(Objective-C) 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.
#import <CkoStringBuilder.h>
#import <NSString.h>
CkoStringBuilder *sb = [[CkoStringBuilder alloc] init];
// Load a file that contains this string: 0123456789ABCDEF
BOOL success = [sb LoadFile: @"qa_data/txt/remove_chars.txt" charset: @"utf-8"];
// Return "56789A" from the string.
// if removeFlag is YES, 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
// 01234BCDE
