InitWithFrame not executed if view is a property - iphone

Question

I have GraphicView class that inherits from UIView. Its initWithFrame method is:
#implementation GraphicsView
- (id)initWithFrame:(CGRect)frameRect
{
self = [super initWithFrame:frameRect];
// Create a ball 2D object in the upper left corner of the screen
// heading down and right
ball = [[Object2D alloc] init];
ball.position = [[Point2D alloc] initWithX:0.0 Y:0.0];
ball.vector = [[Vector2D alloc] initWithX:5.0 Y:4.0];
// Start a timer that will call the tick method of this class
// 30 times per second
timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/30.0)
target:self
selector:#selector(tick)
userInfo:nil
repeats:YES];
return self;
}
Using Interface Builder I've added a UIView (class = GraphicView) to ViewController.xib. And I've added GraphicView as a property:
#interface VoiceTest01ViewController : UIViewController {
IBOutlet GraphicsView *graphView;
}
#property (nonatomic, retain) IBOutlet GraphicsView *graphView;
- (IBAction)btnStartClicked:(id)sender;
- (IBAction)btnDrawTriangleClicked:(id)sender;
#end
But with this code doesn't work, I need to call [graphView initWithFrame:graphView.frame] to make it works.
- (void)viewDidLoad {
[super viewDidLoad];
isListening = NO;
aleatoryValue = 10.0f;
// Esto es necesario para inicializar la vista
[graphView initWithFrame:graphView.frame];
}
Am I doing well? Is there a better way to do that?
I don't know why initWitFrame is not called if I add GraphicView as a property.

Answer 1

initWithFrame is not called when loading from a NIB, it's initWithCoder instead.
If you may be using both loading from a NIB and programmatic creation, you should make a common method (initCommon maybe?) that you would call from both initWithFrame and initWithCoder.
Oh, and your init method is not using the recommended practices:
- (id)initWithFrame:(CGRect)frameRect
{
if (!(self = [super initWithFrame:frameRect]))
return nil;
// ...
}
You should always check the return value of [super init...].
