Does anyone know of an easy way to add a single backslash () to an NSString in Objective-C?
I am trying to add a backslash between each byte of addresses. But after adding and printing the output is not coming as expected.
Output: "<IpAddress 0x00000002834809d0>" = { FourByteAddress = "0/\0/\0/\0"; };
Expected: "<IpAddress 0x00000002834809d0>" = { FourByteAddress = "0\0\0\0"; };
Can you post more details about your specific problem? I wrote some code to do this (see below) and it works just fine but I suspect that I’m missing some key element of the problem.
NSString * address = @"1.2.3.4";
NSArray * components = [address componentsSeparatedByString:@"."];
NSString * quotedAddress = [components componentsJoinedByString:@"\\."];
NSLog(@"%@", quotedAddress);
// prints: … 1\.2\.3\.4
Share and Enjoy
