IOS Easy Apps

IOS apllications are not much hard when we used to develop them.those are few small apps which i used to create.You can try them out by coping and pasying those codes to relavant classes.
 Animation
.h

#import <UIKit/UIKit.h>

    IBOutlet UIView *mover;
    IBOutlet UIView *grower;

@property(nonatomic,retain)UIView *changer;

-(IBAction)move;
-(IBAction)grow;
-(IBAction)change;
@end


.m
