NSString to QString

[ABBAPOH]

How can i convert NSString to QString? Or, better NSUrl to QUrl or QString
I found inline function qt_mac_NSStringToQString, but i can't use it because headers are private and not installed on Mac by default. Besides, they use inncludes in form of "header.h" (#include <qapplication.h>) which are not seen to compiler too.

Safe variant:

QString qt_mac_NSStringToQString(const NSString *nsstr)
{
    NSRange range;
    range.location = 0;
    range.length = [nsstr length];
    QString result(range.length, QChar(0));
 
    unichar *chars = new unichar[range.location];
    [nsstr getCharacters:chars range:range];
    QString result = QString::fromUtf16(chars, range.length);
    delete  chars;
    return result;
}

QString qt_mac_NSStringToQString(const NSString *nsstr)
{
    NSRange range;
    range.location = 0;
    range.length = [nsstr length];
    QString result(range.length, QChar(0));

    unichar *chars = new unichar[range.location];
    [nsstr getCharacters:chars range:range];
    QString result = QString::fromUtf16(chars, range.length);
    delete  chars;
    return result;
}

To copy to clipboard, switch view to plain text mode 

Unsafe variant (a little faster):

QString qt_mac_NSStringToQString(const NSString *nsstr)
{
    NSRange range;
    range.location = 0;
    range.length = [nsstr length];
    QString result(range.length, QChar(0));
 
    unichar *chars = reinterpret_cast<unichar *>(result.data())
    [nsstr getCharacters:chars range:range];
    return result;
}

QString qt_mac_NSStringToQString(const NSString *nsstr)
{
    NSRange range;
    range.location = 0;
    range.length = [nsstr length];
    QString result(range.length, QChar(0));

    unichar *chars = reinterpret_cast<unichar *>(result.data())
    [nsstr getCharacters:chars range:range];
    return result;
}

Any suggestions?
