Authors

A simple validator/equation answerer. Could be used to prevent spam (an extra form step) or prevent users from making stupid decisions at stupid times, when they are not thinking clearly, and can’t do simple math.

Installation

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like AFNetworking in your projects. See the "Getting Started" guide for more information.

Podfile

platform :ios, '7.0'
pod "RFMathTextField", "~> 1.3"

Installation without CocoaPods

Just drag the RFMathTextField folder into your project and import it.

#import 'RFMathTextField.h'

Use

RFMathTextField is very simple to install and use. Just init the RFMathTextField with or without a notification*, and choose from one of the 4 types (RFMathTextFieldEquationTypes) of equations:

  • RFMathTextFieldEquationTypeAddition
  • RFMathTextFieldEquationTypeSubtraction
  • RFMathTextFieldEquationTypeMultiplication
  • RFMathTextFieldEquationTypeRandom
RFMathTextField *textField = [[RFMathTextField alloc] initWithFrame:CGRectMake(20, 100, 180, 31)
                                           withEquation:RFMathTextFieldEquationTypeAddition 

* If you initialize RFMathTextField with a notification, remmber to add an observer with the same name.

That’s really it, just add an observer if you’re using notifications, so you can perform an action when the correct answer is input.

You can also always grab the answer to the equation (NSInteger equationAnswer) or if the answer is correct (BOOL answerCorrect).

Also, you can refresh the equation easily by calling

[textField refreshEquation];

Hope you enjoy it!
