UICollectionView如何从Parse查询

Question

我有 UICollectionView，我需要将图像下载到 UIImage 单元格。我怎样才能用 Parse 做到这一点？事实是我需要 class 解析下载所有图像。

这是我的源代码示例：

- (void)runQuery {
PFQuery *query = [PFQuery queryWithClassName:@"SwapPost"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    // You obviously need better error handling in here...
    self.myImage = objects;
    [self.myCollectionView reloadData];
}
 ];

}

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    // This is an assumption
    return 1;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return self.myImage.count;
}

Answer 1

此代码修复的问题：

(NSInteger)numberOfSectionsInCollectionView:

(UICollectionView *)collectionView {
        // This is an assumption
        return [receivedObject count];
    }

(NSInteger)collectionView:

(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
        self.imageCell.image = [NSArrayName objectAtIndex:indexPath.row];
    }
