Frustrating problem with NSTextView

I want to print out the Text contents of a NSTextView using the NSLog functio开发者_JAVA技巧n in Objective-C. The code I have so far is:

NSString *s=[updateSource textStorage];

NSLog(s);

All I get is the error:

[NSConcreteTextStorage getCharacters:range:]: selector not recognized [self = 0x43f4b0]

Use [updateSource string] instead. [updateSource textStorage] is not an NSString, but rather an NSTextStorage.

It's not the cause of your problem, but you should be using NSLog(@"%@",s); to log your string. The first argument of NSLog should always be a format string, and not the value you're trying to log.

(if you don't, your app will likely crash if the value contains percent characters)
