A method is depreciated in framework but cannot apply suggested change

I'm using a framework that is written in-house and when I try to reduce the amount of warnings I have there is one that comes up constantly, which is 'Implementing depreciated method'. the method in question is openURL

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation

When I go to the Framework code I can see where it is depreciated and a suggested change

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(nullable NSString *)sourceApplication annotation:(id)annotation NS_DEPRECATED_IOS(4_2, 9_0, "Please use application:openURL:options:") __TVOS_PROHIBITED;

The suggestion is to use openURL:options. Looking at the documentation for openURL it says I should use like the following

UIApplication *application = [UIApplication sharedApplication];
[application openURL:URL options:@{} completionHandler:nil];

However, this doesn't work, I cannot separate the parameter openURL from the method as it states above when my method looks like this

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{
..
}

How do I implement the new suggested change into my existing method call as above?

Solution

  • The method that you need to implement is application:openURL:options: instead of deprecated one application:openURL:sourceApplication:annotation:. So replace your method with below one

    - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options {
    //Your code ..
}

    Note :- The instance method openURL:options:completionHandler: that you are trying to use is used to open the resource at the specified URL asynchronously.
