iOS – Audio and Video

In this article we are reading about “iOS – Audio and Video”.
Audio and video is quite common in the latest devices. It is supported in iOS with the help of AVFoundation.framework and MediaPlayer.frameworkrespectively.

Steps Involved

Step 1 − Create a simple View based application.
Step 2 − Select your project file, select targets, and then we should add AVFoundation.framework and MediaPlayer.framework.
Step 3 − Add two buttons in ViewController.xib and create an action for playing audio and video respectively.
Step 4 − Update ViewController.h as follows −

#import <UIKit/UIKit.h>

#import <MediaPlayer/MediaPlayer.h>

@interface ViewController : UIViewController {
AVAudioPlayer *audioPlayer;
MPMoviePlayerViewController *moviePlayer;
}
-(IBAction)playAudio:(id)sender;
-(IBAction)playVideo:(id)sender;
@end
Step 5 − Update ViewController.m as follows −

#import "ViewController.h"

@interface ViewController ()
@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];
}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

-(IBAction)playAudio:(id)sender {
NSString *path = [[NSBundle mainBundle]
pathForResource:@"audioTest" ofType:@"mp3"];
audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:
[NSURL fileURLWithPath:path] error:NULL];
[audioPlayer play];
}

-(IBAction)playVideo:(id)sender {
NSString *path = [[NSBundle mainBundle]pathForResource:
@"videoTest" ofType:@"mov"];
moviePlayer = [[MPMoviePlayerViewController
alloc]initWithContentURL:[NSURL fileURLWithPath:path]];
[self presentModalViewController:moviePlayer animated:NO];
}
@end

Note

We need to add audio and video files for ensuring that we get the expected output.

Output

When we run the application, we’ll get the following output −
iOS - Audio and Video
When we click on play video, we will get an output as shown below −
iOS - Audio and Video
When we click play audio, you will hear the audio.
So in this article we have read about “iOS – Audio and Video”.

Java Number Class

In this article we are reading about  “ Java Number Class ” . Java Number class is an  abstract  class which is placed in  java.lang  package. It has  four  abstract methods and two  concrete methods. The abstract class Number is the superclass of classes BigDecimal, BigInteger, Byte, Double, Float, Integer, Long, and Short. This class contains a single consructor  number() . In Java language, we mostly work with a  primitive data type , but Java also provides a  wrapper class  under the abstract class numbers in java.lang package, there are six subclasses under the class ‘numbers’. The primitive data types are ‘wrapped’ under these Java classes for their corresponding objects. This wrapping is usually done by the compiler. When an object is converted into primitive type than it is called Autoboxing, and then again transferred to an object it is called Unboxing. The following figure shows the class hier...

Java Character Class

In this article we are reading about  “ Java Character Class ” . The Character class simply a wrapper class for the primitive type char. It wraps the char primitive value to an object. An object of type Character contains a single field whose type is char .  So what would be the benefit if wraps around the primitive data type to an object? Well basically we would be able to access all the methods that is readily available on the Character class which is very useful. In addition, this class provides several methods for determining a character’s category (lowercase letter, digit, etc.) and for converting characters from uppercase to lowercase and vice versa. We will go over each and every method available to Byte class thoroughly. Character information is based on the Unicode Standard, version 6.2.0. The methods and data of class Character are defined by the information in the UnicodeData file that is part of the Unicode Character Datab...

In this article we are reading about  “What are Web Resources in Microsoft Dynamics 365 ?” . Web Resources in Dynamics 365  are virtual files stored in the Dynamics 365 Database and typically used by developer and designer to extend web application. In Dynamics 365(online), we use Web resources to upload upload files to Dynamics 365 database and then reference them by name. In Dynamics 365, Web resources are limited to specific types of filters. The following types of files can be used to create Web Resources in Dynamics 365. File Type File name extension Webpage (HTML) .htm, .html Style Sheet(CSS) .css Script(Jscript, JavaScript) .js Data (XML) .xml Image (PNG, JPG, GIF) .png, .jpg,  .gif.
