Want to learn Objective-C but syntax is very confusing
- by Sahat
Coming from Java background I am guessing this is expected. I would really love to learn Objective-C and start developing Mac apps, but the syntax is just killing me.
For example:
-(void) setNumerator: (int) n
{
numerator = n;
}
What is that dash for and why is followed by void in parenthesis? I've never seen void in parenthesis in C/C++, Java or C#. Why don't we have a semicolon after (int) n? But we do have it here:
-(void) setNumerator: (int) n;
And what's with this alloc, init, release process?
myFraction = [Fraction alloc];
myFraction = [myFraction init];
[myFraction release];
And why is it [myFraction release]; and not myFraction = [myFraction release]; ?
And lastly what's with the @ signs and what's this implementation equivalent in Java?
@implementation Fraction
@end
I am currently reading Programming in Objective C 2.0 and it's just so frustrating learning this new syntax for someone in Java background.
