问题 I am trying to ask for location permission on iOS 11 with React Native. There is a change from Apple coming with iOS 11 where we have a third option for using the location permission only when using the app. Our app is location based and need the user's coordinates even when the app is in the background so I would like the user to have the option to click 'Always' the first time the popup shows up. The problem is that the only popup which shows up is not having the three options (the first

问题 Thanks to this great article(http://machinethink.net/blog/coreml-custom-layers/), I understood how to write converting using coremltools and Lambda with Keras custom layer. But, I cannot understand on the situation, function with two parameters. #python def scaling(x, scale): return x * scale Keras layer is here. #python up = conv2d_bn(mixed, K.int_shape(x)[channel_axis], 1, activation=None, use_bias=True, name=name_fmt('Conv2d_1x1')) x = Lambda(scaling, # HERE !! output_shape=K.int_shape(up)

问题 Like many apps, my iOS app offers the user a chance to open the app's settings page if a certain privacy permission has been disabled. In iOS, using the special UIApplicationOpenSettingsURLString / openSettingsURLString URL takes the user to the app specific page of the Settings app. There the user sees various privacy settings used by the app in addition to any settings setup in the Settings.bundle provided by the app (if any). While working on the Mac Catalyst port of the iOS app, this is

问题 I integrated the Push Notification to the CloudKit so that every change in the iCloud will pop up a notification on my iPhone and the badge app icon number will add one correspondingly. However, when I used the code: application.applicationIconBadgeNumber = 0 to reset that number in the applicationDidBecomeActive(_ application: UIApplication) , I noticed that the badge app icon number truly disappeared but if another new notification came again, the number won't start from one again as

问题 Below is example code of MessageKit library. Currently, its behavior is that all image messages must be loaded completely before displaying to end user so it takes a lot of time to wait.

问题 There are many answers to get cursor CGPoint within UITextView. But I need to find a position of cursor in relation to self.view (or phone screen borders). Is there a way to do so in Objective-C? 回答1: UIView has a convert(_:to:) method that does exactly that. It converts coordinates from the receiver coordinate space to another view coordinate space. Here is an example: Objective-C UITextView *textView = [[UITextView alloc] initWithFrame:CGRectZero]; UITextRange *selectedTextRange = textView

问题 I have problems when some hardware issues appears and my kivy app crashes. For example on Android or iOS. Regular users can't see the log, neither can I. So, when my application starts, I want to create separate process and somehow look at the status of main application. In case of it's crash I'd like to send error log to my server. So, what is the best way to do this? Maybe another process is redundant and I can make it in more simple way? And how exactly I can catch crash log?...Thanks! 回答1

问题 Can I transfer audio stream from one iOS device to other iOS device (for example from 4s to new iPad) using CoreBluetooth framework. Maybe BLE is too slow fo media streaming? 回答1: Bluetooth Low Energy (BLE) is not intended to stream data ! If you want to a stream you MUST use Bluetooth 2.X+EDR and an appropriate profile. Therefore, if you want to stream audio, you need a headset or A2DP profile. CoreBluetooth API give only access to BLE devices. 回答2: Audio streaming wont work any good, since
