Hi there. Basically I've got the same background image throughout my entire iphone application. I don't use XIBs (nasty things :p). So I was wondering if there was any way to add a "default" background image to all of my UIViewControllers? I tried subclassing UIViewController and created the class UIViewControllerWithDefaultBackgroun...
Anyone who has gone through the Stanford CS193P class on iTunes will recognize this from Assignment 3 (HelloPoly). For those not familiar: I have a custom view called polyView, an instance of PolygonView, a subclass of UIView. On this view, I use CGContextDrawLinearGradient to paint a color gradient over the entire rectangular view. T...
The following animates a view to the upper left part of the screen (ipad): [UIView beginAnimations:@"anim" context:nil]; [UIView setAnimationDuration:5]; [UIView setAnimationDelegate:self]; someView.frame = CGRectMake(0, 0, 1024, 768); [UIView commitAnimations]; However, it does not resize the view (think of a UIImageView that I w...
How do I capture touch events such as - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event without subclassing a UIView nor using UIViewControllers. What happens is that I have a simple UIView created programmatically and I need to detect basic tap events. ...
Hi. I have 2 points in a UIView, but I am unable to get the correct line equation between these two points because UIView coordinate system is not cartesian. When I apply the cartesian slope of a line, I keep getting the wrong slope for the UIView coordinate system. Maybe I'm applying the identity matrix incorrectly or using the wrong id...

I have a UIView subclass called Card that I move around on my board and drop on hot spots called slots. When I drop the card I use the hitTest to figure out if I am dropping the card on one of my hotspots. I want to get a property of that hot spot but I am having trouble getting that to work properly. My only guess is the hitTest return...

in my previous code, I changed the coordinate system in my view's drawRect, so that the rectangle had 0,0 in the centre, 0,1 at the top centre and 1,0 in the centre of the right edge. I.e. a normalised Cartesian system. { // SCALE so that we range from TL(0, 0) - BR(2, -2) CGContextScaleCTM (X, 0.5 * bitmapSize.width, -...
I need to know if a point is inside at lease one of the views in a given set of views. For that, I used UIView's pointInView method, but it always returns NO. As an act of despair, I checked if the view's center point is inside the view and it also returned NO. This is the code I've used for that: BOOL wasPointFound = NO; NSArray *views...
