Having problems with adding objects to NSMutableArray

Question

I am having problem with adding objects to NSMutableArray *array.

//  Controller.m
#import \"Controller.h\"
@implementation Controller
- (void)parser:(NSString          


        

Answer 1

NSMutabaleArray starts at index 0

Answer 2

First off, you're over-retaining the array.

Second, you didn't provide the code for initializing the array, so I guess it's not allocated and initialized. This will cause the code to message a nil object and thus return nil.

You should create an init method for the Controller object, and allocate a new NSMutableArray object (and retain it).

Also, a proper dealloc to release the array.

Answer 3

Here is the method I added to Controller class:

- (id)init {
    self = [super init];
    if(self){
        array = [[NSMutableArray alloc] init];
    }
    return self;
}
- (void)dealloc {
    [array release];
    [super dealloc];
}
