ios - 从文档文件夹获取所有图像

我有一些来自文档文件夹的图像。

现在，我想从文档文件夹中获取所有图像以在UIImageView中设置，而UIImageView必须在tableViewCell中进行设置。

怎么做？

请帮我！

尝试这个..

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *myPath = [paths objectAtIndex:0];
// if you save fies in a folder
//myPath = [myPath stringByAppendingPathComponent:@"folder_name"];

NSFileManager *fileManager = [NSFileManager defaultManager];
// all files in the path
NSArray *directoryContents = [fileManager contentsOfDirectoryAtPath:myPath error:nil];

// filter image files
NSMutableArray *subpredicates = [NSMutableArray array];
[subpredicates addObject:[NSPredicate predicateWithFormat:@"SELF ENDSWITH '.png'"]];
[subpredicates addObject:[NSPredicate predicateWithFormat:@"SELF ENDSWITH '.jpg'"]];
NSPredicate *filter = [NSCompoundPredicate orPredicateWithSubpredicates:subpredicates];

NSArray *onlyImages = [directoryContents filteredArrayUsingPredicate:filter];

for (int i = 0; i < onlyImages.count; i++) {
    NSString *imagePath = [myPath stringByAppendingPathComponent:[onlyImages objectAtIndex:i]];
    UIImage *tempImage = [UIImage imageWithContentsOfFile:imagePath];
    // do something you want
}
