With regards to the question you mention I think you've made it as reasonable and answerable as it can be. It's not that big a question, so I don't see what else would significantly improve it. I made a minor edit removing some fluff, but that's about it.
As for your remaining questions, keep an eye out on what you're exactly asking. You're a fairly active user on SO these last couple of days, predominantly answering questions. But perhaps you're moving a bit too fast. Take your time to get a decent grasp on what this site is about.
Make sure you understand what a good on-topic question looks like. If you don't, read the FAQ linked at the top. That might sound a bit petty, but I mean it. I have a look through it every now and then to see what it says, especially when reviewing/moderating.
Two of your questions had titles starting with:
- "What is the easiest way to..."
- "What are some good resources to..."
Without going into the particular details of those questions, their titles already raise alarm bells when it comes to their appropriateness for the site.
Asking for an "easiest way to" pretty much sounds non-constructive. Even if your question does not end up being not constructive, avoid such titles. Don't ask us for the "best/easiest way to". Simply state what your problem is, what you have done to solve it, where you failed and then ask how it can be solved. You can then evaluate the answers you get to see if one of them is easier/better than the other.
And don't ask for "good resources". We don't want to point you at resources other than this site where you might possibly find information on how to solve your problem. We want to be the site where people can find information on how to solve your problem.
Now, in this particular case you asked us for good resources on how to learn Objective-C. That is pretty much the definition of an off-topic question. We don't do such recommendations here. Have a read through the books tag-wiki for some information on this.
That said, looking through your other contributions you seem to write well, and you should have no problem formulating good questions, once you realize what is and what isn't appropriate for the site. So take your time to figure this out, improve your content where possible, contribute great answers and you should be able to get back on track.
