unrecognized selector sent to instance when no related entities found in Core Data

I have a Core Data problem - I have two entity's with the second being a one to many relation ship to the first. When trying to load a detailed view controller on the first with the first one's information and a UITableView fo the details of the 2nd, I am hoping this tableView code would allow me to show a blank table if now records are found. Instead I get a crash as indicated above. I have tried to cover the "Event" (the related NSSet) into an array, but I am not sure how to debug this error. Thanks for any pointers! func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath)

xcode Simulator delays the displaying of a page

Upgraded to XCode 9.2 and now my app behaves badly on the ios simulator. It still runs ok when deployed to a physical device. The problem is that pages are taking from 10secs to 1 minute to refresh. eg after a tableview.reloadDate(). I am certain the reloading of the data is occurring immediately, it just that the page isn't being displayed until after a long delay Interestingly if I tap the simulator screen the response is as if I tapped the refreshed (but as yet undisplayed) page. I don't think this is an animation issue, I have made sure that in the simulator Debug menu that 'Slow

How can I get Camera Calibration Data on iOS? aka AVCameraCalibrationData

由 做~自己de王妃 提交于 2019-12-02 07:15:40
As I understand it, AVCameraCalibrationData is only available over AVCaptureDepthDataOutput. Is that correct? AVCaptureDepthDataOutput on the other hand is only accessible with iPhone X front cam or iPhone Plus back cam, or am I mistaken? What I am trying to do is to get the FOV of an AVCaptureVideoDataOutput SampleBuffer. Especially, it should match the selected preset (full HD, Photo etc.). rickster You can get AVCameraCalibrationData only from depth data output or photo output. However, if all you need is FOV, you need only part of the info that class offers — the camera intrinsics matrix —

问题 My CSS style sheet appears to be working fine but I'm not able to change the font to one that closely matches the System font used in iOS 11.
