I have some functionality that I need in all my classes which derive from either UIView or UIImageView. More specifically, I have gesture related code that both these classes need. Currently my implementation is: UIGestureView : UIView UIGestureImageView : UIImageView and make all classes derive from these. These classes will again c...
I figured this one out, yet thought it worthy of its own question answer pair. I'm new to Xcode and Objective C, and getting to know its varied eccentricities. For instance, the compiler warning "warning: ''may not respond to '<[-|+]FUNCTION>'" appears when I try to compile the following code, which all appears in my implementation file...
I was wondering if anyone knew how iSimulate automatically registers/hooks itself into a debugged iDevice application? It's as simple as including the static library (and a couple of frameworks) and it just works. There are no methods or functions to call. How is this possible? ...

I display the child view using the presentModalViewController as below: ChildController *child = [[ChildController alloc[ initWithNibName:@"ChildView" bundle:nil]; [self pr...
I am attempting to build an FSM to control a timer in (iphone sdk) objective c. I felt it was a necessary step, because I was otherwise ending up with nasty spaghetti code containing pages of if-then statements. The complexity, non-readability, and difficulty of adding/changing features lead me to attempt a more formal solution like this...
I have a multiple XIB file project. I have a switchViewController class that handles the switching of content views. I want to call the methods in this class from other classes. I have the following code: //SwitchViewController.h Code: #import <UIKit/UIKit.h> @class MainMenuViewController; @class GlassRepairsViewController; @inter...

Is it possible to connect to Sql Server for the purpose of executing simple Sql commands within a native iPhone app? If so, how does one go about it? I'm stumped. More generally, I would at least like to see how this is done with GCC. Thanks in advance, Rich ...
UPDATE: I tried implementing the method specified by Peter and am getting incorrect shadowing. What is wrong? CGContextSetShadowWithColor(c, CGSizeMake(4, 4), kAudioThumbShadowBlur, [[UAColor blackColor] CGColor]); CGContextFillPath(c); CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, minx, mid...
So I have an app where you play a game, and at the end it asks you your name for recording of the high score. I would like to use a modal view to accomplish this, but I am experiencing some hiccups along the way. So far, all I have is the modal view sliding up all the way to the top of the screen, but there isn't anything there yet, it's...
Hi, I have derived from a 3rd party class, and when I attempt to call a method in the base class, I get the x may not respond to y compiler warning. How can I remove the warning? Repro: @interface ThirdPartyBaseClass : NSObject {} +(id)build; -(void)doStuff; @end @implementation ThirdPartyBaseClass +(id) build{ return [[[self al...
How do I arrange (in terms of depth) a view's subview to be in front of another view? The hierarchy looks like this: A-- -C -D B-- -E -F (A and B are views with C & D, and E & F, as subviews, respectively.) B is layered above A, so every subview in B (E and F) is above every subview in A (C and D). How can I make C displ...
Let's say I want to write a simple Cocoa app to make the Spaces feature of Leopard more useful. I would like to configure each space to have, say, different *screen resolutions *keyboard layouts *volume (for audio) So there are two parts to my question: 1) I suppose there are ways to modify these three things independently of Spaces, r...

I know that with objects that I've got: CGRect ppGoalFrame; LocalPlaySetup *localPlaySetup; and I can test if (localPlaySetup == nil) but if I attempt to test the CGRect with == nil or == NULL if (ppGoalFrame == nil) I get invalid operands to binary == (have 'CGRect' and 'void...
