can you return from a method early in an objective-c?

Question

I'm doing some networking stuff in one of my methods and I would like the method to return NO and stop executing early if one of the internal calls returns an error, a bit like break for loops. Is this possible?

IMO it would produce cleaner code rather than using a BOOL flag and having "should I continue executing this code?" if statements all over the place; and then finally at the end of the method returning YES or NO based on the flag.

Any thoughts are much appreciated!

Answer 1

Yes, you can.

return NO;

Return statements are acceptable everywhere in functions and methods. I personally prefer to make use of early returns because it usually leads to less nesting (and thus code easier to understand).

There are several similar questions around here:

• Should I use early returns in C#?
• Is it bad to have multiple return statements?
• Should a function have only one return statement?
