componentsSeparatedByString:@"\r\n" does not work on NSString

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
NSString *URLString = [[url absoluteString] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSArray *temp = [URLString componentsSeparatedByString:@"\r\n"];
return YES;}

that does not split the string, though preview shows \r\n are still in the string. Any suggestions?

input URL sample- myapp://bla\r\nbla

here is string after replacing % esc and splitting by '\r\n':

here is url before replacing % esc:

I suspect replacing percent escapes has got to do something with it.

As per Eduardo but closer to your code, the following:

NSString *URLString = @"myapp://bla\r\nbla";
NSArray *temp = [URLString componentsSeparatedByString:@"\r\n"];
NSLog(@"%@", temp);

Outputs:

2014-03-20 12:05:17.247 Untitled 3[437:507] (
    "myapp://bla",
    bla
)

Is it possible your incoming string contains the literal four-character sequence \r\n, which would be written as @"\\r\\n" rather than the sequence of two control codes, \r\n?
