    <p>UIImageView turns off userInteraction - turn it on and the button will work.</p> <p>EDIT:</p> <p>So I used your code almost exactly as written - the one red herring is that you said it all appears fine. For me, the custom button had a frame of 0,0,0,0 so I saw nothing. When I set the frame it all worked perfectly:</p> <pre><code> UIButton *back = [UIButton buttonWithType:UIButtonTypeCustom]; UIImage *image = [UIImage imageNamed:@"46-truck.png"]; assert(image); [back setImage:image forState:UIControlStateNormal]; [back addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside]; back.showsTouchWhenHighlighted = YES; back.frame = (CGRect){ {0,0}, image.size}; NSLog(@"FRAME: %@", NSStringFromCGRect(back.frame) ); [imageView addSubview:back]; </code></pre> <p>So, if you need to probe the superviews during run time to figure out what is what, you can use this code below. [UIView dumpSuperviews:back msg:@"Darn Bark Button"];</p> <pre><code>@interface UIView (Utilities_Private) + (void)appendView:(UIView *)v toStr:(NSMutableString *)str; @end @implementation UIView (Utilities_Private) + (void)appendView:(UIView *)a toStr:(NSMutableString *)str { [str appendFormat:@" %@: frame=%@ bounds=%@ layerFrame=%@ tag=%d userInteraction=%d alpha=%f hidden=%d\n", NSStringFromClass([a class]), NSStringFromCGRect(a.frame), NSStringFromCGRect(a.bounds), NSStringFromCGRect(a.layer.frame), a.tag, a.userInteractionEnabled, a.alpha, a.isHidden ]; } @end @implementation UIView (Utilities) + (void)dumpSuperviews:(UIView *)v msg:(NSString *)msg { NSMutableString *str = [NSMutableString stringWithCapacity:256]; while(v) { [self appendView:v toStr:str]; v = v.superview; } [str appendString:@"\n"]; NSLog(@"%@:\n%@", msg, str); } + (void)dumpSubviews:(UIView *)v msg:(NSString *)msg { NSMutableString *str = [NSMutableString stringWithCapacity:256]; if(v) [self appendView:v toStr:str]; for(UIView *a in v.subviews) { [self appendView:a toStr:str]; } [str appendString:@"\n"]; NSLog(@"%@:\n%@", msg, str); } @end </code></pre>

    1. COIf you read the code and the last part of the question, he has it enabled. **`left.userInteractionEnabled = YES;`**

    2. COAh yes, I jumped to conclusions and did not see that line :-(. Its just so common. Anyway, does the parent view have userInteractionEnabled? I have never added a button to a imageView, but I have added a gesture recognizer.

    3. COI have set the frames properly in another method that I use to set frames for all views in the screen. So it appears at the proper frame as well.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
