iOS Code Snippet Using OBJC to find the values of native constants

Erel said:

Apple documentation doesn't list the actual values of the various constants.
These values are needed when calling native methods with NativeObject.

You can use OBJC code to log these values:

B4X:

#if OBJC
-(void) test {
    NSLog(@"%@", NSForegroundColorAttributeName);
    NSLog(@"%@", NSUnderlineColorAttributeName);
    NSLog(@"%@", NSUnderlineStyleAttributeName);
    NSLog(@"%@", @(NSTextAlignmentRight)); //non-string values should be wrapped with @(...)
}
#End If

B4X:

Me.As(NativeObject).RunMethod("test", Null)
