Answer 1

Create all buttons using “custombutton” class.set BOOL variable in that.

@interface CustomLabel : UIButton
{
  BOOL *is_level_completed;

}
@property (nonatomic, retain)BOOL *is_level_completed;

while creating buttons set btn.is_level_completed = NO;After completing every level set btn.is_level_completed = YES;After that check in viewwillappear and change image for completed levels.

to store the data

set tag value for buttons(like 1,2,3…) and while completing the level store the tag value in NSUserDefaults using the following code,

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setInteger:btn.tag forKey:@"Completed_level_no"];

in viewWillAppear get the completed level and change the images for buttons.
