Question

I have declared a NSMutable Array with 50 size. As i want to use each index as an array and add data separately. e.g i want to add 10 object to first Index 5 to next and so on.
Is this the right way to do it? Please help me out if there is an alternate way.The sdk gives me error at line 5 saying ‘Cannot convert to a pointer type’.

NSMutableArray *myArray[50];    
@property (nonatomic, retain) NSMutableArray *myArray;            
@dynamic myArray; 
for (int i = 0; i < count; i++)     
{                                   
    myArray[i] = [NSMutableArray alloc];         
}

PresentationSlides[i] addObject:string];

My problem is how can i reach to a specific index.if i use this.

for (int i = 0; i < count; i++)     
{                                   
myArray = [NSMutableArray array];    
}         
[myArray objectAtIndex:i ??????   

What else?
I am stuck in the projet after completing 90% of it. And there is no use of it if i couldnt complete it.

You’ll have to allocate myArray:

myArray = [NSMutableArray arrayWithCapacity:50];

Then for line 5, in the loop, ‘alloc’ alone isn’t enough. Try:

[myArray insertObject:[[NSMutableArray alloc] initWithCapacity:10] atIndex:i];
