Move imageView in a specific frame!

[Franhu]

Hi all..

I want to move my UIImageView only across the half screen. So i need help to understand what's exactly going on in this lines of code.
Is it better to put the imageView in an UIView and then i can only move the UIImageView in my UIView? But i don't understand how i can fix it!
Can anybody explain me the code: touchInLocation:self.view?

Thanx a lot for helping!

// testtouchmovedViewController.h

#import <UIKit/UIKit.h>

@interface testtouchmovedViewController : UIViewController {
IBOutlet UIImageView *appleView;
}

@property (nonatomic,retain) UIImageView *appleView;

@end

// testtouchmovedViewController.m

- (void)touchesMovedNSSet *)touches withEventUIEvent *)event {

// get touch event
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self.view];

if ([touch view] == appleView) {
// move the image view
appleView.center = touchLocation;
}

}
