Textfield scrolling relative to keyboard showing/hiding

Overview

The xcode project contains an example that implements the class "UITextfieldScrollViewController." When the keyboard appears, if focused textfield become hidden from the keyboard, it scrolls up to keyboard to be edited. It works for any iOS devices in portrait and landscape orientation.

##Installation

• Add UITextfieldScrollViewController.h and UITextfieldScrollViewController.m in your XCode project
• Subclass your custom viewcontroller with UITextfieldScrollViewController

• Since UITextfieldScrollViewController contains a scrollView outlet property, your custom view controller inherits that property, so connect scrollView as outlet in your custom view

• Since UITextfieldScrollViewController implements UITextfield delegate, connect your textfields as delegate in your custom view controller (File's Owner in this example)

That's all.

##Properties UITextfieldScrollViewController class contains two properties:

/* change this property to desiderate distance that textfield must have from keyboard when shown. Default value is set to DEFAULT_DISTACE_FROM_KEYBOARD
*/
@property (nonatomic, assign) CGFloat distanceFromKeyboard;

/* change this property if you want the textfield do not returns in own original position when keyboard is hiding. Default value is set to TRUE
*/
@property (nonatomic, assign) BOOL scrollToPreviousPosition;

You can change default values in viewDidLoad method of your custom view controller, as shown in the example below:

- (void)viewDidLoad
{
	[super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
	self.distanceFromKeyboard = 50.0;
	self.scrollToPreviousPosition = YES;
}
