Question

I’m doing the following in my App right now:

NSInteger myReell1 = 6;
NSInteger myReell2 = 7;
NSInteger myImag1  = -5;
NSInteger myImag2  = 3

+ (WSData *)scientificData 
{

float dataSet2D[2] = {0,myReell1 + myReell2};
float dataSet3D[2] = {0,myImag1 + myImag2};

return [WSData dataWithValues:[WSData arrayWithFloat:dataSet2D len:2]
                      valuesX:[WSData arrayWithFloat:dataSet3D len:2]];

}

This worked fine for me up to now.
Here is what I would like to change and what I would like to ask you for:

I would like to use 4 UITextFields to give the opportunity of personal input to the user, instead of the consistent Integers (myReell1, … ,myImag2) which I use right now.

How would you implement those UITextfields (maybe just 1 example?) into the code above to make the NSInteger part needless.

Please don’t mind about the actual stuff inside of the scientific data. 😉

Answer 1

Presuming this code is inside a view controller, you can:

1. Create your UITextField member variables in the class.
2. Subscribe the class to UITextFieldDelegate.
3. Wire your text fields up in Interface Builder (or instantiate them programatically and add them to the view).
4. Implement the didFinishEditing delegate method to handle the
   actual input.
