IOS app calls built-in applications (SMS, email, browser, MAP, appstore, and call number)

In a program, you can call an application that comes with the system. For example, when I enter the program, I want to directly call Safar to open a webpage. Below is a simple usage:

- (BOOL) application: (UIApplication *) application didFinishLaunchingWithOptions: (launchOptions NSDictionary *)
{
Self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
Self.viewcontroller = [[[viewController alloc] initWithNibName: @viewcontroller "bundle:nil] autorelease];
The self. The window. The rootViewController = self. ViewController;
[the self. The window makeKeyAndVisible];

// call safar to open the page
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: @ "http://www.cnblogs.com/foxmin"]].
//// call app store (ellipsis followed by product id and other parameters)
/ / [[UIApplication sharedApplication] openURL: [NSURL URLWithString: @ "itms://itunes.apple.com/app/..."]].
/ / [[UIApplication sharedApplication] openURL: [NSURL URLWithString: @ "itms-apps://itunes.apple.com/app/"]].
//// call the telephone
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://XXXXX"]];
/ / / / call the SMS
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@" SMS ://XXXXX"]];
/ / / / invoke the Remote
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"remote://XXX"]];

Return YES;
}

For more iPhone application calls and third-party application calls, you can view the iPhone URL scheme. The following lists the parts:

Apple iPhone applicationssafari

Any URL starting with http: // which does not point to maps.google.com or www.youtube.com is sent to Safari:

NSString *stringURL = @"http://wiki.akosma.com/";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

Apparently feed: // opens http://reader.mac.com in
Safari.

Maps

URLs starting with http://maps.google.com open up the "maps" application automatically:

NSString *title = @"title";
float latitude = 35.4634;
float longitude = 9.43425;
int zoom = 13;
NSString *stringURL = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@@%1.6f,%1.6f&z=%d", title, latitude, longitude, zoom];
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

It seems that maps: // also opens up the Maps application.

Phone

The phone links start with "Tel:" but must not contain spaces or brackets (it can contain dashes and "+" signs, though ):

NSMutableString *phone = [[@"+ 12 34 567 89 01" mutableCopy] autorelease];
[phone replaceOccurrencesOfString:@" " 
                       withString:@"" 
                          options:NSLiteralSearch 
                            range:NSMakeRange(0, [phone length])];
[phone replaceOccurrencesOfString:@"(" 
                       withString:@"" 
                          options:NSLiteralSearch 
                            range:NSMakeRange(0, [phone length])];
[phone replaceOccurrencesOfString:@")" 
                       withString:@"" 
                          options:NSLiteralSearch 
                            range:NSMakeRange(0, [phone length])];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", phone]];
[[UIApplication sharedApplication] openURL:url];

SMS

To open the SMS application, just use the SMS: Protocol in your url:

NSString *stringURL = @"sms:";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

You can specify a phone number, but apparently not a default text for your message:

NSString *stringURL = @"sms:+12345678901";NSURL *url = [NSURL URLWithString:stringURL];[[UIApplication sharedApplication] openURL:url];

The same restrictions apply as for phone URLs, regarding spaces, brackets and dashes.

Mail

These URLs launch mail and open the compose message controller:

NSString *stringURL = @"sms:+12345678901";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

You can also provide more information, for a customized subject and body texts:

NSString *stringURL = @"mailto:test@example.com";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

You might also omit some information:

NSString *subject = @"Message subject";
NSString *body = @"Message body";
NSString *address = @"test1@akosma.com";
NSString *cc = @"test2@akosma.com";
NSString *path = [NSString stringWithFormat:@"mailto:%@?cc=%@&subject=%@&body=%@", address, cc, subject, body];
NSURL *url = [NSURL URLWithString:[path stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[[UIApplication sharedApplication] openURL:url];

For more complex body texts, you might want to use the cfurlcreatestringbyaddingpercentescapes () function, as fig in this page.

YouTube

URLs starting with the http://www.youtube.com open up the "YouTube" application automatically:

NSString *stringURL = @"http://www.youtube.com/watch?v=WZH30T99MaM";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

It also works with this URL (which normally brings the Flash video player used by YouTube ):

NSString *stringURL = @"http://www.youtube.com/v/WZH30T99MaM";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

ITunes

To open up iTunes, use this URL:

NSString *stringURL = @"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewAlbum?i=156093464&id=156093462&s=143441";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

App Store

Very similar to the iTunes urls:

NSString *stringURL = @"http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=294409923&mt=8";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

Ibooks

(Source: http://akos.ma/aqdr)

NSString *stringURL = @"itms-books:";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

NSString *stringURL = @"itms-bookss:";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

Third party applications

NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

Duo

Launch the application and pre-populate the update field with your desired tweet/Facebook update. optional: Provide duo with the custom URL and return path to your app to provide the user with a button to return to your app.

NSString *appID = @"Your Apps Name";
NSString *updateInfo = @"The Tweet/Status Update";
NSString *returnScheme = @"Your Apps Return URL Scheme";
NSString *returnPath = @"Your/Apps/Return/Path";
NSString *baseURL = @"duoxx://updateFaceTwit?";
	
NSString *encodedUpdateInfo = [updateInfo stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSString *urlString = [NSString stringWithFormat:@"%@BLappID=%@;BLupdateInfo=%@;BLreturnScheme=%@;BLreturnPath=%@", 
						   baseURL, appID, encodedUpdateInfo, returnScheme, returnPath];

NSURL *url = [NSURL URLWithString:urlString];
[[UIApplication sharedApplication] openURL:url];

 

The cartographer

Launch app and add a placemark at given coordinate:

NSString *title = @"Placemark title (optional)";

NSString *summary = @"Placemark description (optional)";

CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(123.0, 12.0);

title = [(id)CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)title, NULL, (CFStringRef)@";/?:@&=+$,", kCFStringEncodingUTF8) autorelease];

summary = [(id)CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)summary, NULL, (CFStringRef)@";/?:@&=+$,", kCFStringEncodingUTF8) autorelease];

NSString *cartographerURL = [NSString stringWithFormat:@"cartographer://placemark?coordinate=%lf,%lf&title=%@&summary=%@",

        coordinate.latitude, coordinate.longitude, title, summary];

NSURL *url = [NSURL URLWithString:cartographerURL];

[[UIApplication sharedApplication] openURL:url];
