Hey guys!
Ok, I've been reading a bit and I'm kind of getting the hang of iPhone development. I've downloaded some sample codes to play around with so I can understand the feel of the interface and all other things.
I have a couple of questions:
When I download a sample app for XCode, I am not able to "build and run" it. The "build and run" button is disabled. Do you know why?
When I download a sample app's coding, I open it, and then open a new project for myself. I analyze the sample code's app, and then look at my almost blank canvas project. So, I start out with either appname.h or appname.m and start typing in the code from the sample app to my blank canvas. Say in the appname.m, I type out one line in that sample app onto my blank project. I build and run it, and it works fine.
Then, when I do a second line from the sample app and type exactly into mine, I get errors and warnings.
So my question is, is it ok if you get warnings and "failed's" since the whole application hasn't been put together yet?
And one more thing: what do all of the colors that are typed up mean? I know green is for comments, like the //This comment or /*This comment*/ Brown is for the imports like #import: "AppSample.h"
But I don't know what the blue, the purples, and black colors mean.
I really appreciate all the help. I am hoping to learn a bit more on my journey.
I apologize if I'll be annoying... I will be probably post here if I am absolutely stumped. Thanks!
