Visual UI Debugging

Sometimes you need to debug location of objects. This can be difficult, when those objects are transparent or have same color as the background.

How to Make Round Corners for UITableViewCell

Sometimes you need round border around one or more UITableViewCell. Or maybe a button look-a-like without going through the trouble of actually making one. Here's a quick way:

First of all, you MUST include QuartzCore header, else meet some interesting error notes:

#import <QuartzCore/QuartzCore.h>

Then add this code after your cell initialization routine, usually at cellForRowAtIndexPath:

CALayer *layer = cell.layer;
layer.borderColor = [[UIColor blueColor] CGColor];
layer.borderWidth = 3.0f;
layer.cornerRadius = 20.0f;

Like many things in iOS SDK, you get to a certain point with relative ease - and this is about it. If you want to have more control over your "bubble button" you either dig deep into Quartz sample code or implement something which looks same in a completely different way.

For example I replaced this (got a bit further with carefully positioned UIViews inside UITableViewCell) with hardcoded bitmaps and scaling them nicely.
