  1. POTrying to reuse variable to avoid abandoned memory
    text
    copied!<p>I've got a TapDetectingImageView class that is pertaining in memory after usage because I do not reuse it in my code. I change my code now to reuse it instead of re creating a new one each time.</p> <p>The goal is to configure that TapDetectingImageView object and put it in a view. I'll do it 8 times but with the code below, only the last one is showing. I'm sure I'm missing something, but what? ;)</p> <p>The view holding the imageViews is potatoeView. I'm adding new TapDetectingImageView through:</p> <pre><code>[potatoeView addSubview:imageView]; </code></pre> <p>What's wrong in that code?</p> <pre><code>for (int i = 0; i &lt;= numberOfPotatoes-1; i++) { NSLog(@"potatoesView Generation : %d",i); NSArray *imgArray = [[NSArray alloc] initWithArray:[p objectAtIndex:i]]; UIImage *img1 = (UIImage *) [imgArray objectAtIndex:0]; UIImage *img2 = (UIImage *) [imgArray objectAtIndex:1]; NSString *imgName = (NSString *) [imgArray objectAtIndex:2]; if (imageView == nil) { imageView = [[TapDetectingImageView alloc] initWithImage:img1 imageHighlighted:img2]; }else { [imageView setImage:(UIImage *)img1]; [imageView setImageHighlighted:(UIImage *)img2]; } [imageView setDelegate:self]; // setup each frame to a default height and width, it will be properly placed when we call "updateScrollList" CGRect rect = imageView.frame; rect.size.height = [potatoesSize floatValue] ; rect.size.width = [potatoesSize floatValue] ; imageView.frame = rect; [imageView setName:(NSString *)imgName]; imageView.tag = i+1; // tag our images for later use when we place them in serial fashion NSValue *val = [potatoesSizeAndPositions objectAtIndex:i]; CGPoint point = [val CGPointValue]; imageView.center = point; [potatoeView addSubview:imageView]; [imgArray release]; } </code></pre>
