在UITableView的iOS文档目录中列出已保存的文件？ [英] List saved files in iOS documents directory in a UITableView?

问题描述

我已设置以下代码将文件保存到文档目录：

  NSLog（@保存文件。 ..）; 
 
 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]; 
 
 [操作setCompletionBlockWithSuccess：^（AFHTTPRequestOperation * operation，id responseObject）{
 NSLog（@成功下载文件到％@，路径）; 
}失败：^（AFHTTPRequestOperation *操作，NSError *错误）{
 NSLog（@错误：％@，错误）; 
}]; 
 
 [操作开始]; 
  

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，我想要一个UIWebView导航到该文件（所有离线）。

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？<这是我用来获取目录内容的方法。

   - （NSArray *）listFileAtPath：（NSString *）path 
 {
 // ----->列出所有文件< ----- // 
 NSLog（@列出所有文件）; 
 
 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]）; 
} 
返回directoryContent; 
} 
  

I have set up the following code to save a file to the documents directory:

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];

However, I wish to add each file to a UITableView when it is successfully saved. When the file in the UITableView is tapped, I'd like a UIWebView to navigate to that file (all offline).

Also - how can I just get the filename and ending such as "logo.png" instead of http://www.reddexuk.com/logo.png?

How can I do this?

解决方案

Here is the method I use to get the content of a directory.

-(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;
}
