Re: [blacktechies] IOS tips & tricks?

From: Burton
Sent on: Thursday, August 7, 2014 11:51 AM
I've currently working on my second iOS application for the company that I work for.  I'm currently developing my app in Objectice C. This is probably an amateur hour comment but...  I found that in a lot of places that I expected to get back a nil reference for an object I was getting a reference to a NSNull object.  Thus I started to do a lot of checks to see if the object 'was a' NSNull object.  Therefore I created a static method to check to see if an object is null...

+(bool) isNull:(NSObject*) testObj{

    if(testObj == nil || [testObj isKindOfClass:[NSNull class]] ){

        return YES;


        return NO;



 You may or may not run into the same issue so...  Like I said amateur hour...

Hey Techies,

While I'm over here in Europe, I'm building my first iOS app. It's just a simple app to keep track of travel expenses between multiple people.

Anyone have tips or tricks learned through building apps? Like where corners can be cut and not?

Thank you,
