My oF iOS app gets wrong resolution on iPhone 6: 960x640. When I try the iosCustomSizeExample and choose “full” it gets a resolution of 1136x640. It should be 1334x750. On iPad mini retina it works fine and gets a resolution of 2048x1536 on both, my own app, and the iosCustomSizeExample. The reason I use the nightly build is because of the need of 64-bit support on the App store.
Source code for my app: https://github.com/stirem/BITWaves/tree/dev
The iPhone 6 will use the 320pt (640px) resolution if you have enabled the ‘Display Zoom’ in iPhone > Settings > Display & Brightness > View.
Else it will be 750.
(This is for all iOS apps)
Thanks for the reply, but I don’t think that is the reason. I have not found the source of the problem, but the app is now in App Store, and there it gets the right resolution. But not when I build directly from Xcode to phone. Maybe something with debug/release?
Check out the app, it’s free (no in-app, no ads): https://itunes.apple.com/us/app/bitwaves/id937814771?mt=8
Oh it was likely due to not having the Image Loading screens / LoadingScreen xib required for those devices until later when you were preparing for AppStore. Those are required for full native resolution of newer phones / devices. Should add them to template to prevent this.
Yes I confirm I’ve experienced what @danoli3 is saying few days ago,
just add launchImages at corresponding resolution in your project and your app will launch with correct resolution
I think I’m experiencing the same problem. I’m trying to use the iPhone 6’s full resolution to set the size of a video grabber and later draw it. When using ofGetWidth()/ofGetHeight(), I consistently get widths and heights of 375 and 667, respectively. When I set retina=true in main.mm, I get the correct resolution (w: 750 | h: 1334) but my grabber is scaled down.I have set up a launch image for every resolution as well. Am I missing something? Any pointers would be appreciated!
Example code (not much different from the videoGrabber example)
#include "ofApp.h"
//--------------------------------------------------------------
void ofApp::setup(){
//ofSetOrientation(OF_ORIENTATION_90_RIGHT);//Set iOS to Orientation Landscape Right
ofSetFrameRate(30);
ofBackground(255, 0, 0);
cout << "w: " << ofGetWidth() << " | h: " << ofGetHeight() << endl;
grabber.setup(ofGetWindowWidth(), ofGetWindowHeight(), OF_PIXELS_BGRA);
}
//--------------------------------------------------------------
void ofApp::update(){
grabber.update();
}
//--------------------------------------------------------------
void ofApp::draw(){
grabber.draw(0, 0);
}

I know it has been a couple of years since you’ve posted this, but by any chance, you’ve managed to solve it and remember a way in which you’ve done so? I’m stuck with the same problem and looking for ways to show ofVideoGrabber pixels full screen on my iphone5.
edit: Solved my issue
I have managed to solve a similar situation this using this example:
What I’ve learned in addition to that post was that AVFoundationVideoGrabber.innitGrabber(w,h) takes only specific camera formats such as 640x480, 1280x720 & others. I used 640x480 camera setup for my iPhone5 (screen size: 568x360), and when drawing, I offset it a little bit so that I would see most of the camera on the full screen, as in img.draw(-60,-31); It works quite well I must say.
