UIImage imageNamed returns nil 除了第一张图片

Question

我正在使用 [UIImage imageNamed:@"filename"] 方法从我的应用程序 image.xcassets 加载图像，只有第一张图像正确加载，然后是其余图像returns 零并使应用程序崩溃。下面是我的代码：

[self.imagePicker addImage:[UIImage imageNamed:@"image0-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image1-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image2-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image3-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image4-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image5-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image6-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image7-150x277"]];
[self.imagePicker addImage:[UIImage imageNamed:@"image8-150x277"]];

这是我的 addImage 方法：

- (void)addImage:(UIImage *)image 
{
    [_images addObject:image];
    [_thumbs addObject:image];
}

我已经检查了这个 question 并尝试了其中的所有内容，包括文件名检查并确保图像是 Retina 2x，但没有任何效果。关于可能出错的任何想法？

这是崩溃日志：

以及目标会员的屏幕截图：

Answer 1

屏幕截图中的图像名称似乎与您在代码中使用的名称不同！在代码中它最后有一个“277”，而在图像名称中它是一个“227”
