iOS Firebase数据库URL

Question

I have been searching the web and gone through all tutorials I found about this subject, read the API reference but ultimately couldn't find any solution to my simple requirement.

In iOS / Swift, one has to install a "GoogleService-Info.plist" in the xCode project and then call FIRApp.configure() in the AppDelegate in order to load the configuration from the aforementioned plist file.

That all works perfectly, but what I would like now is being able to retrieve the parameters from this plist, to be more precise the database URL, so that I don't have to hardcode it anywhere (other than in that plist).

Of course I could use a dictionary to separately read the plist and retrieve the database url, but I would have expected to access the FIRApp object and retrieve it from there...

Did I miss something or is that option not given to retrieve the Firebase Parameters / Options directly from the FIRApp Object?

Answer 1

您可以使用FIRDatabase.database().reference()来获取通过FIRApp.configure()加载的数据库的引用。

Answer 2

I use a very simple extension ( Swift 4 ):

extension Database {
    var url: URL? {
        let refAsString = "\(FirebaseDatabase.Database.database().reference())"
        return URL(string: refAsString)
    }
}
