Video for iPhone/iPad using MPMoviePlayerController

sergio — Sun, 11 Mar 2012 17:26:18 +0000

First of all, we need to add the framework MediaPlayer to the project (MediaPlayer.framework) and then include the header file:

#import

Suppose we saved the MP4 file on disk. We have to provide the path in our code:

NSString *path = [[NSBundle mainBundle] pathForResource:@"nombre-video-sin-ext" ofType:@"mp4"];
NSURL *url = [NSURL fileURLWithPath:path];

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

Now we have to set the video size and position. It is worth noting that MPMoviePlayerController inherits from UIViewController so we set the player.view properties.

player.view.frame = CGRectMake(50, 50, 698, 500);
[self.view addSubview:player.view];
[player prepareToPlay];

Finally, if we want to manage the video we will use:

[player play];
[player pause];
[player stop];

If we want to perform an action when the video ends, we can use notifications. For example:

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

y pass the object player as a parameter to the function movieFinishedCallback:

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

We are ready to watch videos on iPad or iPhone.

Double tap using UIGestureRecognizer for UIWebView

sergio — Sat, 26 Nov 2011 15:32:02 +0000

Today we are going to show how to catch the Tap events from a UIWebView and same for double Tap.

Using an UIWebView wView, we create new object UITapGestureRecognizer tgr

UIWebView * wView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, WIDTH, HEIGHT)];
UITapGestureRecognizer *tgr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(DobleTap: )];

Now we set the number of touches/taps

tgr.numberOfTapsRequired=2;

Add tgr to wView

tgr.delegate = self; // Opcional
[wView addGestureRecognizer: tgr];

and at the end we create the DobleTap function referred before

-(void) DobleTap: (UIGestureRecognizer *) sender {
// Sentencias
}

Hope help!

How to get the country name on iPhone/iPad

sergio — Sun, 09 Oct 2011 08:59:47 +0000

Apple uses the ISO standard ISO-3166 for representing the country names. ISO 3166-1 defines codes for the names of countries, dependent territories, and special areas of geographical interest.

For example:

ISO english country names	Alpha-2	Alpha-3	Numeric code	ISO 3166-2
United Kingdom	`GB`	`GBR`	`826`	ISO 3166-2:GB
United States	`US`	`USA`	`840`	ISO 3166-2:US

To get the country name on a iPhone we define a NSLocale variable and we use NSLocaleCountryCode:

NSLocale *locale = [NSLocale currentLocale];
NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];

If we want to get the english country name we can do the next:

NSString *countryName = [locale displayNameForKey: NSLocaleCountryCode value: countryCode]];

Note: More information in Apple’s documentation.

How to write text in an iPhone CGContextShowTextAtPoint

sergio — Sat, 01 Oct 2011 16:32:44 +0000

I’m going to show how to write a text on an iPhone using the CGContextShowTextAtPoint. First problem is that by default the text will appear inverted, so we need to tranform it. A possible solution could be:

void drawText (CGContextRef myContext, char *title, int x, int y, int w, int h)
{
CGContextSelectFont (myContext, “Arial”, h/10, kCGEncodingMacRoman);
CGContextSetRGBFillColor (myContext, 0, 0, 0, 0.99);
CGContextSetTextMatrix(myContext, CGAffineTransformMake(1.0,0.0, 0.0, -1.0, 0.0, 0.0));
CGContextShowTextAtPoint (myContext, x, y, title, strlen(title));
}

The key is on the

CGAffineTransformMake(1.0,0.0, 0.0, -1.0, 0.0, 0.0)

transformation.
