I’m currently working with Applanga’s CTO to make their framework compatible with Xojo.

Applanga offers translation services for iOS and Android apps.

The Applanga framework relies on calls to Foundation. NSLocalizedStringWithDefaultValue to detect localisable strings in the app.

This is my call to NSLocalizedStringWithDefaultValue

Declare Function mainBundle Lib FoundationLib selector "mainBundle" (clsRef As ptr) As ptr

Declare Function NSLocalizedStringWithDefaultValue Lib FoundationLib (key As CFStringRef, _
tableName As CFStringRef, _
bundle As ptr, _
value As CFStringRef, _
comment As CFStringRef) As CFStringRef

  Return NSLocalizedStringWithDefaultValue(key, Nil, mainBundle(NSClassFromString("NSBundle")), value, "")

As soon as the above function is called, the app crashes :

Any ideas ?

I’m not sure that’s the right signature. I just looked this up in the apple docs:
It seems that the “function” you are trying to use doesn’t really exist without the C header (it’s a compiler define and not an actual function) so you should try the actual selector directly.

Thanks Jason.

Finally this seems to work:

[code]Declare Function mainBundle Lib FoundationLib selector “mainBundle” (clsRef As ptr) As ptr

Declare Function NSLocalizedString Lib FoundationLib selector “localizedStringForKey:value:table:” (bundle As ptr, _
key As CFStringRef, _
value As CFStringRef, _
table as CFStringRef) as CFStringRef

Return NSLocalizedString(mainBundle(NSClassFromString(“NSBundle”)), constName, value, nil)[/code]

Guess I’m confused why you need to declare into this at all ?
Dynamic constants already use this API so using dynamic constants should “just work”
