Calling a method from an init method?

Let's say I have two properties defined as such:

@property (nonatomic, strong) UITableView *parentTableView;
@property (nonatomic, strong) NSMutableArray *headersArray;

and method:

-(void)prepareTags;

and say I have an init method like this:

-(id)initWithParentTableView:(UITableView*)parentTable
{
    if(self = [super init])
    {
        //1
        NSMutableArray *array = [[NSMutableArray alloc] init];
        headersArray = array;
        //2
        self.parentTableView = parentTable;
        //3
        [self prepareTags];
    }
    return self;
}
  • Is this the correct way to set up an array of headers in the init method?
  • Am I allowed to call self.parentTableViewfrom an init method?
  • I am allowed to call a method from the init method (in this case, the prepareTags method calls self). Will it be ready selfto use even if the init method has not yet returned?

Accordingly (I would use list formatting, but I can't get it to work with blockquotes ...!):

Is it correct to set up an array of headers in the init method?

, array, : headersArray = [[NSMutableArray alloc] init];

self.parentTableView init?

, Apple :

dealloc

. ivar ( headersArray)

init ( prepareTags self. self, init hasn ' t ?

. ( , , , , ..)

:

NSMutableArray *array = [[NSMutableArray alloc] init];
headersArray = array;

:

headersArray = [[NSMutableArray alloc] init];

self.parentTableView init?

, . , setter, . , ?

init?

The code looks good. Just a couple of notes ...

-(id)initWithParentTableView:(UITableView*)parentTable
{
    // avoid compiler warning about the assignment and the condition in the same statement
    self = [super init];
    if(self)
    {
        //1
        // no need for the extra stack variable
        self.headersArray = [[NSMutableArray alloc] init];

        //2
        // this is all fine from here
        self.parentTableView = parentTable;
        //3
        [self prepareTags];
    }
    return self;
}
