Answer 1

Use (__bridge_transfer NSString *) instead of (__bridge NSString *)

With ARC, you can use __bridge_transfer to transfer memory management of the returned string to ARC

Example:

NSString *myString = [self encodeURL:@"hi*)"];
NSLog(@"%@",myString);

-(NSString *)encodeURL:(NSString *)string{

    NSString *newString = @"";        
    newString = (__bridge_transfer NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (__bridge CFStringRef)string, NULL, CFSTR("^%*)*&%$"),CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));              
    return newString;

}
