 1 | About
 2 | =====
 3 | `XCDFormInputAccessoryView` is a view to be used above the keyboard with *previous*, *next* and *done* buttons for navigating text fields.
 4 | 
 5 | ![screenshot](https://github.com/0xced/XCDFormInputAccessoryView/raw/master/Screenshots/XCDFormInputAccessoryView.png)
 6 | 
 7 | `XCDFormInputAccessoryView` uses ARC (Automatic Reference Counting) and must be built with Xcode 4.5 or greater. It has been tested on iOS 4, 5 and 6.
 8 | 
 9 | Usage
10 | =====
11 | In your `UIViewController` subclass, redeclare the `inputAccessoryView` property and create a new instance of `XCDFormInputAccessoryView`, for example in your `viewDidLoad` method:
12 | 
13 | 	#import "XCDFormInputAccessoryView.h"
14 | 	
15 | 	@interface MyViewController ()
16 | 	@property (nonatomic, strong) XCDFormInputAccessoryView *inputAccessoryView;
17 | 	@end
18 | 	
19 | 	@implementation MyViewController
20 | 	- (void) viewDidLoad
21 | 	{
22 | 		[super viewDidLoad];
23 | 		self.inputAccessoryView = [XCDFormInputAccessoryView new];
24 | 	}
25 | 	@end
26 | 
27 | If you want to have total control over what the **Previous** and **Next** buttons do, you should initialize `XCDFormInputAccessoryView` with the `initWithResponders:` method instead and pass an array of `UIResponder` instances. If you do not supply an array of responders, then `XCDFormInputAccessoryView` uses the following heuristic to find which text input views will be used:
28 | 
29 | 1. Find all text fields and editable text views in the key window
30 | 2. Sort them using their frame origin vertical position
