方法與您NSData：writeImageDataToSavedPhotosAlbum:metadata:completionBlock:

您可以在iOS的電子郵件附件這樣使用GIF。

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
picker.mailComposeDelegate = self; 

[picker setSubject:@""]; 

// Attach an image to the email 
NSString *path = [[NSBundle mainBundle] pathForResource:@"Your image name" ofType:@"gif"]; 
NSData *myData = [NSData dataWithContentsOfFile:path]; 
[picker addAttachmentData:myData mimeType:@"image/gif" fileName:@"photo name"]; 

NSString *emailBody = @""; 
[picker setMessageBody:emailBody isHTML:NO]; 

[self presentModalViewController:picker animated:YES]; 
[picker release];
