NSString, problem to create

I have a problem with creation to NSString. The error is: "error: expected ']' before numeric constant". The code is below. Can you help me to find a solution for create these?

You need to escape the quotes in your string. Try it like this

NSString *titleXML = [NSString  stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"];

---

You have quote characters embedded in your string, you need to escape them with backslash like this:

NSString *titleXML = [NSString  stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"];

---

You have to escape your double quotes in the string using \":

NSString *titleXML = [NSString  stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"];

You'll need to escape those double quotes in the string for it to work. Like so:

NSString *titleXML = [NSString  stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"];
