Correct bridging for ARC?

Question

I have a category class for NSString.

@implementation NSString (URLEncode)

- (NSString *)URLEncodedString
{
    __autoreleasing NSString *encodedString;

          


        

Answer 1

-(NSString *) urlEncoded
{
    CFStringRef encodedCfStringRef = CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)self,NULL,(CFStringRef)@"!*'\"();@+$,%#[]% ",kCFStringEncodingUTF8 );
    NSString *endcodedString = (NSString *)CFBridgingRelease(encodedCfStringRef);
    return endcodedString;
}
