Return NSString from a C function
advertisements
In iOS development, is it possible to use NSString and return it from a function?
(NSString * ) foo {
return @"";
}
This is not an objective c method, just function
Yes, seeing as objective-c objects are just pointers, you can create a C function to return one:
NS_RETURNS_RETAINED NSString *myFunction() {
return [[NSString alloc] init];
}
Notice the use of NS_RETURNS_RETAINED. This is a hint to ARC and the static analyzer that this function returns a retained value to the receiver, and that it's their responsibility to release it.
If you were returning an autoreleased value, try using NS_RETURNS_NOT_RETAINED instead.
