uitextfield-delegationblocks's Introduction

UITextField+DelegationBlocks

A simple category that allows you to add completion blocks for your UITextField on a per instance basis. What this means is that you can do something like this:

[[self nameTextField] addTextFieldShouldChangeCharactersInRangeWithBlock:^BOOL(UITextField *textField, NSRange range, NSString *replacementString)
{
	self handleNameTextField:textField];
	return YES;
}];

[[self passwordTextField] addTextFieldShouldChangeCharactersInRangeWithBlock:^BOOL(UITextField *textField, NSRange range, NSString *replacementString)
{
	[self handlePasswordTextField:textField];
	return YES;
}];

This is specially useful to avoid forking your code. Yup, I hate ifs and switches.

Adding UITextField+DelegationBlocks to your project

Just add the two files inside your project (UITextField+DelegationBlocks.h and UITextField+DelegationBlocks.m).

CocoaPods: pod 'UITextField+DelegationBlocks', '~> 1.0'`

Finally import the category where you want to use it:

#import "UITextField+DelegationBlocks.h"

Usage

Currently I added this methods:

- (void)addTextFieldShouldChangeCharactersInRangeWithBlock:(TextFieldShouldReturnShouldChangeCharactersInRangeBlock)block;
- (void)addTextFieldShouldReturnWithBlock:(TextFieldShouldReturn)block;
- (void)addTextFieldShouldBeginEditingWithBlock:(TextFieldShouldReturn)block;
- (void)addTextFieldDidBeginEditingWithBlock:(TextFieldDidBeginEditing)block;
- (void)addTextFieldDidEndEditingWithBlock:(TextFieldDidEndEditing)block;

I will add more if I see a need to it (I am using this on my own projects), or anyone has the need for it. Still, if you want, you can always make a pull request.
