Question

 id delegate;

@property (nonatomic, assign) id  delegate;

I got this error; Existing ivar 'delegate' for unsafe_unretained property 'delegate' must be __unsafe_unretained

I tried changing the code to the following but i keep getting the same error.

__weak id delegate;

@property (nonatomic,weak) id  delegate;

When i change it to strong it works, But i don’t think that this is the correct way

id delegate;

@property (nonatomic,strong) id  delegate;

Answer 1

Try making the ivar unsafe-unretained as the compiler suggested.

{
    __unsafe_unretained id delegate;
}
@property(nonatomic, assign) id delegate;

Or just don’t declare the ivar, let the system generate it in @synthesize.
