嗨，我可以从图库中获取图像，但是不会显示到收藏夹视图中。我已经编写了这样的代码
- (void)viewDidLoad
{
picker=[[UIImagePickerController alloc]init];
self.collectionView.delegate = self;
self.collectionView.dataSource = self;
[self.collectionView registerNib:[UINib nibWithNibName:@"MyCell" bundle:nil] forCellWithReuseIdentifier:@"CELL"];
}
- (IBAction)galleryClicked:(id)sender
{
NSLog(@"GalleryClicked");
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self;
[picker setAllowsEditing:YES];
[self presentViewController:picker animated:YES completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
inputImage= info[UIImagePickerControllerEditedImage];
NSLog(@"inputImage is :%@",inputImage);
[picker dismissViewControllerAnimated:YES completion:nil];
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
return 100;
}
- (MyCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
MyCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"CELL" forIndexPath:indexPath];
UIImageView *recipeImageView = (UIImageView *)[cell viewWithTag:100];
UILabel *descLabel = (UILabel *)[cell viewWithTag:110];
self.recipeImageView.image = inputImage;
return cell;
}
请有人建议我该怎么做。非常感谢帮助。
最佳答案
您需要将self.recipeImageView.image = inputImage;更改为recipeImageView.image = inputImage;。
