If I create property, for example:
@property NSString *selectedSubProductId;
and create setter and getter:
- (NSString *)selectedSubProductId {}
- (void)setSelectedSubProductId:(NSString *)value_ {}
XCode says that "Deault property attribute 'assign' not appropriate for non-gc object". Do attributes have any meaning in this case? Does it matter if i make them copy or assign or are they only cue for @synthesize to create desired methods? If so, how should I disable the warnings?
If it is object, you should use retain/copy property modifier.
For example:
@property (nonatomic, retain) NSString *selectedSubProductId;
If the modifiers are missing, assign modifier is enabled by default. But it is only valid for scalar (int, float...) or struct.
You may get more details in Apple Documentation
That warning says that you are using a default property atribute (assign) because you forgot to say how do you want to hold your object.
If you want to "remove" the warning use a retain/copy property:
@property (copy) NSString *selectedSubProductId;
However, in Strings you should use copy. For more information please visit this question on stackoverflow.
