Hey guys,
I was wondering what was the default values of variables before I intialize them ..
For example, if I do :
//myClass.h
BOOL myBOOL; // default value ?
NSArray *myArray; // default value ?
NSUInteger myInteger; // default value ?
Some more examples here :
//myClass.m
// myArray is not initialized, only declared in .h file
if ([myArray count] == 0) { // TRUE or FALSE ?
// do whatever
}
More generally, what is returned when I do :
[myObjectOnlyDeclaredAndNotInitialized myCustomFunction];
Thank you for your answers.
Gotye.
