Make an NSURL with an encoded plus (+)

Question

I need to pass a timestamp with a timezone offset in a GET request, e.g.,

2009-05-04T11:22:00+01:00

This looks like a two arguments

Answer 1

The string should be URL encoded.

Here is a category for NSString that will help:

NSString+Additions.h

@interface NSString (Additions)

- (NSString *)stringByURLEncoding;

NSString+Additions.m

#import "NSString+Additions.h"

@implementation NSString (Additions)

- (NSString *)stringByURLEncoding {
    return (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
                                                           (CFStringRef)self,
                                                           NULL,
                                                           (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",
                                                           CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
}
