Custom UIPageControl

Hello,
This code is useful for creating your custom page control having different color.


#import <Foundation/Foundation.h>


@interface GrayPageControl : UIPageControl
{
    UIImage* activeImage;
    UIImage* inactiveImage;
}
@property(nonatomic, retain) UIImage* activeImage;
@property(nonatomic, retain) UIImage* inactiveImage;
@end


#import "GrayPageControl.h"


@implementation GrayPageControl
@synthesize activeImage;
@synthesize inactiveImage;

-(id) initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    activeImage = [UIImage imageNamed:@"active_page_image.png"];
    inactiveImage = [UIImage imageNamed:@"inactive_page_image.png"];
    return self;
}

-(void)updateDots
{
    for (int i = 0; i < [self.subviews count]; i++)
    {
        UIImageView* dot = [self.subviews objectAtIndex:i];
        if (i == self.currentPage)
            dot.image = activeImage;
        else
            dot.image = inactiveImage;
    }
}

-(void)setCurrentPage:(NSInteger)page
{
    [super setCurrentPage:page];
    [self updateDots];
}

@end

After creating these two files in your project you have to declare:
 IBOutlet UIPageControl *nameObject;
in which you want to use this control and then you have to set his class in .XIB file as "GrayPageControl".



If any one has query then place you it over here.

Thanks and Regards,
