Hi everyone! First post to the list!
I'm in ch 6 of Learning Cocoa (where we are building Cocoa Foundation
Tools)
and it tells me to use NSLog all over the place but when I went to
option
click it for documentation it wasn't there. After some more directed
searching I couldn't find it ether.
Look here
file:///System/Library/Frameworks/Foundation.framework/Versions/C/
Resources/English.lproj/Documentation/Reference/ObjC_classic/Functions/
FoundationFunctions.html
(search for NSLog)
My main is below, and here are my questions:
1) Is NSLog() an object? If so, why does option clicking it not return
information?
Its a function
2) Where is info. In particular the book tells us to use the following
line
to get the value inside of an array:
NSLog(@"Array desctiption: %@ items.\n", myArray);
But when I try to out my "itemcount" in a similar fashion:
NSLog(@itemcount);
-or-
NSLog(itemCount);
It get errors :-(
I think in general I'm looking to replicate something similar to this
C++
code that I've been writing.
cout << "The number of items in my array are: " << itemCount << endl;
thanks in adv. for all your help,
~ Mike, a lowely web guy working his way into platform coding.
My main:
#import <Foundation/Foundation.h>
int main (int argc, const char * argv[]) {
// init
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSMutableArray *myArray;
NSString *myString;
int itemCount;
// start code
NSLog(@"Hello, World!");
myArray = [[NSMutableArray alloc] init];
NSLog(@"Array desctiption: %@ items.\n", myArray);
[myArray addObject: @"Here's a string!"];
[myArray addObject: @"Here's a another string!"];
NSLog(@"Array desctiption: %@ items.\n", myArray);
itemCount = [myArray count];
// NSLog(@itemcount);
// NSLog(itemCount);
[myArray release];
[pool release];
return 0;
}
