error occurs at second run
<p>Im developing a little navigation based application. Part of the programe, It passes CGpoint value to its superclass. There is no problem on the first attempt but error always occurs when re run the same process right after first execution. Is this because about memory management? I just dont get what I have done wrong.</p>

<p>delegation from child</p>

<pre><code>[self.delegate sendPosition:position];
</code></pre>

<p>method on Rootclass</p>

<pre><code>-(void) sendPosition:(CGPoint)position{

        dLabel.text = [NSString stringWithFormat:@"%f",position.x];
}
</code></pre>
