editing occurrences is not working

i am trying to get the path to a certain file
and then open it in a webview. so i need to replace each space by '%20'

NSString *test=@"filename";
NSString *finalPath12 = [test stringByAppendingString:@".pdf"];

NSString *path1 = [[NSBundle mainBundle] bundlePath];
NSString *finalPath1 = [path1 stringByAppendingPathComponent:finalPath12];

NSString *file =@"file://";
NSString *htmlfilename1 = [file stringByAppendingString:finalPath1];

NSString *pathtofile = [htmlfilename1 stringByReplacingOccurrencesOfString:@" " withString:@"%20"];

any string is working except @"%20".

this works perfectly for exemple:

NSString *pathtofile = [htmlfilename1 stringByReplacingOccurrencesOfString:@" " withString:@"string"];

but i need the @"%20". What am i missing ? Thanks

There is already [NSString stringByAddingPercentEscapesUsingEncoding:] (reference) for that very purpose.

However in your case, as you want a URL, you can replace all the lines in your question with:

NSURL *url = [[NSBundle mainBundle] urlForResource:@"filename" withExtension:@"pdf"];

You need to use @"%%20".

As first % is treated as escape/wild character.

Or use

stringByAddingPercentEscapesUsingEncoding:
