objective c - Cannot strip newline from Cocoa NSMutableString -

Hey, for my life, it's not working: ..

  NSMutableString * B64String = [[[NSMutableString alloc] initWithFormat: @ "Basic% @", [string_base64 encoding: string]] autorege]; [B64 string string bitimating customer inset: [NSCRTitreatersSatNewelCarCarSat]]; NSLog (@ "(% @)", B64 string); NSRange found range = [b64String rangeOfString: @ "\ n"]; If (foundRange.location! = NSNotFound) [B64 string stringearplying ocransoffstring: @ "\ n" with string: @ "" option: 0 range: mixed range]; NSLog (@ "(% @)", B64 string);  

In both the ways that I found - and they do not work ... I have to do something wrong. But, if I break on NSLog, I can clearly see "\ n" (in the debugger and in the console) in the string

Besides, this is true:

  If (foundRange.location! = NSNotFound)  

and I can see that string bayer rehearsing octersonationofstrings method ...

Just call

  b64String = [b64String stringByReplacingOccurrencesOfString: @ "\ n" with string: @ "" ]  

is sufficient ( -release to b64strin G . You want to store it in another variable), or you can actually use the completely unstable method Category:

  [ B64String replaceOccurrencesOfString: @ "\ n" with string: @ "" option: 0 category: nsmkrange (0, [b64 string length]]];  -stringByReplacingOccurrencesOfString: withString: Option: Category: ,  category  parameter specifies the category where the replacement occurs. In  

This means that nothing will change outside the boundary. In your code, you pass the first format of the \ n only the 1 event of the effect \ n will be deleted.

string By ... Methods that are for an unchanging string will not modify the input string. Instead, they copy the irreversible string and return the modified copy.
