自定义单元格不显示 PFImageView? [英] Custom cell not displaying PFImageView?

问题描述

我有一个使用 NIB 的自定义 PFTableViewCell.我所有的自定义标签都会显示，但我的 PFImageView 没有.我将所有内容更改为 UIImageView 只是为了确保我的 Parse 调用没有问题，但即使在我的资源中设置静态图像，我也无法让它工作.

I have a custom PFTableViewCell using a NIB. All of my custom labels display, but my PFImageView does not. I changed everything to a UIImageView just to make sure it wasn't something wrong with my Parse call, but I couldn't get it to work even with setting a static image in my resources.

我的单元格的类设置为 foodCell 并且 foodcell.h 设置为所有者.

My cell's class is set as foodCell and foodcell.h is set as the owner.

这是我的 NIB

这是我的 foodCell.h，用于显示 PFImageView 的出口:

Here is my foodCell.h to show the outlet of the PFImageView :

#import <Parse/Parse.h>

@interface foodCell : PFTableViewCell

@property (weak, nonatomic) IBOutlet NSObject *foodCell;

@property (weak, nonatomic) IBOutlet UILabel *priceLabel;

@property (weak, nonatomic) IBOutlet UILabel *foodDescription;

@property (weak, nonatomic) IBOutlet UILabel *foodTitle;

@property (strong, nonatomic) IBOutlet PFImageView *foodPic;

@end

现在我在这里配置我的单元.同样，除了 foodCell.foodPic.file :

Now here is where I configure my cell. Again, all of my other code here works, except the foodCell.foodPic.file :

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {

    static NSString *CellIdentifier = @"foodCell";
    foodCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    if (cell == nil) {
        cell = [[foodCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];

    }

    cell.foodPic.file = [object objectForKey:@"foodImage"];
    cell.foodTitle.text = [object objectForKey:@"foodName"];
    cell.foodDescription.text = [object objectForKey:@"foodDescription"];

    NSString *myString = [@"$" stringByAppendingString:[NSString stringWithFormat:@"%1@", [object objectForKey:@"foodPrice"]]];

    cell.priceLabel.text = myString;

    return cell;
}

推荐答案

根据 Parse 文档，你应该为那个 PFImageView

As per Parse documentation, you should call loadInBackground for that PFImageView

cell.foodPic.file = [object objectForKey:@"foodImage"];
[cell.foodPic loadInBackground];
