我已经设置了以下代码来将文件保存到文档目录:

NSLog(@"Saving File...");

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.reddexuk.com/logo.png"]];
AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc] initWithRequest:request] autorelease];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"logo.png"];
operation.outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Successfully downloaded file to %@", path);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

[operation start];

但是，我希望在成功保存后将每个文件添加到 UITableView。当点击 UITableView 中的文件时，我希望 UIWebView 导航到该文件(全部脱机)。

另外 - 我怎样才能获得文件名和结尾，例如“logo.png”而不是 http://www.reddexuk.com/logo.png ?

我该怎么做？

最佳答案

这是我用来获取目录内容的方法。

-(NSArray *)listFileAtPath:(NSString *)path
{
    //-----> LIST ALL FILES <-----//
    NSLog(@"LISTING ALL FILES FOUND");

    int count;

    NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:NULL];
    for (count = 0; count < (int)[directoryContent count]; count++)
    {
        NSLog(@"File %d: %@", (count + 1), [directoryContent objectAtIndex:count]);
    }
    return directoryContent;
}
