Text to Speech in iOS7

iOS7 makes Text to Speech really easy and that also in multiple languages.
iOS7 has added two new classes for Text to Speech functionality:
1. AVSpeechSynthesizer
2. AVSpeechUtterance

First Link AVFoundation and AudioToolbox Framework from Application Target -> Build Phases -> Link Binary With Libraries.

Import both frameworks in Header file (.h file)
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>

add delegate <AVSpeechSynthesizerDelegate>.

In implementation file (.m file)
    AVSpeechSynthesizer *speechSynthesizer = [[AVSpeechSynthesizer alloc] init];
    AVSpeechUtterance *speechUtterance = [AVSpeechUtterance speechUtteranceWithString:@"Welcome to iOS App."];
    speechUtterance.rate = AVSpeechUtteranceMaximumSpeechRate / 4.0f;
    speechUtterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-US"]; // language
    [speechSynthesizer speakUtterance: speechUtterance];

 By adding the above code you can add text to speech functionality to your iOS7 app.

Unique Identifier UUID - iOS

UDID is a hash value composed from various hardware identifiers such as the device serial number. It is unique for each device.  The UDID is independent of the device name, SIM card. It is really easy to get it from the device programmatically: NSString *uuid =  [[UIDevice currentDevice] uniqueIdentifier]; But UDID is no longer available onwards iOS 6 due to security / privacy reasons. UDID is deprecated by Apple; developers can not make use of it in any iOS application. So what now?  How can we identify the device? I found many solutions on searching over internet like  identifierForVendor or  advertisingIdentifier or generate our own UUID (store & persist it on your own). Many examples show how to generate UUID and store it in NSUserDefault: -( NSString *)generateUUID {     NSString *CFUUID = nil ;     if ([[ NSUserDefaults standardUserDefaults ] valueForKey : @"UUID" ] == nil ) {   ...

Add object of UIViewController (viewController here) as rootviewcontroller of UINavigationController. 4. In ViewController.xib nib file take a UITableView. 5. Set delegate and datasource of UITableView to File's Owner. 6. Create an IBOutlet to UITableView (tableViewForScreen here) in ViewControler.h header file. 7.

In ViewController.m file in viewDidLoad method set edit and add buttons as leftBarButtonItem and rightBarButtonItem respectively. 9. Initialize arrayForTableContent array and add objects to it. ...
