Learn Xcode 4 Tutorial iOS iPad iPhone 1.5 Implementing Methods Actions

[Bigrock241]

Hello,

Thanks in advance for any help.

OK....I'm on Xcode 4 Tutorial 1/5 Implementing Methods Actions (Briner)...built then Run....get a "Build Succeeded"....iPad Simulator opens....and blank Simulator screen!!! Anyone?

I am getting this message in the debugger: 2012-01-12 16:59:40.876 bringer[614:f803] Applications are expected to have a root view controller at the end of application launch

I'm on Xcode 4.2, SDK 5.0 and Lion.

Finding these tutorials really helpful. Thanks.

@rayry7 Yeah I have the same problem. Did you ever find out how to fix that?

1lucky43,

I rebuilt the program and it ran just fine...still have no idea why!! Might have had something to do with SIGABRT.....can someone please explain that one to me (in layman's terms.)

I'm going to create a list, and then I want a send button. The send button is going to send the list to an email. How do I do this?

I double checked my code and no errors appear but when I run the simulator it just shows a white screen. Any ideas?

I would like to build an app with just text and photos. Do I use a "View" and place all my text and photos in a "text view" folded. Also I want it to be uneditable so how do I stop the typewriter from from coming up?

Yay, got it working, exactly like yours.

I suppose the obvious question for n00bs like me is "how do you learn this stuff?" How do you know what code to write and where? It's one thing to follow a tutorial and just copy what someone else is doing, but knowing how to use these instructions is quite something else.

The interface designer is easy enough, and I understand the logic of what you're doing, but how did you learn that other stuff? The actual syntax and commands?

@betchaboy hi, the iphone uses the "objective c" programming language. there are many tutorials for how to learn this, plus I think he said he would be going into in future videos if that helps. it is basically the c language, but the part that implements what is called object oriented programming, is from the next step language. but for that language, I think most people will learn how to build a project like this from tutorials, but most are not as good as this or in video!

Keep these AMAZING tutorials coming!

You should point out little things like float is used for numbers with decimals.

the @interface is like your blue print... and your @implementation is where you add the instructions for the methods we stated on our @interface... in other words be more descriptive you were very good describing xcode but not so good with the coding and the coding is what matters.
