POSubclassed UIView with custom init - is this sane?
text
Body
copied!<p>I've been casting around looking for best-practices and whatnot for creating custom, reusable view components. So far, it seems like a custom UIView subclass is the way to go.</p> <p>In this case, all I need is a fixed-size view with easy access to a label, and a convenience initializer would be great. I could tag the label and use a constant, but it seems unnecessary given this (boilerplate like UIKit importing removed) (with ARC):</p> <pre><code>// .h file @interface MyView : UIView @property (nonatomic, weak) IBOutlet UILabel *label; + (id)withText:(NSString *)text; @end // .m file @implementation MyView + (id)withText:(NSString *)text { MyView *view = [[[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:nil options:nil] objectAtIndex:0]; view.label.text = text; return view; } @end </code></pre> <p>(edit: changed to class method. my concerns are still unchanged, though it's a bit less dubious overall)</p> <p>My MyView.xib file's only top-level element (a UIView) has a custom class set to MyView, and the outlet is hooked up to the FileOwner.</p> <p>And... this works. Perfectly. It renders correctly everywhere I'm using it, no exceptions, no clipping, no funny business at all that I can see.</p> <p>So far. I'm more than a little concerned that:</p> <ol> <li>I haven't seen this technique anywhere yet. Of course, I've only been looking for a relatively short time (a couple hours, passively).</li> <li>I'm not doing any of the recommended overriding of initWithFrame: / Coder: etc.</li> <li>I'm only using this in an extremely-limited realm right now, so it is nowhere <em>near</em> well tested for situations like the view going out of view, the drawing performance is unknown, I haven't checked thoroughly for memory leaks, etc.</li> <li>I'm almost certain I'm missing something. Most likely I'll find it shortly while using it more, but I may not find all of them.</li> </ol> <p>Does someone with more UIView experience than I have mind lending their brain for a bit? Is this a good idea? A horrifying "omg wtf are you thinking" idea? Are there surprises waiting for me? Is there something I should read for how to create simple custom views like this?</p>
