使用uiimagepicker控制器时出现上述错误。这是我的代码：
- (BOOL) startCameraControllerFromViewController:(UIViewController *)controller andisImageFromCamera:(BOOL)isCameraCapture {
if(self.picker == nil) {
/**< instansiate UIImagePickerController object */
self.picker = [[UIImagePickerController alloc] init];;
}
/**< Check isSourceTypeAvailable for possible sources (camera and photolibrary) */
if (([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera] == NO) || ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO))
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Oops!! This feature is not supported on your device" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alertView show];
return NO;
}
self.picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
self.picker.delegate = self;
self.picker.mediaTypes =[NSArray arrayWithObjects: (NSString *) kUTTypeMovie, (NSString *) kUTTypeImage, nil];
self.picker.videoMaximumDuration = MAX_VIDEO_DURATION;
self.picker.allowsEditing = YES;
self.picker.videoQuality = UIImagePickerControllerQualityTypeMedium;
/**< if editing is required*/
[self presentViewController:self.picker animated:YES completion:^{
}];
return YES;
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
NSURL *videoURL = [info valueForKey:UIImagePickerControllerMediaURL];
NSString *pathToVideo = [videoURL path];
if(![pathToVideo isEqualToString:@""] && pathToVideo != nil) {
BOOL okToSaveVideo = UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(pathToVideo);
if (okToSaveVideo) {
//UISaveVideoAtPathToSavedPhotosAlbum(pathToVideo, self, @selector(video:didFinishSavingWithError:contextInfo:), NULL);
}
}
if ([info[UIImagePickerControllerMediaType] isEqualToString:(NSString *)kUTTypeMovie]) {
// video
isVideoFromGallery = YES;
isMediaTypeVideo = YES;
[self videoCaptureSaveAction:videoURL andMediaInfo:info];
}
else{
isMediaTypeVideo = NO;
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.previewImage = chosenImage;
self.capturedImageData = UIImageJPEGRepresentation(chosenImage, 90);
[self performSegueWithIdentifier:@"previewCapture" sender:self];
}
}
挑选视频正在运行。但是当我选择图像时，我会得到错误：[Generic]创建一个未知类型的图像格式是一个错误。我已经阅读了有关此错误的其他帖子，更改了委托方法，但仍然无法正常工作。请帮忙。
