In this application we are going to create slider by using Window based application. There is  .h and  .m file.  We are going to add Slider to Window. 

Create a new project by selecting Window-Based Application.Open the Interface Builder by double clicking the MainWindow.xib file and add a Slider  and label from the library. label is used to display the value of slider.  
here we are declaring Slider as mslider(its a variable) using UISlider. It looks like this

IBOutlet UISlider *mswitch;

IBOutlet UILabel *labelTxt;

and property is defined for labelTxt

@property (nonatomic, retain) UILabel *labelTxt;

we are writing the action on button i.e.

-(IBAction)changeSlider:(id)sender   ;

To set slider max. and min value sellect slider and then tools and inspector

 

SliderAppDelegate.h file will look like this:

#import <UIKit/UIKit.h>

IBOutlet UISlider *slider;

IBOutlet UILabel *labelTxt;



}



@property (nonatomic, retain) IBOutlet UIWindow *window;

@property (nonatomic, retain) UILabel *labelTxt;

-(IBAction)changeSlider:(id)sender ;

#import "SliderAppDelegate.h"



@implementation SliderAppDelegate

@synthesize window,labelTxt ;

[window makeKeyAndVisible];

}

-(IBAction)changeSlider:(id)sender 

{

labelTxt .text= [[NSString alloc] initWithFormat:@"

}



- (void)dealloc

{

[window release];

[label.Txt release];

[super dealloc];

}
