objective c - backScalingFactor on Retina display not showing 2.0 -


here's code i'm using backing scale factor window:

gcfloat backingscalefactor = [[nsscreen mainscreen] backingscalefactor]; nslog(@"scale factor %.2f", backingscalefactor);

and have in info.plist:

<key>nshighresolutioncapable</key> <true/>

i've tried putting different variations of above in info.plist also, these:

<key>nshighresolutioncapable</key> <string>true<string>

and

<key>nshighresolutioncapable</key> <string>true<string>

i still don't correct backingscalefactor, though i'm on retina display. have app give me 2.0 backingscalefactor, i'm wondering if there else i'm missing?
