问题 I am using a function to build my custom cell. the function used to create the cell is "makeMyList". The stepper I have successfully increments and decrements the itemQuantity textField. The trouble I am having comes with updating the "itemPrice" label. I want itemPrice.text to be quantity * price and update dynamically as the quantity either goes up or down dynamically. Could someone possibly help me with how to get this to happen? Thank you in advance! class MyListTableViewCell:

问题 I tried to do something like this in the viewDidLoad method: self.myStepper.value = 10.0; But it's not working. I've googled and googled and I can't find any answers to this. It seems so easy for a slider, but can you do it with a stepper as well? 回答1: Stepper values need to be within bounds of min and max, or like in the comments to your question they get pushed to either the min or max. Always check Apple's Reference docs. Reference: http://developer.apple.com/library/ios/#documentation

So to clarify i will show the "bad" code i am using: - (void)stepperOneChanged:(UIStepper*)stepperOne { BOOL PlusButtonPressed=NO; if(stepperOne.value>globalValue) { PlusButtonPressed =YES; } globalValue=stepperOne.value; ////do what you need to do with the PlusButtonPressed boolean } So what is the right way to do this?
