Create RTF file with Objective-C

I want to create an RTF file by creating my own source code of the RTF file and inserting in variables from my model.

I am creating the source coude using for example :

NSMutableString *body = [NSMutableString stringWithString:"{\rtf1\ansi\ansicpg1252\deff0\nouicompat\deflang3084\deflangfe3084{\fonttbl{\f0\froman\fprq2\fcharset0 Times New Roman;}{\f1\fswiss\fprq2\fcharset0 Calibri;}{\f2\froman\fprq2\fcharset2 Symbol;}}{\colortbl ;\red255\green255\blue255;\red0\green0\blue255;}{\*\generator Riched20 10.0.10240}\viewkind4\uc1\trowd\trgaph70\trleft-108\trbrdrl\brdrs\brdrw10 \trbrdrt\brdrs\brdrw10 \trbrdrr\brdrs\brdrw10 \trbrdrb\brdrs\brdrw10 \trpaddl70\trpaddr70\trpaddfl3\trpaddfr3\clbrdrl\brdrw10\brdrs\clbrdrt\brdrw10\brdrs\clbrdrr\brdrw10\brdrs\clbrdrb\brdrw10\brdrs \cellx2818\clbrdrl\brdrw10\brdrs\clbrdrt\brdrw10\brdrs\clbrdrr\brdrw10\brdrs\clbrdrb\brdrw10\brdrs"];

I want this string to be saved as an RTF file and then the RTF reader will conver this code to a readable RTF File. The problem is that Xcode gives me numerous errors (unknown escape sequence) due to the characters such as * \d \c \g . Moreover it says "Incomplete universal character name".

How can I have my NSString be treated like source code and ignore all those errors so that it can be parsed in an RTF file.

You need to escape your escape characters "\". When you write it to the console or file your string will output correctly.

NSMutableString *body = [NSMutableString stringWithString:@"{\\rtf1\\ansi\\ansicpg1252\\deff0\\nouicompat\\deflang3084\\deflangfe3084{\\fonttbl{\\f0\\froman\\fprq2\\fcharset0 Times New Roman;}{\\f1\\fswiss\\fprq2\\fcharset0 Calibri;}{\\f2\\froman\\fprq2\\fcharset2 Symbol;}}{\\colortbl ;\\red255\\green255\\blue255;\\red0\\green0\\blue255;}{\\*\\generator Riched20 10.0.10240}\\viewkind4\\uc1\\trowd\\trgaph70\\trleft-108\\trbrdrl\\brdrs\\brdrw10 \\trbrdrt\\brdrs\\brdrw10 \\trbrdrr\\brdrs\\brdrw10 \\trbrdrb\\brdrs\\brdrw10 \\trpaddl70\\trpaddr70\\trpaddfl3\\trpaddfr3\\clbrdrl\\brdrw10\\brdrs\\clbrdrt\\brdrw10\\brdrs\\clbrdrr\\brdrw10\\brdrs\\clbrdrb\\brdrw10\\brdrs \\cellx2818\\clbrdrl\\brdrw10\\brdrs\\clbrdrt\\brdrw10\\brdrs\\clbrdrr\\brdrw10\\brdrs\\clbrdrb\\brdrw10\\brdrs"];
