问题 My Code: EKEventStore* eventStore = [[EKEventStore alloc] init]; [eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError * _Nullable error) { }]; The app's Info.plist already contain an NSRemindersUsageDescription key and NSCalendarsUsageDescription key, but the code below works fine on iOS 8 and 9, but on iOS 10 it crashes .like: [access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's

问题 I think I'm missing something simple, but I can't find any examples showing how to do this... also, please forgive me if some of the terminology I'm using is wrong. I simply want to use an HTML form that is bound to a Kendo Observable object to create a new record in my remote datasource. All the examples I've seen show how to edit existing records, but that's not what I'm looking for (at least not at the moment). I've created a Fiddle http://jsfiddle.net/matbeard/fYfYz/2/ with a simple cut

问题 I'm trying to style my renderItem in FlatList but elevation not working properly. Is there anything I'm wrong or this is a React Native issue? I tested ListView too but it still not working properly This is TodoItem component import React, { Component } from 'react' import { Text, View, StyleSheet } from 'react-native' const styles = StyleSheet.create({ container: { height: 60, backgroundColor: 'white', borderRadius: 10, shadowColor: '#000', shadowOffset: { width: 2, height: 2 },

问题 I am trying to cast a list of objects within a consturctor for a derive class IntersectionPath as follows. public class IntersectionPath : Path<IntersectionSegment>, IEnumerable { //Constructors public IntersectionPath() : base() { Verts = null; } public IntersectionPath(List<Intersection> inVerts, List<Segment<Node>> inEdges) : base() { this.Segments = (List<IntersectionSegment>) inEdges; } } Segments is defined in the generic base class Path public class Path<T> : IEnumerable<T> where T :

问题 I'm wondering can I get the result when it cause timeout Exception when use Future and ExecutorService, for example, below is my code package com.example; import java.util.UUID; import java.util.concurrent.ExecutorService; import java.util.concurrent.Future; import java.util.concurrent.LinkedBlockingQueue; import java.util.concurrent.ThreadPoolExecutor; import java.util.concurrent.TimeUnit; import java.util.concurrent.TimeoutException; import org.apache.commons.lang3.concurrent

问题 I need some help building a linux bash script to find and delete oldest file with special characters and white spaces in a directory tree if condtion is met. I have been searching the forum for questions like this and thanks to users here I came with output as seen under. So far I can't figure out how to pipe the output filename to rm, so that it is being deleted. The goal is to check if hdd is running full, and if so delete the oldest file until free-space requirement is met. The problem is,

问题 We have some files encoded in AV1, but we recently noticed that Chrome mobile fails to play the files - but it doesn't fall back to an encoding it can use - it just puts the unplayable AV1 file in there. I'm hoping that if we add a codec attribute we can remedy this - but I'm not sure how to determine the codec for these AV1 files. I've come across this documentation on MDN, but I'm not sure how I would determine the proper codec from that. It starts off simple enough, but some of the values

问题 I am brand new to PyTorch and want to do what I assume is a very simple thing but am having a lot of difficulty. I have the function sin(x) * cos(x) + x^2 and I want to get the derivative of that function at any point. If I do this with one point it works perfectly as x = torch.autograd.Variable(torch.Tensor([4]),requires_grad=True) y = torch.sin(x)*torch.cos(x)+torch.pow(x,2) y.backward() print(x.grad) # outputs tensor([7.8545]) However, I want to be able to pass in a vector as x and for it

问题 I'm struggling with memory management or correct usage of object oriented Fortran 2008. My code has multiple derived types with the same parent (here Example01 and Example02 ) stored in a Example_Class module. I want to load one example in a subroutine workenv depending on some variable (here idx_example ). Whichever one is chosen should be accessed by procedures defined in the base class, so I can do call active_Example%Info() regardless of what active_Example is. The following code compiled
