Remove a Range of Chars from a StringBuilder

Demonstrates how to remove a range of chars from the string contained in a StringBuilder object.

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

Objective-C

#import <CkoStringBuilder.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"];

//  Remove "56789A" from the string.
[sb RemoveCharsAt: [NSNumber numberWithInt: 5] numChars: [NSNumber numberWithInt: 6]];

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

//  Output is: 01234BCDEF
