How to Override Silent switch while playing sounds in an iPhone/iPad app using AVPlayer

As you guys know there are 2 ways to play sound files from the within app like game sounds, warning/caution sounds or alarm sounds.

One is by using Audio Services in AudioToolBox frame work.
And the other is by using AVPlayer in AVFoundation frame work.

You can follow How to play sounds in an iPhone/iPad app tutorial to learn how to play sounds in an iOS app.

The trick to override the switch is possible only by using AVPlayer, and here is how we can accomplish that.
Just use the below line, must be used in viewDidLoad or some where before using AVPlayer classes.

Beginner's Choice

My dear developers,

Am Vishwanath, started my career directly from learning Objective-C building iOS applications. Before this i was just aware of C and C++ languages only. Now i have over 2.8 years on Obj-C and 2.4 years on iOS SDK. Have built apps on iPhone, iPod and iPad applications.
So far in my journey i have learned some skills like-

• Hands on features/services like MapKit, Location based services, Web services based, XML, JSON, PDF, Paypal, in-app Purchases, Core data, iCloud.
• Hands on e-commerce applications, Social networking applications, Event based applications.

In my journey i have built lots of sample applications to learn different concepts, different frameworks. Just for learning my self. Have come across lots of hurdles- found solutions, tricks and tips to complete the tasks in a easier way.Using these experiences which i gained so far we can build simple applications just like that in no time, and can decide which will be best out of many ways to accomplish the tasks/hurdles building any applications.

  
Now i can say that am a Beginner's Level-2 in iOS development. So want to help my co-developers, who want to start a career in iOS development or Beginner's Level-1. So that you can cross these hurdles in no time and develop great applications in less time.

To start this i will be posting Tutorials, Tips, Tricks, to complete Tasks and many more in this blog. So subscribe to this blog & be in touch to save your time in development. These tips will be really helpful in real time while building apps in many ways, so just have look on it.

How to make use of Digital Color Meter application in MAC

We have an application in our MAC called "DigitalColor Meter". We can use this application into our application to get the color code for RGB. Steps: 1)   Open Digital Color Meter application in MAC, can use spot light for easy search. 2)   Keep the required mode to "RGB as Percentage" 3)   Using the mouse pointer go to the required color on the screen. 4)   Note down the RGB values in percentage. 5)   In our code you can use the method  [UIColor colorWithRed:0.663 green:0.855 blue:0.341 alpha:1] Convert percentage values into fractions. like 53.5% will become 0.535. Use the respective RGB values in the code, and alpha value must be 1. Run the application, you will get the exact color required.

For HTML users In the "DigitalColor Meter" application set the mode to "RGB As actual value, 8-bit", so that you can get the RGB value as decimal number from 0-255. Note this RGB numbers.    Use RGB-HEX to get the hexadecimal number of the required color by inserting these RGB values. for example: R - 85   G - 20   B - 30 required color in hexadecimal is : #55141E You can use this hexadecimal value, to get the required color in html code.

Happy Coding.
