Start your app with a custom URL Scheme

Http://blog.csdn.net/ba_jie/article/details/6884818

The iPhone SDK can bind your app to a custom URL scheme. This URL scheme can be used to start your app from a browser or another app.

It is up to you to decide how to respond to the URL Scheme Application sent to you from another app: you can wake up your app or send some information to you.

It is very easy to register a URL scheme for your app. It is OK to define two key values in the info. plist file. As shown in:

1. Add a key value called URL types.
2. Add a URL identifier to item 1 in the format of Reverse Domain Name: COM. mycompany. MyApp.
3. Add a URL scheme and define a value for it, any string. For example, MyApp.

After the definition ends, you can use the following mode to send a URL:

MyApp ://
MyApp: // some/path/here
MyApp ://? Foo = 1 & amp; bar = 2
MyApp: // some/path/here? Foo = 1 & amp; bar = 2

Then, your app's uiapplicationdelegate will receive a message. If you want to process the URL by yourself, you can reload the following method:

[Plain] View
Plaincopy

2. -(Bool) Application :( uiapplication *) Application handleopenurl :( nsurl *) URL
4. {
6. // Do something with the URL here
8. }

For example, save the uploaded URL locally:

[Plain] View
Plaincopy

2. -(Bool) Application :( uiapplication *) Application handleopenurl :( nsurl *) URL
4. {
6. If (! URL)
8. {
10. Return no;
12. }
16. Nsstring * urlstring = [url absolutestring];
18. [[Nsuserdefaults standarduserdefaults] setobject: urlstring forkey: @ "url"];
20. [[Nsuserdefaults standarduserdefaults] synchronize];
22. Return yes;
24. }
