How to access a class instance from another method - objective-c

Question

Here's my code:
#import "ViewController.h"
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(50.0, 50.0, 0, 0)];
[self.view addSubview:view1];
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [[event allTouches] anyObject];
if([touch.view isEqual:self]) {
CGPoint point = [[touches anyObject] locationInView:self];
NSLog(#"%#",NSStringFromCGPoint(point));
self.view1.center = point;
}
}
I want to be able to access the instance "view1" of the class "UIView" from the touchesMoved method.
Thanks in advance!

You can declare local variables as stated in the other answer. However, in my opinion its better to declare private properties in the anonymous category as below:
#import "ViewController.h"
#interface ViewController ()
#property (nonatomic, strong) UIView *view1; // declares view1 as a private property
#end
#implementation ViewController
#synthesize view1 = _view1;
- (void)viewDidLoad
{
[super viewDidLoad];
self.view1 = [[UIView alloc] initWithFrame:CGRectMake(50.0, 50.0, 0, 0)];
[self.view addSubview:self.view1];
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [[event allTouches] anyObject];
if([touch.view isEqual:self])
{
CGPoint point = [[touches anyObject] locationInView:self];
NSLog(#"%#",NSStringFromCGPoint(point));
self.view1.center = point;
}
}

You can make rect1 an instance variable by placing it in your .h file. You can do something like:
#interface tempViewController : UIViewController
{
myRect *rect1;
}
Then in your .m file you will not have to declare it again.
