Question

I have the following class structure for custom UITableViewCells:

NumericEntryCell
– Contains method for controlling max value that can be entered into a textbox.

SliderCell
– inherits from NEC and contains methods for handling slider-control of textbox value

TextOnlyCell
– just contains a textbox

CellA
– inherits from SliderCell and has a max value of 28

CellB
– inherits from TextOnlyCell and has a max value of 150.

I want NumericEntryCell to contain a definition for a property that contains the maxValue. I want to be able to set a value for this in the initialize method of a child class (CellA or CellB).

Currently I have an int maxValue declared in the interface of NEC. I declare a property for this with @property int maxValue and @synthesize it within the .m file. However, attempting to modify this property’s value from CellA or CellB’s initialize method has no effect – when I hit a breakpoint in the NEC method that uses this value, its value is always zero. How can I get this to work?

Having read the comments to Paul’s answer, you might want to consider initialising your maxValue variable in -awakeFromNib. Objects in a nib are effectively already initialised and might be instantiated in the application using initWithCoder, not the designated initialiser.
