Use as below for images

+ (UIImage *)pageControlColorWithIndex:(NSUInteger)index {
    if (__pageControlColorList == nil) {
        __pageControlColorList = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"imageforPage1.png"], [UIImage imageNamed:@"imageforPage2.png"],[UIImage imageNamed:@"imageforPage3.png"], [UIImage imageNamed:@"imageforPage4.png"], [UIImage imageNamed:@"imageforPage5.png"], [UIImage imageNamed:@"imageforPage6.png"], [UIImage imageNamed:@"imageforPage7.png"], nil];
    }
     //Check whether the **index** supply by you fall within the limit of Image array.
    if(index <  [__pageControlColorList count])
    {
       return [__pageControlColorList objectAtIndex:index % [__pageControlColorList count]];
    }
    else 
    {
       //If the **index** doesn't fall within the limit the Image array then return a default image
       return [UIImage imageNamed:@"defaultImageforPages.png"];
    }
}
