问题 Is there a workaround for value(for component: Calendar.Component) seemingly being broken? Or a dynamic way to call the property version? func dateComponentsValueShouldBeNil() { let dateComponents = DateComponents(month: 3) debugPrint("Month", dateComponents.month) // "Month" Optional(3) debugPrint("Property", dateComponents.hour) // "Property" nil debugPrint("Enumeration", dateComponents.value(for: .hour)) // "Enumeration" Optional(9223372036854775807) } 回答1: Non-defined date components in a

问题 I have an app that been happily shipping for a couple of years. It retrieves RSS Feeds in a UICollectionView. The cellForItemAtIndexPath method sets text and calls a datasource method to load an image from a link specified in the feed. If none exists it loads the web page data and searches for <img> tags to get an image. Once the image is found/loaded the delegate method is called to add the image to the cell. (below) When running in iOS 8 and 9 everything is happy, but when running in iOS 10

问题 I am confused if 'Vary for Traits' is the right thing to define different set of layout constraints for Portrait & Landscape mode on iPhone. My objective is to have different layouts for Portrait & Landscape modes on the iPhone (doesn't matter on iPad). I tried 'Vary for Traits' and define different set of NSLayoutConstraints for Portrait & Landscape modes but it seems to be not working. Basically if I have constraints P1 & P2 active for portrait mode and C1 & C2 for landscape mode for the

问题 I have tried to add a banner notification generator to my macOS swift app and the banner does not appear when test running in XCode and neither are there any new notifications visible in the notification centre. Other apps on my computer are generating notifications regularly. What have I missed?
