ios - 如何解决 NSRangeException

Question

你好我是 iPhone 编程的新手，我正在使用 EGOPhotViewer 并想通过使用此代码显示图像，

for ( recipeImages in recipeImages.imgArray) {

     photo = [[MyPhoto alloc] initWithImageURL:[NSURL URLWithString:recipeImages.recipie_img_url]name:recipeImages.recipe_name];
     NSLog(@"%@",recipeImages.recipie_img_url);

     MyPhotoSource *source = [[MyPhotoSource alloc] initWithPhotos:[NSArray arrayWithObjects:photo ,nil]];
       photoController = [[EGOPhotoViewController alloc] initWithPhotoSource:source];


}


        [APPDELEGATE.navigationController pushViewController:photoController animated:YES];

我得到了这个错误

我通过编写这段代码解决了这个问题

 NSMutableArray *localImagesArray = [[NSMutableArray alloc] init];

for ( recipeImages in recipeImages.imgArray) {
        photo = [[MyPhoto alloc] initWithImageURL:[NSURL URLWithString:recipeImages.recipie_img_url]name:recipeImages.recipe_name];
     NSLog(@"%@",recipeImages.recipie_img_url);
    NSLog(@"%@", [photo debugDescription]);
    [localImagesArray addObject:photo];
}


     MyPhotoSource *source = [[MyPhotoSource alloc] initWithPhotos:localImagesArray];
       photoController = [[EGOPhotoViewController alloc] initWithPhotoSource:source];



       [APPDELEGATE.navigationController pushViewController:photoController animated:YES];
