objective c - will auto synthesize with @property(copy) NSString *string do auto copy? -


say if have property arc , auto-synthesize:

@interface a: nsobject @property (nonatomic, copy) nsstring *name; @end

now when using property, copy automatically, or have manual copy?

like

a *a = [a new]; nsstring *str = @"hello"; a.name = str; // or a.name = [str copy]?

marking property copy work mutable instances.
don't need copy immutable instances (like nsstring).
