How to display all images from the NSDocument directory

First, I selected the images from the photo library to the ALAsset library, after which I saved the images in the document directory from the ALAsset library path.

I use this code to store images in the document catalog from the ALAsset library .... Its working fine ... Now I want to display all the images that are stored in the document catalog as a table. How can i do this??? can someone help me?

Code for importing images from ALAsset to the NSdocument directory

for (int j=0; j<[assetArray count]; j++) {

ALAssetRepresentation *representation = [[assetArray objectAtIndex:j] defaultRepresentation];
NSString* filename = [documentPath stringByAppendingPathComponent:[representation filename]];

[[NSFileManager defaultManager] createFileAtPath:filename contents:nil attributes:nil];
NSOutputStream *outPutStream = [NSOutputStream outputStreamToFileAtPath:filename append:YES];
[outPutStream open];

long long offset = 0;
long long bytesRead = 0;

NSError *error;
uint8_t * buffer = malloc(131072);
while (offset<[representation size] && [outPutStream hasSpaceAvailable]) {
    bytesRead = [representation getBytes:buffer fromOffset:offset length:131072 error:&error];
    [outPutStream write:buffer maxLength:bytesRead];
    offset = offset+bytesRead;
}
[outPutStream close];
free(buffer);

}

After that, I got the contents of the directory using this code:

 NSFileManager *manager = [NSFileManager defaultManager];
fileList = [manager directoryContentsAtPath:newDir];

It also works ... but now that I want to display images from the document catalog. He does not show anything ....

 setImage.image=[UIImage imageNamed:[filePathsArray objectAtIndex:0]];

- , ?????  - : * ALAsset ?

-(void)viewWillAppear:(BOOL)animated
{

    arrayOfImages = [[NSMutableArray alloc]init];
NSError *error = nil;


    NSString *stringPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];

    NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath: stringPath  error:&error];

  for(int i=0;i<[filePathsArray count];i++)
  {
      NSString *strFilePath = [filePathsArray objectAtIndex:i];
      if ([[strFilePath pathExtension] isEqualToString:@"jpg"] || [[strFilePath pathExtension] isEqualToString:@"png"] || [[strFilePath pathExtension] isEqualToString:@"PNG"]) 
      {
         NSString *imagePath = [[stringPath stringByAppendingString:@"/"] stringByAppendingString:strFilePath];
         NSData *data = [NSData dataWithContentsOfFile:imagePath];
        if(data)
        {
          UIImage *image = [UIImage imageWithData:data];
          [arrayOfImages addObject:image];
        }
      }

  }

#pragma mark - UItableViewDelegate methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [arrayOfImages count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tablView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell == nil)
    {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }
    //adjust your imageview frame according to you
    UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0.0, 0.0, 470.0, 80.0)];

    [imageView setImage:[arrayOfImages objectAtIndex:indexPath.row]];
    [cell.contentView addSubview:imageView];
    return cell;

:

NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject] error:NULL];

:

[imgView setImage:[UIImage imageWithContentsOfFile:"Your complete path"]];
+4

:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];

    NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory  error:nil];
    NSMutableArray *imgFiles = [[NSMutableArray alloc] init];
    for (int i=0; i<filePathsArray.count; i++) {
        NSString *strFilePath = [filePathsArray objectAtIndex:0];
        if ([[strFilePath pathExtension] isEqualToString:@"jpg"]) {
            [imgFiles addObject:[filePathsArray objectAtIndex:i]];
        }
    }

    NSLog(@"array with paths of image files in the Document Directory %@", filePathsArray);

And then you can display the images UITableViewas follows:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(5, 5, 50, 50)];
    img.image = [UIImage imageWithContentsOfFile:[imgFiles objectAtIndex:indexPath.row]];
    [cell addSubview:img];

    return cell;
}

Hooray!!!
