Hi, I'm getting images from UIGetScreenImage() and storing directly in mutable array like:-

image = [UIImage imageWithScreenContents]; [array addObject:image]; [image release];

I've set this code in timer so I cant use UIImagePNGRepresentation() to store as NSData as it reduces the performance. I want to use this array directly after sometime i.e after capturing 1000 images in 100 seconds. When I use the code below:-

UIImage *im = [[UIImage alloc] init]; im = [array objectAtIndex:i]; UIImageWriteToSavedPhotosAlbum(im, nil, nil, nil);

the application crashes. And I dont want to use UIImagePNG or JPGRepresentation() in timer as it reduces performance.

My problem is how to use this array so that it is converted into image. If anybody has idea related to it please share with me. Thanks in Advance.
