iPhone & iPad apps with special url shortcuts

A feature of the iPhone SDK allows you to bind your application to a custom url scheme. This allows others to trigger the opening of your app and opens the possibilities of passing data between apps.

Here’s a quick tutorial on how to update your Info.plist to register your own url.

List of iPhone apps with custom url shortcuts along with instructions on how to use them.

Safari

  • sms:123456789 – There is no // in the SMS scheme.
  • Note: Currently no method to specify a body for the message.

Send an Email

Like YouTube and Google Maps, certain http urls get hijacked by the build in Apple apps. This will open the Appstore app.

UniDict Engine & SpellChecker

by Enfour

Enfour has a number of apps that support round-trip URLs -add the sender app’s URL to the ‘Back’ button.

“UniDict Engine” (used for dictionaries like “American Heritage” & “Oxford Deluxe“) allows lookups from other applications as well as links between dictionaries.

“SpellChecker” also has round trip URLs. This lets apps send text to be checked with the results sent back to the app that made the call.

Pocket Universe

by John Kennedy

Pocket Universe supports the following options (more to come), which makes it possible to link to planets or points in the sky from a web page and then ’see’ them in the app’s planetarium mode. Motion tracking mode must be off for these to function as expected.

PageControl Without Application Delegates

1---> Create A Scroll View With Array Of Views
Each View's Dimension is 320x420
2---> in viewDidLoad ->
Arr_Element=[[NSMutableArray alloc]initWithObjects:@"First",@"Second",@"Third",@"Fourth",nil];
Arr_Count=[Arr_Element count]; //Arr_Count-> int
[Scrl setContentSize:CGSizeMake(Arr_Count*320,Scrl.bounds.size.height)];
pageControl.numberOfPages = Arr_Count;
pageControl.currentPage = 0;
for(int i=0;i {

UIView *Page_View=[[UIView alloc]initWithFrame:CGRectMake(i*320, 0, 320,420)];
UILabel *Lbl=[[UILabel alloc]initWithFrame:CGRectMake(10,10,300, 50)];
Lbl.text=[NSString stringWithFormat:@"%@",[Arr_Element objectAtIndex:i]];
Page_View.backgroundColor=[UIColor blueColor];
[Page_View addSubview:Lbl];
[Scrl addSubview:Page_View];
[Page_View release];
[Lbl release];
}

3---> - (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGFloat pageWidth = Scrl.frame.size.width;
int page = floor((Scrl.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
pageControl.currentPage = page;
pageControl.frame=CGRectMake(Scrl.contentOffset.x,415,320, 36);
}

4---> - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
pageControl.currentPage = (int)Scrl.contentOffset.x/320;
pageControl.frame=CGRectMake((int)Scrl.contentOffset.x,415,320, 36);
}

5---> -(void)Change:(id)sender
{
[Scrl scrollRectToVisible:CGRectMake(320*pageControl.currentPage, 0,320, 420) animated:YES];
}
6---> And Refer Change Method With PageControl-> Value Change
