Please name your variables starting with a lowercase. Don't use multiple arrays for values that are synce'd. Instead parse the dictionary into a custom class. Also what isstrimage? Is that an URL? Is that Base64Image data?

This is how you should do it:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
NSURL* url = [NSURL URLWithString:SCImageArr[indexPath.row]];
NSData* data = [NSData dataWithContentsOfURL:url];
UIImage* image = [UIImage imageWithData:data];
dispatch_async(dispatch_get_main_queue(), ^{
cell.categoriesImages.image = image;
});
});
Also: it has no relation to the question, but don't give variables capitalized names
