在表格视图中显示图像

Question

我没有显示任何图像，只显示文件名。

目前我使用这个代码：

NSString *filePath = [[self documentsPath] stringByAppendingPathComponent:@""];

NSFileManager *imagesFileManager = [NSFileManager defaultManager];


imagesArr = [[imagesFileManager contentsOfDirectoryAtPath:filePath error:nil]filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"self ENDSWITH '.jpg'"]];


arryList = [[NSMutableArray alloc] initWithArray:[imagesArr copy]];//display text
imagesList = [[NSMutableArray alloc]init];//display image

for (NSString *anImage in arryList) {
    anImage = [NSString stringWithFormat:@"Documents/%@",anImage];
    [imagesList addObject:anImage];

}

Answer 1

在 for 循环中，您只需将文件路径而不是 UIImage 添加到数组中。

更改 for 循环如下：

NSString *docPath = [self documentsPath];

for (NSString *anImagePath in arryList) {
    anImagePath = [NSString stringWithFormat:@"%@/%@",docPath,anImagePath];
    UIImage *image = [UIImage imageWithContentsOfFile:anImagePath];
    if ( image )
      [imagesList addObject:image];
}
