Hi
I am pretty new to cocoa and try to refill a NSTextView interface object with new text, but it just does not want to work...
I dropped the "Text View" (NSScrollView) item out of the "Cocoa"->"Views & Cells" folder onto the application.
I declared
IBOutlet NSTextView* registers;
in my class in XCode, loaded the class into the application builder and connected an object of my class with the NSTextView part of the item I dropped onto the application (from object to item).
This seems right to me (at least it does work :D), but whatever I want to do with "registers" does not work...
As I mentioned before, my aim is to replace the whole text with a new (C-)String/char-construct (char*).
I tried
[[registers textStorage] replaceCharactersInRange:NSMakeRange([[registers textStorage] length], 0) withString:@"Hi. Nur ein Test "];
as a little test. Does not work.
A little bit shorter
[[registers textStorage] replaceCharactersInRange:NSMakeRange(0, 0) withString:@"Hi. Nur ein Test "];
also no effect...
I played around with objects of the type NSAttributedString, creating, trying to use the inherited methods of NSTextStorage from NSAttributedString to insert the NSAttributedString into the TextStorage - does not work.
At the moment, I tried something very simple:
NSTextStorage* store = [registers textStorage];
I inspected it in the debugger and it says "0x0" for the value... well seems wrong to me!
Next line:
NSString* blubb2 = [store string];
This should then return the current content of the textbox as far as I know, actually the variable contains value:"0x0";Summary:"nil"... well, seems incorrect to me too (comprehensible at least - a message to a 0x0 object can not return any appropriate value~).
In the meantime I am really clueless what might be wrong, and I hope someone here might know what I am doing wrong or might have missed? :)
Best regards,
Uli
