$createArray = array ();
for ($i = 0; $i<10; $i++) {

Answer 1

Save your values in NSDictionary and add that dictionary into your array
NSMutableArray *theArray = [NSMutableArray array];
for (int indexValue = 0; indexValue<10; indexValue++) {
NSMutableDictionary *theDictionary = [[NSMutableDictionary alloc] init];
[theDictionary setObject:name forKey:#"name"];
[theDictionary setObject:age forKey:#"age"];
[theArray addObject:theDictionary]
}
While Retrieving time,
NSString *name = [[theArray objectAtIndex:indexValue] objectForKey:#"name"];
NSString *age = [[theArray objectAtIndex:indexValue] objectForKey:#"age"];

you might find it helpful:
array = [[NSMutableArray alloc] init];
for (int i = 0; i < 8; i++) {
NSMutableArray *subArray = [[NSMutableArray alloc] init];
for (int j = 0; j < 8; j++) {
[subArray addObject:[NSNumber numberWithInt:0]];
}
[array addObject:subArray];
[subArray release];
}

Try this.
array = [[NSMutableArray alloc] init];
for (int i = 0; i < 10; i++) {
NSMutableArray *subArray = [[NSMutableArray alloc] init];
for (int j = 0; j < 2; j++) {
//Do your Stuff
// [subArray addObject:name];
// [subArray addObject:Age];
}
[array addObject:subArray];
}
OR
Why can't try with the NSDictionary

Answer 4

You can use this. But this is not better way in IOS.
NSMutableArray *array[20];
for (int i=0;i< 20; i++)
{
array[i] = [NSMutableArray array];
for (int j=0;j<3;j++)
{
NSMutableDictionary *theDictionary = [[NSMutableDictionary alloc] init];
[theDictionary setObject:name forKey:#"name"];
[theDictionary setObject:age forKey:#"age"];
[[array[i] addObject:theDictionary]
}
}

First you to have set An NSMutableDictionary on .h file
#interface MSRCommonLogic : NSObject
{
NSMutableDictionary *twoDimensionArray;
}
then have to use following functions in .m file
- (void)setValuesToArray :(int)rows cols:(int) col value:(id)value
{
if(!twoDimensionArray)
{
twoDimensionArray =[[NSMutableDictionary alloc]init];
}
NSString *strKey=[NSString stringWithFormat:#"%dVs%d",rows,col];
[twoDimensionArray setObject:value forKey:strKey];
}
- (id)getValueFromArray :(int)rows cols:(int) col
{
NSString *strKey=[NSString stringWithFormat:#"%dVs%d",rows,col];
return [twoDimensionArray valueForKey:strKey];
}
