AutoKeyboardScrollView

[CI Status](https://travis-ci.org/Honghao Zhang/AutoKeyboardScrollView) Version License Platform

AutoKeyboardScrollView is a smart UIScrollView which can:

  • Scroll to proper position and make sure the active textField is visible when keyboard is showing
  • Customize top and bottom margin for textField
  • Dismiss keyboard when tap on scrollView
  • Dismiss keyboard on tap "Return"
  • New contentView which makes your life with Auto Layout easier

Preview

demo

Why?

Form views are very common when developing iOS projects. When keyboard is showing up, the big keyboard is covering great areas, which will hide the active textField.

It's kind of annoying to handle scrolling on UIScrollView and it's trivial to write keyboard notification and textField target action code again.

To keep your code DRY and make your life with iOS development easier.

Requirements

  • iOS 8.0+ / Mac OS X 10.9+
  • Xcode 7.0

Installation

CocoaPods

AutoKeyboardScrollView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "AutoKeyboardScrollView", '~> 1.4'

Manually

Just drag AutoKeyboardScrollView.swift (Located in ./Source, right click and Download Linked File) into your project and use it directly.

Usage

Just use AutoKeyboardScrollView as parent view of textFields, or views contain textFields. Add subViews on autoKeyboardScrollView.contentView (Be sure to add subViews on .contentView), then it just works!

(Note, only textField which is already on the view to be added can be handled, you can manually add textFields that need to be handled by calling handleTextField: or handleTextFields:)

To run the example project, clone the repo, and run pod install from the Example directory first.

How it works?

AutoKeyboardScrollView is a subClass of UIScrollView, some key features are list as following:

contentView

A new property: contentView is added, which is served same purpose as UITableViewCell. All subviews should be added on contentView, this is extremely helpful when dealing Auto Layout with ScrollView (refer: Apple Technical Note TN2154 - UIScrollView And Autolayout)

Note: To let AutoKeyboardScrollView determine its contentSize, the height and width of contentView must be fully specified.

Dismiss keyboard on Tap

AutoKeyboardScrollView will be attached with a Tap gesture and let you dismiss keyboard by tapping the empty space around textFields.

Dismiss keyboard on "Return"

AutoKeyboardScrollView will automatically detect textFields on newly added subViews, and add UIControlEditing actions for these textField, it will let you dismiss keyboard when tap "Return".

Work with Interface Builder

Create a wrapper view in IB, then add it as a subview on autoKeyboardScrollView.contentView.

See example project and select target InterfaceBuilderExample:

targets

Requirements

Works with Auto Layout, not tested on frame based code.

Support iOS 7 and above. Not tested on iOS 6, since Auto Layout came from iOS6, should be fine.
