问题 I have an iOS app in which I am setting a custom navigation title view. It was working fine till iOS 10, but in iOS 11 the navigation title view is misplaced. Here is the screen shot for iOS 10 - Here is the screen shot for iOS 11 - As you can see in the screen shots that when I run the code on iOS 10 the title view appears to be fine. But the same code on iOS 11 shifts the title view down by some pixels and it gets cut. This is how I am setting the title view - navigationItem.titleView = MY

问题 I understand that this question has been asked many, many times on SO. However, as Apple does best, with the release of iOS 11 , they seem to have made a seemingly unnecessary change to the UISearchBar , specifically it's view hierarchy.

问题 Creating some new view controllers with xcode 9 so now I have a few safe areas to deal with. I am currently trying to do something fullproof, meaning keeping the unsafe area as it is (since I always display the status bar) and having the background color extending to the fullscreen (to keep a similar behaviour to what I used to have). On an additional note, this also affect page controls since when you have some the system will put them in the bottom unsafe area which will also be displayed

问题 In looking over the new CoreML API, I don't see any way to continue training the model after generating the .mlmodel and bundling it in your app. This makes me think that I won't be able to perform machine learning on my user's content or actions because the model must be entirely trained beforehand. Is there any way to add training data to my trained model after shipping? EDIT: I just noticed you could initialize a generated model class from a URL, so perhaps I can post new training data to

问题 I want to stop overlapping of my View with statusbar 回答1: Use Auto Layout and pin your view to Top Layout Guide, or use the new Safe Area Layout Guides. To enable it, in your storyboard's File inspector tick the following option.

问题 I've an app/project with deployment target version - iOS 10. I had used UIWebView , which is deprecated now and replaced by WKWebView . So, I want to replace UIWebView with WKWebView in my project also. It force me to either use UIWebView (with iOS 10) or change deployment target to iOS 11. I cannot change deployment target but as a middleware solution, I added code (programatically) support for both.
