CFDataRef imgData;
CGDataProviderRef imgDataProvider;
CGImageRef image1;
imgData = (CFDataRef)[array objectAtIndex:i];
    imgDataProvider = CGDataProviderCreateWithCFData (imgData);
    image1 = CGImageCreateWithPNGDataProvider(imgDataProvider, NULL, true, kCGRenderingIntentDefault);

Answer 1

This should work:

CFDataRef imgData;
CGDataProviderRef imgDataProvider;
CGImageRef image1;
imgData = (CFDataRef)[array objectAtIndex:i];
imgDataProvider = CGDataProviderCreateWithCFData (imgData);
CFRelease(imgData);
image1 = CGImageCreateWithPNGDataProvider(imgDataProvider, NULL, true, kCGRenderingIntentDefault);
CGDataProviderRelease(imgDataProvider);

Don't forget to use CGImageRelease(image1); after you are done with it.
