I am new to iPhone development. I want a Nsmutable array to hold numbers from 1 to 100. How can I do it? How can I implement in a for loop? Is there any other way to hold numbers in array in iPhone?

You can only add NSObject subclasses in Cocoa containers. In your case, you will have to wrap your integers in NSNumber objects:
NSMutableArray *array = [NSMutableArray array];
for( int i = 0; i < 100; ++i )
{
[array addObject:[NSNumber numberWithInt:i]];
}
To extract the values:
int firstValue = [[array objectAtIndex:0] intValue];

any idea how we would remove a number added this way if we dont know the index? im trying to use [array removeObjectIdenticalTo:i]; i have also tried [array removeObjectIdenticalTo:[i intValue]] and [array removeObjectIdenticalTo:[NSNumber numberWithInt:i]]
Use an NSNumber object:
[NSNumber numberWithInt:1];

I am a newbie, can u give more code,of how u save the values in a array.Thanks.
The short hand solution
NSMutableArray *array = [NSMutableArray array];
for( int i = 0; i < 100; ++i )
{
[array addObject:@(i)];
}
int intValue = 10;
NSNumber *numberObj = @(intValue);
