NSString Format issue automatically append \x

Question

i found something like this was not expected

code

NSString *strCrown2 = @"T-#-B-DAC";

when i put break point there and check i found like below image

There is \x , it is not part of string

in console it is displaying T-#-B-DAC it is correct

my question is why \x is showing there ?

I dont think that create any problem the po output is : correct that what you want — Nitin Gohel, Apr 26 '16 at 07:59

Because # is for prefix of hex color

You can solve it by escape sequence

NSString *strCrown2 = @"T-\#-B-DAC";

strCrown2 = [strCrown2 stringByReplacingOccurrencesOfString:@"\#" withString:@"200"];//outout:@"T-200-B-DAC"

You can also only # not considering '\x' value like the below

 NSString *strCrown2 = @"T-#-B-DAC";
 strCrown2 = [strCrown2 stringByReplacingOccurrencesOfString:@"#" withString:@"200"];//outout:@"T-200-B-DAC"

Does it create problem in future ? – Prashant Tukadiya Apr 26 '16 at 07:54
you need to add \# for printing # as a string – Jamil Apr 26 '16 at 07:57
why you worried about NSLog the string object that you want that show the correct output then why you worried? – Nitin Gohel Apr 26 '16 at 08:03

Edit :- I got your solution , you can't able to see but , try to delete "-" before # , it will first delete one space and then your "-" will be deleted. so, it will take one white space before #

And, According to apple document , check

NSRegularExpression

so, it will take white space before # just delete it once you will get desire output when you debug.

I hope this info will be helpful for you.

Edit :-

Write this in your x-code ,

NSString *strCrown2 = @"T-#-B-DAC";

The \x is used for hexadecimal representation of a number.

I have tried same string, may be you are not using x-code 7. I am not getting as like you , i think it is showing the unicode string. you can add the string in the info.plist . it will work.
