Append a newline to an NSString

Question

I have this:

if (soapResults != nil) {
    soapResults = [soapResults stringByAppendingString:@"\n"];
    }

But I get a warning:

Assignment from distinct Objective-C type on build.

When I run it on device I get:

Program received signal: "EXC_BAD_ACCESS".

from gdb.

Any ideas how to append a newline to an NSString without getting a warning or error?

Any help appreciated // :)

Answer 1

An alternative is: [NSString stringWithFormat: @"%@\n", soapResults] even if the logic is the same!

However, even in the case of stringByAppendingString, it returns a new string but it doesn't change the target, so you have to assign the new string to a new instance of the class NSString.

Answer 2

You can try this, it works for me:

NSString *content1 = [messageObject valueForKey:@"content"];
NSString *seprator = @"\n----------------------\n";
NSString *myString = [NSString stringWithFormat:@"%@\n%@\n",seprator,content1];
content = [content stringByAppendingString:myString];
