How to move resizableUIView from its corner in iOS?

I want to drag resizable UIView from its corner? Like on desktop we Click the mouse button and hold on click and drag the mouse then a transparent view is visible like this.

I want this in my Project in iPhone. I want when the user touch and drag the finger one resizable transparent view will visible.

I have done so far on click on button the view is visible and that is resizable also. But it is not my solution, I want on touch on any iphone screen the resizable UIView will come.

Any Idea and suggestions would be highly welcome.

This is my code what I have done so far:

- (void)viewDidLoad

tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
tap.numberOfTapsRequired = 1;
[imageVw addGestureRecognizer:tap];
pan=[[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(panAction:)];
[pan setMinimumNumberOfTouches:1];
[pan setMaximumNumberOfTouches:2];
[pan setDelegate:self];
//    [pan minimumNumberOfTouches:1];
//    [pan maximumNumberOfTouches:2];
[imageVw addGestureRecognizer:pan];

-(void)handleTap:(UIPanGestureRecognizer *)gestureRecognizer

userResizableView = [[SPUserResizableView alloc] init];
userResizableView.frame = CGRectMake(x,y,w,h);
//UIView *content_View = [[UIView alloc] initWithFrame:userResizableView.bounds];
//[content_View setBackgroundColor:[UIColor whiteColor]];
imageVw1 = [[UIImageView alloc]initWithFrame:userResizableView.bounds];
//imageVw1.image = [UIImage imageNamed:@"redacted2.jpg"];
imageVw1.backgroundColor = [UIColor blackColor];
imageVw1.autoresizesSubviews = YES;
imageVw1.alpha = 0.13;  // for opacity
userResizableView.contentView = imageVw1;
//[content_View addSubview:imageVw1];

//userResizableView.contentView = content_View;
userResizableView.delegate = self;
[userResizableView showEditingHandles];
currentlyEditingView = userResizableView;
lastEditedView = userResizableView;

// [self.view addSubview:userResizableView];
// [imageVw addSubview: dview];
[self.view addSubview: userResizableView];
[userResizableView release];


- (void)userResizableViewDidBeginEditing:(SPUserResizableView *)userResizableView1 {

 width  =   userResizableView.frame.size.width;
 height  =   userResizableView.frame.size.height;
 width1 = width;
 height1 = height;
 width = width + width;
 height = height + height;
[currentlyEditingView hideEditingHandles];
currentlyEditingView = userResizableView1;


- (void)userResizableViewDidEndEditing:(SPUserResizableView *)userResizableView1 {

lastEditedView = userResizableView1;
x1 = x;
y1 = y;
x =  userResizableView.frame.origin.x;
y = userResizableView.frame.origin.y;



First you have to declare two global variables

CGPoint startPoint;
BOOL _shouldResize;

Then you have to override two touch event methods in your view as given


- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

CGPoint touchPoint = [[touches anyObject] locationInView:[self superview]];


 Here you have to check user tap to the corner of your view by using the method
 CGRectContainsPoint(CGRect rect, touchPoint);

 Here the parameter rect should be the corner of your view

 if(!CGRectContainsPoint(CGRect rect, touchPoint)) { // Here user did not tap in your specific rect. so no need of resizing

    _shouldResize = NO;


_shouldResize = YES;

startPoint = touchPoint;



- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {


CGPoint touchPoint = [[touches anyObject] locationInView:[self superview]];

CGFloat displacementX = touchPoint.x - startPoint.x;
CGFloat displacementY = touchPoint.y - startPoint.y;

startPoint.x = touchPoint.x;
startPoint.y = touchPoint.y;

CGRect frame = [self frame];
frame.size.width += displacementX;
frame.size.height += displacementY;

[self setFrame:frame];


Hope this will help you :)
