Question

I have this class:

@interface RSSEntry : NSObject{
    NSString *blogTitle;
    NSString *articleTitle;
    NSString *articleUrl;
    NSDate *articleDate;
}

@property (copy) NSString *blogTitle;
@property (copy) NSString *articleTitle;
@property (copy) NSString *articleUrl;
@property (copy) NSDate *articleDate;

@end

Now, how will I make these member variables get initialized when creating an object, especially when ARC is enabled in the Xcode project? I’m new to Objective-C; I’m looking for something like constructor from C base languages.

Answer 1

In Objective-C there are no constructors. However, it is a common practice to create init method and have users call alloc immediately followed by init. See Objective-C constructors for example.
