Question

I have got UIStepper in the piece of code which is generated using the latest tools(5.1). Now I wish to make this app available for the 4.3 versions. When I specify the deployment target as 4.3 and run the app in the 4.3 simulator it crashes at the part of setting a value to the stepper.

step.value = [[array objectAtIndex:Indexpath.row] doubleValue];

This value is not getting set.
