Here there,

I have a custom UIView. This view acts as a activity indicator but as label above the UIActivityIndicatorView. In the init, I add a CAGradientLayer. I allocate and initialize it and insert it at index 0 as a sublayer of the UIView layer property. In my dealloc method was called, I received a message in the console:

- [CALayer release]: message sent to deallocated instance.

My code:

@interface LabelActivityIndicatorView ()
{
    UILabel *_label;
    UIActivityIndicatorView *_activityIndicatorView;
    CAGradientLayer *_gradientLayer;
}
@end

@implementation LabelActivityIndicatorView

//dealloc
- (void) dealloc
{
    [_label release];
    [_activityIndicatorView release];

    //even tried to remove the layer
    [_gradientLayer removeFromSuperLayer];
    [_gradientLayer release];

    [super dealloc];
}

// init
- (id) initWithFrame:(CGRect)frame
{
    if ( (self = [super initWithFrame:frame]) )
    {
        // init the label

        // init the gradient layer
        _gradientLayer = [[CAGradientLayer alloc] init];
        [_gradientLayer setBounds:[self bounds]];
        [_gradientLayer setPosition:CGPointMake(frame.size.width/2, frame.size.height/2)];

        [[self layer] insertSublayer:_gradientLayer atIndex:0];

        [[self layer] setNeedsDisplay];
    }
    return self;
}

@end

Anyone have any ideas. Since I'm allocating and initializing the gradient layer I'm responsible for releasing it. I should be able to alloc and init and assign to some ivar. Perhaps I should create a property with retain on it.

Thanks,
