    <p>I am trying to add a tap gesture from a subclassed UIImageView and then control the tap from the View Controller. I am not getting any compiling errors but "addSubview" is not displaying any image. How can make the UIImageView to be displayed?</p> <p>If I try to control the tap and pan gestures from the subclassed UIImageVIew I have no problems but I would like to control these functions from the View Controller</p> <p>Relevant code looks like this.</p> <p>UIImageView subclass　　　　</p> <pre><code>- (id)initWithCoder:(NSCoder *)aDecoder { self = [super initWithCoder:aDecoder]; if (self) { //self.userInteractionEnabled = YES; previewController = [[PreviewController alloc]init]; [previewController self]; [self addSubview:character]; // Tap Initialization code UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:(PreviewController *)self.previewController action:@selector(addCharacter:)]; [self addGestureRecognizer:tap]; self.userInteractionEnabled = YES; } return self; } </code></pre> <p>View Controller</p> <pre><code>- (void)addCharacter:(UITapGestureRecognizer *)t { NSLog(@"add character"); imageNSArray = [NSMutableArray array]; uiImg = [UIImage imageNamed:@"homer.png"]; CGPoint loc = [t locationInView:self.view]; character = [[UIImageView alloc] initWithImage:uiImg]; character.center = loc; [imageNSArray addObject:character]; //Locate the imageNSArray on frameImageView area only. [self.view addSubview:character]; UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panCharacter:)]; [self.character addGestureRecognizer:pan]; character.userInteractionEnabled = YES; } </code></pre>

    1. COYou use `- (id)initWithCoder:(NSCoder *)aDecoder` which may not get called when not loaded from xib. Also, if your `character` is not user interaction enabled, I think the tap gesture recognizer added will never get fired. Maybe you should try to add the recognizer on `character`.

    3. CO@zetachang I don't think userinteraction enabled should be a problem because when I run that code from the subclass then it displays and can manipulate the uiimageview. While debugging initWithCoder is being called

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
