Question

我在自定义表格单元格中有一个图像视图，我需要从表格视图委托中为其分配一张图片

  cell.imageViewLeft = [[UIImageView alloc] initWithImage:[UIImage imageNamed:fxObject.thumbnailName]];
    NSLog(@"%@, %@", [UIImage imageNamed:fxObject.thumbnailName],  cell.imageViewLeft.image);

日志给了我：

<UIImage: 0xb485310>, (null)

Answer 1

确保您的IBOutlets连接正确。

此外，请确保@ synthesize imageViewLeft！

cell.imageViewLeft.image = [UIImage imageNamed:fxObject.thumbnailName];

Answer 2

我必须初始化属性。

- (UIImageView *)imageViewLeft {
if (!_imageViewLeft) {
    _imageViewLeft = [[UIImageView alloc] init];
    _imageViewLeft.contentMode = UIViewContentModeScaleAspectFill;
    _imageViewLeft.clipsToBounds = YES;
    [self.contentView addSubview:_imageViewLeft];
}
return _imageViewLeft;
}

- (UIImageView *)imageViewRight {
if (!_imageViewRight) {
    _imageViewRight = [[UIImageView alloc] init];
    _imageViewRight.contentMode = UIViewContentModeScaleAspectFill;
    _imageViewRight.clipsToBounds = YES;
    [self.contentView addSubview:_imageViewRight];
}
return _imageViewRight;
}

其他一切都保持不变。我相信如果我们在没有NIB文件的情况下工作并且我们没有制作IBOutlet属性，那么初始化视图的正确方法。

将图像分配给表格单元格中的uiimageview
