NSString+URL.h
#import <Foundation/Foundation.h> @interface NSString (URL) -(NSString*)encodeString:(NSString*)unencodedString; -(NSString *)decodeString:(NSString*)encodedString; @end
NSString+URL.m
#import "NSString+URL.h" @implementation NSString (URL) //URLEncode -(NSString*)encodeString:(NSString*)unencodedString{ NSString *encodedString = (NSString *) CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)unencodedString, NULL, (CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8)); return encodedString; } //URLDEcode -(NSString *)decodeString:(NSString*)encodedString { NSString *decodedString = (__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL, (__bridge CFStringRef)encodedString,CFSTR(""), CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)); return decodedString; } @end
