I want to register my application to handle a specific domain, for example:
http://mycompany.com would open my application if it is installed on the device. Is this possible? I know that I can register a url scheme, like mycompany://, but I want to be able to handle a standard url.
You can’t do this unfortunately, iOS only lets 3rd party apps register to handle custom URL schemes, not domains.
The mechanism whereby different apps intercept youtube, maps, iTunes URLs, etc. is private to Apple’s own applications.
