A link should open the app. I've got that to work. I just want to know how to pass a parameter. Let's say the url is "addappt://?code=abc". When a view controller pops up, a code field should have populated text - the letters after the equals to sign. I've got part of this to work. I use the following (in app delegate.m)
:
NSArray *elements = [url.query componentsSeparatedByString:@"="];
NSString *key = [[elements objectAtIndex:0] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
val = [[elements objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
(BTW: val is declared in appdelegate.h
I am also able to pass val
to the view controller. My only problem is populating the textfield, named 'code'
. How can you populate code as soon as the app is opened by the link?
Help Appreciated.
Here is a nice tutorial on Using Custom URL Scheme in iOS
As in the tutorial, you should parse the URL parameters and store them to use in the app in this method:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
// Do something with the url here
}
