A little help? (xCode and Obj C)
Im getting started with xcode and objective-c.
I did 1st year at uni doing programming but I left after the first year. I wasnt very good and it was a while ago...but I thought it would be fun to give some programming a go again.
If I add to variables together... previousNumber and currentNumber, both declared as floats.
Say previousNumber is 6 and current is 0.1, and i display the answer in a textfield created with the xcode interface builder. I'm get 6.10000 and then a load of numbers.
Is this because I have to limit the amount of characters displayed? How would I do that?
Also when I build an app which is to be bootable on another machine how do I do that. I build the project. Theres an app in the build folder but I guess it needs some of the other files in there.
Thanks in advance

float aFloat = previousNumber + current; [aTextField setStringValue:[NSString stringWithFormat:@"%.1f", aFloat]];

Is that at outlets section in the header file?
Also, if I have a function. I have problems if Im using int and float together.
ie if I multiply the float variable by the int variable and use retval (which I set as a float) it only returns the whole number, not the decimal part.
Thanks again for the help guys.
I've tried as a project to make a calculator, which isnt as easy as i thought. It works fine apart from inputing decimals. The codes ugly though.......
I'm going to try getting dictionarys to work next.! I want different dictionaries in an array. I find it quite difficult, especially the memory management side. Though theres a nice tutorial about making an address book at the o'reilly site where he does just that though.

There must be something else that causes it. Try to log the different variables at different stages, watch what happens in the debugger or post the method/function here for someone to look at.
Someone get Nekkid™, now!
