Should self keyword should be used in init methods ?

[williamhqs]

I saw seems all places the properties was inited by the keyword self which wasn't recommended by Apple.

For example:

- (id)init {
    self = [super init];
    if (self) {
        self.walletService = [[Xxx alloc] initWithPresenter:nil];
    }
    return self;
}
