Is there a similar method in Objective-C for encoding URI components?
http://www.w3schools.com/jsref/jsref_encodeuricomponent.asp
This is a common task, but I am unable to locate any documentation specific to Objective-C.
Appreciate any insights.
provides an easy solution for this task.-[NSString stringByAddingPercentEscapesUsingEncoding:]
Sure, feel free to utilize these methods. I believe they will be beneficial.
//encode URL string
+(NSString *)URLEncodedString:(NSString *)str
{
NSString *encodedString = (NSString *)
CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,
(CFStringRef)str,
NULL,
(CFStringRef)@"!*'();:@&=+$,/?%#[]",
kCFStringEncodingUTF8));
return encodedString;
}
}
//decode URL string
+(NSString *)URLDecodedString:(NSString *)str
{
NSString *decodedString=(__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL, (__bridge CFStringRef)str, CFSTR(""), CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
return decodedString;
}
There has been a deprecation of the method
stringByAddingPercentEscapesUsingEncoding:encodeURIComponent:
[str stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]
Avoid using the deprecated methods
CFURLCreateStringByAddingPercentEscapesstringByAddingPercentEscapesUsingEncodingAlthough Dave's answer is on the right track, it lacks specificity.
Instead of using
NSCharacterSet.URLQueryAllowedCharacterSetencodeURIComponent():
A–Z a–z 0–9 - _ . ! ~ * ' ( )
Here is an improved solution:
+ (NSString *)encodeURIComponent:(NSString *)uriComponent {
NSString *allowedChars = @"ABCDEFGHIJKLMNOPQRSTUVWXYZ"
"abcdefghijklmnopqrstuvwxyz"
"0123456789"
"-_.!~*'()";
NSCharacterSet *charSet = [NSCharacterSet characterSetWithCharactersInString:allowedChars];
return [uriComponent stringByAddingPercentEncodingWithAllowedCharacters:charSet];
}
+ (NSString *)decodeURIComponent:(NSString *)uriComponent {
return [uriComponent stringByRemovingPercentEncoding];
}
