Comment on Create A Custom UINavigationBar Style by Angel

I love this topic! Many people saying that method swizziling is dangerous but I will argue that the only thing dangerous there is doing it without the correct knowledge and runtime checks. We have shipped apps with this without problems, and of course that it could stop working on some new iOS (specially if you are swizzingling private APIs), but almost every solution eventually will do and with the proper checks no crashes should happen.
Furthermore, subclassing in this case is not an option because it is the navigationBar the one that draws but it is instantiated and managed by the navigationcontroller (readonly).
A category overriden the draw method is as dangerous as the method swizziling (it can also stop working properly with new iOS) and you lose the original implementation of the drawRect! not an option if you need the default look and feel in some bars and a very bad decision in terms of code reuse!

In theses cases, I think that method swizzling is a great approach, but of course you have to be very careful about what you are doing and sanitize it properly.

Anyway, I want to add another different way to achieve the same results without the method swizziling: http://sebastiancelis.com/2012/03/05/subclassing-hard-to-reach-classes/

Good article!
Cheers!

Hi Devin, great post. Do you have any more details on the beta testing use of Mail Chimp?

Have you done another post on the subject?

Any links to share? I just sign up on MC to do it this way. I think it’s a great idea.

Great job!

Wy would you buy a Ferrari if you can’t drive one? As a developer, you must assume the risks that you take, and decide what is better for your project. If you’re changing the behavior of a Apple (or someone else) component, they are in charge of allow or not it. Write good code, that works, and make incredible things. Is that what counts.

Comment on I’m the first to admit… by Daron Jones

Hey Devin,

Nice site!! I think I’ve been here before whilst it was under a different look (that I dont remember), however this is pretty slick.

I found my way (back) here because of an app im working on at the moment.

Whist gazing at calendar app’s calendar view and thinking how to recreate something like it, I decided that I’d take a look around. I and found your Takpu implementation and Kal.

I’d like try your version. The installation instructions with the screenshots and the notice about not dragging to avoid xcode 4 errors gives me more confidence that it will work without problems.

However, I’m a little hesitant for a couple reasons:

First, like you I haven’t spent much quality time with contracts. Legal jargon makes me a little jumpy; And second whilst reading the apache license included with your source, it stated that I can use your source under the conditions that I retained the copyright notice and the license.

You didn’t however add a copyright notice so I’m not sure that the license is effective.

Ironically, I came across this post you’d left whilst exploring ways back from github to contact you

I’d like to ask you to add a copyright notice like you’ve done to this site to your source. Pleeeeease – it will help me quieten nerve…
