问题 I'm just experimenting with SceneKit as a continuing migration through methods of 3D rendering. I have played with SceneKit and it is generally as advertised. One troublesome aspect (for me) is that while I can create ParticleEngines via the UI or code, I can't figure out how to set the gravitational field for particles created via code. The working code is here: https://github.com/rkwright/ParticleTest. Works with XCode 12.3 and iOS 15.3 Here is the function that sets up the ParticleEngine

问题 I'm trying to use iosMath but it shows nothing. How can I use the iosMath library to draw math labels? https://github.com/kostub/iosMath iosMath is a library for displaying beautifully rendered math equations in iOS and MacOS applications. It typesets formulae written using the LaTeX in a UILabel equivalent class. It uses the same typesetting rules as LaTeX and so the equations are rendered exactly as LaTeX would render them. I installed pod file. import UIKit import Foundation import

问题 I have to implement below scenarios with RxSwift MVVM I have two textfields (OTP & Confirm OTP) and a Submit button, If user clicks on the OTP textfield when there is no value on the OTP textfield then submit button should be disabled, Now if user types something in otp textfield button should be enabled. Now if user taps on the second text field as it is blank now then the button should be disabled again & its get enabled only when there is a value. So basically I want to enable/disable the

问题 I have tried multiple things in Azure DevOps (VSTS) to create CI for the iOS app but turns out that Azure DevOps doesn't support the apps that have App extensions. Is it really the case? I'm using the OneSignal Notification Service Extension in our project which is dependent on the main target. So, when Xcode task tries to sign the app an error occurs related to the build identifiers as the Xcode main target has a different build identifier than OneSignalNotificationServiceExtension's build

问题 This is not the regular duplicate symbols error. I am using AFNetworking library for networking with cocoa pods. I also using a third party framework that has been added to the target "Link Binary With Libraries" list in build phases section. Unfortunately, This third party framework includes the AFNetworking that apparently is being used by it for networking. Therefore, it makes sense that this error has been produced. Any idea how can this be solved? Edit: Here it shows that

问题 As I debug my app, I want to print out the value of a local variable orien of type UIInterfaceOrientation . I tried print("\(orien") but it printed: UIInterfaceOrientation ... which is obviously useless. I then tried dump(orien) , which produced another useless output: - __C.UIInterfaceOrientation In Xcode, I set a breakpoint and right-clicked the variable and chose Print Description of , which produced: Printing description of orien: (UIInterfaceOrientation) orien = <variable not available>
