iOS: DrawRect does not move my view - ios

Question

I’m a new developer on iOS and I’m struggling with the DrawRect method: the first time it gets called, it actually draws what I want where I want, but all the next calls to DrawRect fail to move my view (although they do resize it).
I therefore made a minimalist test app to reproduce my problem but still could not isolate the cause.
This app just draws a blue rectangle in the top left corner, and each time you tap into it, it’s supposed to:
Switch width and height (this does work)
Move the rectangle by 10 points to the right (this does not work)
Of course I checked that DrawRect actually gets called and that its bounds did change to what I wanted, but still, my view does not want to move.
==============================================
Here’s my ViewController (RVTViewController.m)
==============================================
#implementation RVTViewController
(void)viewDidLoad`
{
[super viewDidLoad];
if (!self.myView)
{
CGRect viewBounds = CGRectMake(0,0,100,150);
self.myView = [[RVTView alloc] initWithFrame:viewBounds];
[self.view addSubview:self.myView];
UITapGestureRecognizer* gestRec = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tap:)];
[self.myView addGestureRecognizer:gestRec];
}
}
-(void) tap:(UITapGestureRecognizer*) gesture
{
CGRect newViewBounds = CGRectMake(self.myView.bounds.origin.x + 10,
self.myView.bounds.origin.y,
self.myView.bounds.size.height,
self.myView.bounds.size.width);
self.myView.bounds = newViewBounds;
[self.myView setNeedsLayout];
[self.myView setNeedsDisplay];
}
#end
=====================================
And here’s my custom view (RVTView.m)
=====================================
#implementation RVTView
- (void)drawRect:(CGRect)rect
{
CGRect newBounds = self.bounds;
UIBezierPath* newRect = [UIBezierPath bezierPathWithRect:newBounds];
[[UIColor blueColor] setFill];
UIRectFill(self.bounds);
[newRect stroke];
}
#end
Can someone please tell me what I am getting wrong ?

Answer 1

Using [self.myView setFrame:newViewBounds]; instead of self.myView.bounds = newViewBounds; fixed the problem.
