Convert QString to NSString*

[BjoernK]

Hi all,

I'm working on an iOS app. I need to convert a QString to a NSString* but I can't figure out how it works. The following code produces a NSException:

@try
{
QString qs = "test";
NSString* nss = qs.toNSString();
NSLog(@"qs to ns: %@", [NSString nss]);
}
@catch (NSException *theException)
{
NSLog(@"An exception occurred: %@", theException.name);
NSLog(@"Here are some details: %@", theException.reason);
}

log output:

2016-07-25 13:58:13.676 MyApp[3832:1414942] +[NSString nss]: unrecognized selector sent to class 0x3b5b42dc
2016-07-25 13:58:13.677 MyApp[3832:1414942] An exception occurred: NSInvalidArgumentException
2016-07-25 13:58:13.677 MyApp[3832:1414942] Here are some details: +[NSString nss]: unrecognized selector sent to class 0x3b5b42dc

What do I miss?

Thank you in advance.

@BjoernK You can probably do it using NSString methods and then filter to QString
NSString reference

In particular, look at the "Getting C Strings" portion.

Hi,

If you want to log nss why not use NSLog(@"qs to ns: %@", nss); ?

Thank you for your replies.

@SGaist you're right - the string conversion is correct but the NSLog() call was wrong.

I should take a look at the objective C basics.
