I think this helps you

NSArray *namesArray = @[@"anju",@"chandu",@"basha",@"chitra",@"amith",@"baskar"];
NSMutableArray *aArray = [[NSMutableArray alloc]init];
NSMutableArray *bArray = [[NSMutableArray alloc]init];
NSMutableArray *cArray = [[NSMutableArray alloc]init];
for (int j=0; jNSString *string = [namesArray objectAtIndex:j];
        if ([string hasPrefix:@"a"]) {
            [aArray addObject:string];
        }else if([string hasPrefix:@"b"]){
            [bArray addObject:string];
        }else if([string hasPrefix:@"c"]){
            [cArray addObject:string];
        }
}
NSLog(@"---%@----%@----%@",aArray,bArray,cArray);

Try this..

for(int i =;i<names.length;i++){
   NSString *myString =names[i];
   NSString *subString = [myString substringWithRange: NSMakeRange(0, 1)];
   if([subString isEqualToString:@"a"){
     [as addObect:subString];
   }else if([subString isEqualToString:@"b"){
     [bs addObect:subString];
   }else if([subString isEqualToString:@"c"){
     [cs addObect:subString];
   }
}
