iOS程序中调用系统自带应用(短信，邮件，浏览器，地图，appstore，拨打电话)
在程序中调用系统自带的应用，比如我进入程序的时候，希望直接调用safar来打开一个网页，下面是一个简单的使用：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
//调用safar打开网页 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.cnblogs.com/foxmin"]];
////调用app store (省略号后面加的是产品的id等一些参数)
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms://itunes.apple.com/app/……"]];
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-apps://itunes.apple.com/app/ "]];
////调用电话
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://XXXXX"]];
////调用SMS
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://XXXXX"]];
////调用Remote
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"remote://XXX"]];
return YES;
}
查看更多iPhone应用程序的调用和第三方应用程序的调用，可以在iPhone的URL方案查看。下面列举部分：
Apple iPhone Applications
Safari
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];
Apparentlyfeed:// openshttp://reader.mac.comin Safari.
Maps
URLs starting withhttp://maps.google.comopen 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 seemsthat 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.
These URLs launch Mail and open the compose message controller:
NSString *stringURL = @"mailto:test@example.com"; NSURL *url = [NSURL URLWithString:stringURL]; [[UIApplication sharedApplication] openURL:url];
You can also provide more information, for a customized subject and body texts:
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];
You might also omit some information:
NSString *subject = @"Message subject"; NSString *path = [NSString stringWithFormat:@"mailto:?subject=%@", subject]; 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 explained above in this page.
YouTube
URLs starting withhttp://www.youtube.comopen 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];

summary = [(id)CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)summary, NULL, (CFStringRef)@";/?:@&=+$,", kCFStringEncodingUTF8) autorelease];
NSString *cartographerURL = [NSString stringWithFormat:@"cartographer://placemark?coordinate=%lf,%lf&title=%@&summary=%@",

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