Get a Substring by Char Index and Length

Demonstrates how to use the GetRange method to get a substring by index and length.

Note: This example demonstrates the GetRange method which was added in Chilkat v9.5.0.87.

Objective-C

#import <CkoStringBuilder.h>
#import <NSString.h>

BOOL success = NO;

CkoStringBuilder *sb = [[CkoStringBuilder alloc] init];

//  Load a file that contains this string:  0123456789ABCDEF
success = [sb LoadFile: @"qa_data/txt/remove_chars.txt" charset: @"utf-8"];

//  Return "56789A" from the string.
//  if removeFlag is true, the returned string is also removed from the sb.
BOOL removeFlag = YES;
NSString *result = [sb GetRange: [NSNumber numberWithInt: 5] numChars: [NSNumber numberWithInt: 6] removeFlag: removeFlag];

NSLog(@"%@",result);
NSLog(@"%@",[sb GetAsString]);

//  Output is: 
//  
//  56789A
//  01234BCDEF
