iOS - Accelerometer - iOS (iPhone, iPad) Tutorial

iOS - Accelerometer

Accelerometer is used for discovering the changes in the place of the product in the three guidelines x, y and z. We can know the present place of the product comparative to the floor. For examining this example, you'll need to run it on a system and to does not perform properly on simulation.

Accelerometer – Steps Involved

Step 1. Create a simple View based application.

Step 2. Add three labels in ViewController.xib and create ibOutlets naming them as xlabel, ylabel, and zlabel.

Step 3. Update ViewController.h as follows −

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController<UIAccelerometerDelegate>
{
    IBOutlet UILabel *xlabel;
    IBOutlet UILabel *ylabel;
    IBOutlet UILabel *zlabel;

}
@end

Step 4. Update ViewController.m as follows −

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[UIAccelerometer sharedAccelerometer]setDelegate:self];
    //Do any additional setup after loading the view,typically from a nib
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:
  (UIAcceleration *)acceleration{
    [xlabel setText:[NSString stringWithFormat:@"%f",acceleration.x]];
    [ylabel setText:[NSString stringWithFormat:@"%f",acceleration.y]];
    [zlabel setText:[NSString stringWithFormat:@"%f",acceleration.z]];
}

@end

Output

When we run the application in iPhone device, we'll get the following output −
