使用UICollectionViewCell作爲按鈕

Question

如何設置UICollectionViewCell作爲按鈕使用，該功能完成後也會重複使用。 我想用單元格作爲按鈕來添加來自我的照片庫的圖像。 代碼提取是我用來添加圖像的barbutton項目的功能。

- (IBAction)buttonTapped:(id)sender { 
_picker = [[UIImagePickerController alloc] init]; 
_picker.delegate = self; 
_picker.allowsEditing = NO; 
_picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
[self presentViewController:_picker animated:YES completion:nil]; 
} 



- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { 
[_images addObject:image]; 
[self saveNewImageToDb:image]; 
[self dismissViewControllerAnimated:_picker completion:^{ 
    [_collectionView reloadData]; 
}]; 
} 




-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker { 
[self dismissViewControllerAnimated:_picker completion:nil]; 
} 

Answer 1

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath { 

    NSLog(@"Selected cell = %d",indexPath.item); 

    _picker = [[UIImagePickerController alloc] init]; 
    _picker.delegate = self; 
    _picker.allowsEditing = NO; 
    _picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    [self presentViewController:_picker animated:YES completion:nil]; 


} 

Answer 2

您可以實現此功能：

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 
// something you do as function "buttonTapped" 
}
