UIPopoverController Tutorial For iPad with iOS8 Swift: iOS Programming

UIPopoverController Tutorial



UIPopoverController is similar to Action Sheet. it is also another cool and important tool, especially for the iPad. PopoverController is a nice way to present information to the user.A popover controller is nothing but a container which is used to display content on top of another content. UIPopoverController’s content is layered on top of your existing content in a special type of window.
In our Previous Tutorial, we have already completed UIActionSheet so if you have not then read out Action Sheet Tutorial.

Project Setup:

This Tutorial is built in Xcode 8.2.1 so if you have not update your Xcode, First Update Xcode. Now Open Xcode and create a new Single View Application. In product name, use PopoverTutorialDemo and then fill out the Organisation Name and Organisation Identifier with your customary values. Select Swift as Language and make sure you have select iPad style for Devices.


Make UIDesign:

Go to the Storyboard, drag a Button from the Object Library to the View Controller inside the Storyboard. Double-click the Button and give it a title of “Show PopOver” or whatever you want.

Make IBOutLayoutConnection for UIButton:

Open the Assistant Editor. Ctrl + drag from the Button to the ViewController class and create the following Action and Click on Connect.



add UIPopoverController variable in ViewController class. This variable will be used in the ShowPopOverMthod.
var popOverData = UIPopoverController()
Now, we will create a new viewController. Add a new File -> iOS -> Cocoa Touch -> Swift class and make it a subclass of UITableViewController. Select the “With XIB for user interface” checkbox and name the class UserDataViewController.



Update Xib User Interface:
Go to UserDatViewController.xib and select UITableViewCell from object Library and dragon to xib. Now select Cell and give the cell identifier name with “reuseIdentifier”.

Implement UserDataViewController Class:

Go to UserDataViewController.swift. Inside This Class update the class with following code. This code is simple because we are just trying to register the TableViewCell and update DataSource methods of TableView Protocol.
return 1 under the numberOfSections method.
return 10 under the tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) method.
Uncomment tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell method.

import UIKit
class UserDataViewController:  UITableViewController{ 
//...




 
 
 


// in viewDidLoad method.
self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "reuseIdentifier")

//in tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell 

 var cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath) as? UITableViewCell
 cell?.textLabel?.text = "This is User \(indexPath.row)'s cell"
 
}
Now come back to ViewController class and add this code inside ShowPopOverMethod.
import UIKit
class ViewController:  UIViewController{ 
//...
let PopoverView = UserDataViewController(nibName: "UserDataViewController", bundle: nil)
self.popOverData = UIPopoverController(contentViewController: PopoverView)
self.popOverData.present(from: sender.frame, in: self.view, permittedArrowDirections: .down, animated: true) 
}

Now Build and run the App and click on “Show PopOver” button. Great New PopOver View will be Appear.

React Native - Text Input

In this chapter, we will show you how to work with  TextInput  elements in React Native. The Home component will import and render inputs. App.js import React from 'react' ; import Inputs from './inputs.js' const App = () => { return ( < Inputs /> ) } export default App Inputs We will define the initial state. After defining the initial state, we will create the  handleEmail  and the  handlePassword  functions. These functions are used for updating state. The  login()  function will just alert the current value of the state. We will also add some other properties to text inputs to disable auto capitalisation, remove the bottom border on Android devices and set a placeholder. inputs.js import React , { Component } from 'react' import { View , Text , TouchableOpacity , TextInput , StyleSheet } from 'react-native' class Inputs extends Component { state = { ...

An introduction to Size Classes for Xcode 8

Introduction to Size Classes for Xcode In iOS 8, Apple introduced  size classes , a way to describe any device in any orientation. Size classes rely heavily on auto layout. Until iOS 8, you could escape auto layout. IN iOS8, Apple changed several UIKit classes to depend on size classes. Modal views, popovers, split views, and image assets directly use size classes to determine how to display an image. Identical code to present a popover on an iPad  causes a iPhone to present a modal view. Different Size Classes There are two sizes for size classes:  compact , and  regular . Sometime you’ll hear about any.  Any  is the generic size that works with anything. The default Xcode layout, is  width:any height:any . This layout is for all cases. The Horizontal and vertical dimensions are called  traits , and can be accessed in code from an instance of  UITraitCollection . The  compact  size descr...

No matter what iOS user is using, you can get the UDID of the current iOS device by following code. - ( NSString *)UDID { NSString *uuidString = nil ; // get os version NSUInteger currentOSVersion = [[[[[UIDevice currentDevice ] systemVersion ] componentsSeparatedByString: @" . " ] objectAtIndex: 0 ] integerValue ]; if (currentOSVersion <= 5 ) { if ([[ NSUserDefaults standardUserDefaults ] valueForKey: @" udid " ]) { uuidString = [[ NSUserDefaults standardDefaults ] valueForKey: @" udid " ]; } else { CFUUIDRef uuidRef = CFUUIDCreate ( kCFAllocatorDefault ); uuidString = ( NSString *) CFBridgingRelease ( CFUUIDCreateString ( NULL ,uuidRef)); CFRelease (uuidRef); [[ NSUserDefaults standardUserDefaults ] setObject: uuidString ForKey: @" udid " ]; [[ NSUserDefaults standardUserDefaults ] synchro...
