Playing audio in iPhone

We can play audio files in the same way we played the video. The only difference is the file extensions. We just need to change extension of the file. That's it.

Playing video in iPhone

#import "PlayVideoViewController.h"
#import "MediaPlayer/MediaPlayer.h"

@implementation PlayVideoViewController



- (void)viewDidLoad
{

NSString *url = [[NSBundle mainBundle]
pathForResource:@"Miracle"
ofType:@"mp4"];

MPMoviePlayerController *player =
[[MPMoviePlayerController alloc]
initWithContentURL:[NSURL fileURLWithPath:url]];

[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];

//---play movie---
[player play];

// Changing the orientation
// [player setOrientation:UIDeviceOrientationPortrait animated:NO];
[super viewDidLoad];
}



- (void) movieFinishedCallback:(NSNotification*) aNotification {
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player autorelease];
}
@end

Sending email through iPhone

-(IBAction)sendButtonPressed
{
[self sendEmailTo:txtTo.text withSubject:txtSubject.text withBody:txtBody.text];
}

-(void)sendEmailTo:(NSString *)to withSubject:(NSString *)subject withBody:(NSString *)body
{
NSString *mailString = [NSString stringWithFormat:@"mailto:?to=%@&subject=%@&body=%@",
[to stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
[subject stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
[body stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailString]];

UIAlertView *myAlert=[[UIAlertView alloc] initWithTitle:@"Success" message:@"Email sent" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[myAlert show];
[myAlert release];
}

Welcome Note

It's just been created. I'll post my essential codes later on.
