[window deviceDescription] is to return an NSDictionary of device
description data
NSDeviceResolution key is to return an NSString representing an NSSIze
Calling NSSizeFromString on this returned string causes and exception
-[NSConcreteValue getCString:maxLength:encoding:]: unrecognized
selector sent to instance 0x130165e0
here is the code
- (NSSize)deviceDPI {
NSDictionary* dd = [m_window deviceDescription];
NSString* v = [dd valueForKey:NSDeviceResolution];
NSSize sz = NSSizeFromString(v);
return sz;
}
v is @"{72, 72}" when print-object is called on it in the debugger
I do not see anything wrong with the code ... do you?
