I have UTF-8 encoded NSData
from windows server and I want to convert it to NSString
for iPhone. Since data contains characters (like a degree symbol) which have different values on both platforms, how do I convert data to string?
If the data is not null-terminated, you should use -initWithData:encoding:
NSString* newStr = [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];
If the data is null-terminated, you should instead use -stringWithUTF8String:
to avoid the extra \0
at the end.
NSString* newStr = [NSString stringWithUTF8String:[theData bytes]];
(Note that if the input is not properly UTF-8-encoded, you will get nil
.)
let newStr = String(data: data, encoding: .utf8) // note that `newStr` is a `String?`, not a `String`.
If the data is null-terminated, you could go though the safe way which is remove the that null character, or the unsafe way similar to the Objective-C version above.
// safe way, provided data is \0-terminated let newStr1 = String(data: data.subdata(in: 0 ..< data.count - 1), encoding: .utf8) // unsafe way, provided data is \0-terminated let newStr2 = data.withUnsafeBytes(String.init(utf8String:))
