问题 I am trying to make a blurred background the UITabBar for my UITabViewController , and the idea is to have it be blurred and transparent so that the views underneath can be seen scrolling by. Unfortunately I cannot for the life of me get the tab bar to be transparent. No matter what I do, there is always some black background to the tab bar that prevents the underlying view controllers from showing through. If I change the alpha of the UITabBar to something low I can see that the tableview is

问题 Can you use the taptic engine in iOS 9 with iPhone 6s? WatchOS2 and OS X have the ability to use the haptic engine, so I assumed it would be in iOS 9 too, but I coudn't find any APIs for it. 回答1: Yay, I had reverse engineered internal UIKit stuff and I found another (much simpler) way to actuate feedback via TapticEngine ! We can just use AudioToolbox framework and several magic constants. import AudioToolbox AudioServicesPlaySystemSound(1519) // Actuate `Peek` feedback (weak boom)

In iOS 9 they immediately fail with a -1004 NSURLErrorDomain with the message "Could not connect to the server.". I read about Apple's change with App Transport Security and already added the entry to my Plist to disable it and allow insecure connections. I'm at a loss as to the reason for this error...any help would be great! 回答1: After messing around with a ton of different keys and

问题 Is there an api to invoke "Back to" action programmatically in order to return to the app which called (openurl) mine? 回答1: It is not possible for you to redirect back to the app The reason is The only possible way for launching another app programmatically(Exposed by Apple) is via URLScheme. That means the current app should know the URL scheme of the to-be-launched app. In your case the launched app does not not know the URL scheme of the launched app. So there is no way to go back to the

问题 I am getting the following error when trying to run my app using Xcode 7.1 Beta (7B60) with iOS 9.0 GM installed on my iPad: An error was encountered while enabling development on this device.

However, I can't even compile the library in the first place. ./configure fails, and after looking at the config.log, it seems ld is the problem as it is failing with "ld: library not found for -lSystem".
