ImageGallery image in black for ios 7 - iphone

Question

In my efforts to upgrade my application to support IOS7 I found out that ImageGallery don't load the images. in others iOS is ok.
In imageGalleryView:
- (void)initWithPhotos:(NSMutableArray *)photoURLStrings andCaptions:(NSArray *)myCaptions moveToPage:(int)page {
captions = [myCaptions copy];
photoUrls = [photoURLStrings copy];
NSLog(#"array---> %#", photoUrls);
photoLoaded = [[NSMutableArray alloc] init];
for (int i=0; i<[photoURLStrings count]; i++) {
[photoLoaded addObject:[NSNumber numberWithBool:FALSE]];
}
[pageControl setNumberOfPages:[photoUrls count]];
//scrollView= [[UIScrollView alloc] init];
scrollView.backgroundColor = [UIColor blackColor];
scrollView.pagingEnabled = TRUE;
scrollView.autoresizesSubviews = TRUE;
scrollView.contentSize = CGSizeMake(320 * [photoUrls count], scrollView.frame.size.height);
scrollView.contentOffset = CGPointMake(self.scrollView.frame.size.width*page, 0);
if (([captions objectAtIndex:page] == nil) || ([[captions objectAtIndex:page] isEqualToString:#""])) {
[textView setHidden:TRUE];
} else {
[textView setHidden:FALSE];
[textView setText:[captions objectAtIndex:page]];
}
[self showImages:page];}
- (void)showImages:(int)page {
AsyncImageViewController *asyncImageView;
if ((page>=0)&&(page<[photoUrls count])) {
if (![[photoLoaded objectAtIndex:page] boolValue]) {
[photoLoaded replaceObjectAtIndex:page withObject:[NSNumber numberWithBool:TRUE]];
asyncImageView = [[AsyncImageViewController alloc] init];
//NSLog(#"%#",[NSString stringWithFormat:#"%#",[photoUrls objectAtIndex:page]]);
[asyncImageView loadImageFromURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#",[photoUrls objectAtIndex:page]]] pos:1];
//NSLog(#"page:%i",page);
asyncImageView.frame = CGRectMake(320*page,0,320,scrollView.frame.size.height);
//[scrollView setBackgroundColor:[UIColor colorWithPatternImage:asyncImageView.image]];
[scrollView addSubview:asyncImageView];
[asyncImageView release];
}
}
page = page - 1;
if ((page>=0)&&(page<[photoUrls count])) {
if (![[photoLoaded objectAtIndex:page] boolValue]) {
[photoLoaded replaceObjectAtIndex:page withObject:[NSNumber numberWithBool:TRUE]];
asyncImageView = [[AsyncImageViewController alloc] init];
[asyncImageView loadImageFromURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#",[photoUrls objectAtIndex:page]]] pos:1];
asyncImageView.frame = CGRectMake(320*page,0,320,scrollView.frame.size.height);
[scrollView addSubview:asyncImageView];
[asyncImageView release];
}
}
page = page + 2;
if ((page>=0)&&(page<[photoUrls count])) {
if (![[photoLoaded objectAtIndex:page] boolValue]) {
[photoLoaded replaceObjectAtIndex:page withObject:[NSNumber numberWithBool:TRUE]];
asyncImageView = [[AsyncImageViewController alloc] init];
[asyncImageView loadImageFromURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#",[photoUrls objectAtIndex:page]]] pos:1];
asyncImageView.frame = CGRectMake(320*page,0,320,scrollView.frame.size.height);
[scrollView addSubview:asyncImageView];
//[scrollView setBackgroundColor:[UIColor colorWithPatternImage:asyncImageView.image]];
[asyncImageView release];}}}
In the asyncimageview:
- (void)loadImageFromURL:(NSURL*)url pos:(int) posicio {
if (connection!=nil) { [connection release]; }
if (data!=nil) { [data release]; }
NSURLRequest* request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
loading = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
if (posicio == 0) {
loading.center = CGPointMake(75/2,75/2);
}else {
loading.center = CGPointMake(160,210);
}
[loading startAnimating];
[self addSubview:loading];
[loading release];}//the URL connection calls this repeatedly as data arrives- (void)connection:(NSURLConnection *)theConnection didReceiveData:(NSData *)incrementalData {
if (data==nil) { data = [[NSMutableData alloc] initWithCapacity:2048]; }
[data appendData:incrementalData];}//the URL connection calls this once all the data has downloaded- (void)connectionDidFinishLoading:(NSURLConnection*)theConnection {
//so self data now has the complete image
[connection release];
connection=nil;
if ([[self subviews] count]>0) {
//then this must be another image, the old one is still in subviews
[[[self subviews] objectAtIndex:0] removeFromSuperview]; //so remove it (releases it also)
}//make an image view for the image
imageView = [[[UIImageView alloc] initWithImage:[UIImage imageWithData:data]] autorelease];
//make sizing choices based on your needs, experiment with these. maybe not all the calls below are needed.
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.autoresizingMask = ( UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight );
//[self setBackgroundColor:[UIColor colorWithPatternImage:imageView]];
[self addSubview:imageView];
imageView.frame = self.bounds;
[imageView setNeedsLayout];
[self setNeedsLayout];
[loading stopAnimating];
[data release]; //don't need this any more, its in the UIImageView now
data=nil;}
//just in case you want to get the image directly, here it is in subviews- (UIImage*) image {
UIImageView* iv = [[self subviews] objectAtIndex:0];
return [iv image];}
I checked all and saw that it is UIView instead of UIImageView. probably Apple changed something. But xCode don't throw any errors.
Any idea how to fix it?
