    Write following code in .h file
    Add first the assets library framework from BuildPhase -> Link Binary with libraries
    import framework in .h

    AssetsLibrary/AssetsLibrary.h


    Declare properties

    @property (nonatomic, retain) ALAssetsGroup assetsGroup;
    @property (nonatomic,strong)NSMutableArray
    assetsArray;
    @property (nonatomic, retain) ALAssetsLibrary* assetLibrary;

    Write this code in .m file // Call this below mentioned function in your viewWillAppear
    -(void)getAllPictures
    {
    self.assetsArray = [[NSMutableArray alloc]init];
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    self.assetLibrary = library;
    NSMutableArray *groups = [NSMutableArray array];
    [assetLibrary enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
    if (group) {
    [groups addObject:group];
    } else {
    // this is the end
    [self displayPickerForGroup:[groups objectAtIndex:0]];
    }
    } failureBlock:^(NSError *error) {
    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[NSString stringWithFormat:@"Album Error: %@ - %@", [error localizedDescription], [error localizedRecoverySuggestion]] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show];

        NSLog(@"A problem occurred %@", [error description]);
        // an error here means that the asset groups were inaccessible.
        // Maybe the user or system preferences refused access.
    }];
    

    } //=========================================================================== - (void)displayPickerForGroup:(ALAssetsGroup *)group
