iOS About [NSArray alloc] initWithObjects: problem

[andyiapan]

if i got an id *object
object[size] may be 20000,
but i want to

NSArray *listContent = [[NSArray alloc] initWithObjects:
[Product productWithTypebjects[i+1] namebjects]
........
,nil];

how can i alloc all the objects in a listContent, i can't find out this use a for loop, thx

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"a" ofType:@"txt"];
	id *objects;
	int i=0;
		
		NSString *myText = [NSString stringWithContentsOfFile:filePath];  
		
  
			
			int stringLength = [myText length];
			NSRange range = NSMakeRange(0, stringLength);
			NSString *newStr = [myText stringByReplacingOccurrencesOfString:@"\n" withString:@"	" options:NSCaseInsensitiveSearch range:range];
			
			
			NSArray *listItems = [newStr componentsSeparatedByString:@"	"];
			
			
			NSUInteger count = [listItems count];
			
			objects = malloc(sizeof(id *) * count);
			
			[listItems getObjects:objects];

		NSArray *listContent = [[NSArray alloc] initWithObjects:
							[Product productWithType:objects[i+1]  name:objects[i]],nil];

if i want to initWithObjects:  
productWithType:objects[1]  name:objects[0]],
productWithType:objects[3]  name:objects[2]],
........,nil];

i need to input one by one,
but i got objects[20000], can i use i for loop or other methods to initWithObjects? ThX

First of all please use the CODE bbtag for the code.
The "id" tag is the pointer to the object. You don't need to create a id*, unless you want a pointer to a pointer.
Why exactly are you using this line?

 objects = malloc(sizeof(id *) * count);

You could just use a NSMutableArray and add Objects to it.
like so.

NSMutableArray *array = [NSMutableArray];
for (int i=0; i< 15; i++)
{
   [array addObject:[MyClass constructorWithString:@"String"]];
}

And to access objects in an array use the objectAtIndex method.
Like so.

Class *myObject = [array objectAtIndex:8];

or

id myObject = [array objectAtIndex:8];

They both do the same thing

i want to load a text file that content is
123456 A
324123 B
687678 C
23 D
111111 E
as i see want to separated number and Text
when i input number 1 , it will show A and E,
12, it will show A, 123456 also A,

as i want to build a apps like that but i feel frustrate.
and i just use TableSearch example as reference but comes out many problem

any searching algorithm or access text file(database) example
that i can as reference in the above case? THX
