objective-c - [UICollectionViewCell imageView] : unrecognized selector sent to instance

Question

我正在尝试使用 Collection View 并在其中显示静态图像，但出现以下错误:

[UICollectionViewCell imageView]: unrecognized selector sent to instance.

我已经配置了单元 identifire = Cell。

这是我的代码:

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    SSCollectionViewCell *cell = (SSCollectionViewCell *)[collectionView  dequeueReusableCellWithReuseIdentifier:CellIdentifier forIndexPath:indexPath];

    int imageNumber = indexPath.row % 10;

    cell.imageView.image = [UIImage imageNamed:[NSString stringWithFormat:@"Image%d.jpg",imageNumber]];

    return cell;
}

这里是sscollectionViewCell.h代码

@interface SSCollectionViewCell : UICollectionViewCell

@property (weak) IBOutlet UIImageView *imageView;

@end

这里是SSColletionViewCell.m代码

#import "SSCollectionViewCell.h"
@interface SSCollectionViewCell ()

@end


@implementation SSCollectionViewCell
@synthesize imageView;

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
    }
    return self;
}
@end

谁能指出我哪里出错了？

Answer 1

改变

[self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:reuseIdentifier];

到

[self.collectionView registerClass:[SSCollectionViewCell class] forCellWithReuseIdentifier:reuseIdentifier];
