问题 I have a page that I need to reset the viewport scale (the pinch zoom) on command, setting it back to the initial zoomed out state. Looks like the old tried and true method of rewriting the meta viewport: const viewportmeta = document.querySelector('meta[name="viewport"]'); viewport.attr('content', "initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0"); doesn't seem to have any effect anymore on ios10 (page remains zoomed in).

问题 Apple's Photo app has facial recognition capabilities. I would like to know if an API exists to access the associated data for photos which have been classified by the app. (tagged with API, not sure which tags.) Thanks! 回答1: Apple released an SDK for accessing Apple Photos called Photo Kit. In the documentation, you will find API access to the photos application and photos cloud.

问题 I'm experiencing a weird behaviour with NSFetchedResultsController. It is new in iOS 10. Straight to the point: fetchedObjects contains duplicate objects.

How does it happen in my app: FRC is setup and fetch performed 2 objects are fetched (in this example) Something happens in my sync layer, another object (that fetch items are in relationship with) is updated FRC calls
