问题 I have a Cocoa application with an AppleScript dictionary described in a .sdef XML file. All of the AppleScript classes, commands, etc. defined in the sdef are working property. Except for my "submit form" command. The "submit form" command is my only command attempting to pass a parameter that is an arbitrary hashtable of information from AppleScript to Cocoa. I assume this should be done by passing an AppleScript record which will be automatically converted to an NSDictionary on the Cocoa

问题 I'm trying to debug an iPhone app I'm working on, and the idea of adding fifty NSLog statements to the various source files gives me the willies. What I'd like to do is write a pair of statements, say NSString *methodName = [self methodName]; NSLog(@"%@", methodName); that I can just paste into each method I need to. Is there a way to do this?
