Swift use 'is' for function type, compiler behavior is different with runtime

由 大憨熊 提交于 2019-12-23 04:45:10
问题 I am testing about function is first class citizen in Swift. and I got in trouble. Check the code below: let f: Int -> Int = { $0 } if f is (Int -> Int?) { // compiler warning: 'is' test is always true print("hello") } else { print("ops") // runtime: this line is executed } I got a compiler warning in the if line says: "'is' test is always true". But when I run the code, console print "ops" which means is test is false. This confuses me. Why compiler says true when runtime says false? 来源：

Silverlight 3 Dataform - how to add fieds at runtime

由 故事扮演 提交于 2019-12-23 04:30:35
问题 I am creating a DataForm from dynamic data (so I can't create the columns in the xaml), I currently create columns for my DataGrid (I have not worked out how I can create a button + event in a colomn yet) foreach (var item in headings.Entities) { theDataGrid.Columns.Add( new DataGridTextColumn { Header = item.Label, Binding = new Binding(item.LocalName) }); } I cannot see any methods to add fields to a DataForm at runtime, however... 回答1: You'd be better off not creating your datagrid columns

How to get all Color methods of UIColor?

由 戏子无情 提交于 2019-12-23 04:26:28
问题 UIColor has color methods such as blackColor , whiteColor and so on. I would like to get a color list of them like: ['blackColor','whiteColor'...] . But after checking the method_list , ivar_list and property_list , I find no color method in the lists. The code is written in Swift as following: //: Playground - noun: a place where people can play import UIKit var ivarCount: UInt32 = 0 var propertyCount: UInt32 = 0 var methodCount: UInt32 = 0 let ivars = class_copyIvarList(UIColor.self,

Can Byte Buddy create fields and method annotations at runtime?

由 房东的猫 提交于 2019-12-23 03:51:37
问题 I would like to implement this 3rd-party annotation to map my class's fields/properties to my database table columns. I can easily implement the annotations at compile time (as shown in the example code below) but I can't find a way to do this at runtime. (I am loading the library at runtime using reflection.) My question is how can I implement the same mapping annotation when loading a library at run time? Can Byte Buddy handle this for Android? //3rd party annotation code package weborb

BaseTransientBottomBar and related bug, and how to resolve it

由 ▼魔方 西西 提交于 2019-12-23 02:53:36
问题 Firstly, What I tried to resolve the issue below: Step 1. I have put a method in my BaseActivity and BaseActivity abstract class, to know when the Activity is stopped and when view (root view of fragment) is destroyed [returns true in both the cases, but false before the event (onStop(), onViewDestroyed()) is called]. Step 2. I have prevented the one and only SnackBar to be shown when the true is returned in any of the both. Also checked isFinishing() of the BaseActivity. But the error does

Android: The right way to debug an running application (runtime errors/log)

由 筅森魡賤 提交于 2019-12-23 01:57:24
问题 I am new to Android development. I have been going through the tutorials. I would like to know which is the right way to debug / log an application during its execution. I am guessing I should be able to execute my application directly on my android device and be able to view a log or so to catch runtime errors and logs? How could I accomplish this ? I am using this to install the application on my phone adb install <path to apk> p.s. I am sure this question might seem like something I should

ObjC Runtime 黑魔法 — Method Swizzling

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 适用情境 项目中大量控制器需要在载入时进行日志统计或进行类似的处理。如果直接往所有控制器中进行代码编写，会产生大量的重复的代码，降低了代码后期的可读性，不利于维护。由于所有部分的逻辑代码相同，针对这种情况，以切面编程（AOP）思想为导向，利用 Method Swizzling 能极大降低这种（日志统计）非主要逻辑代码与控制器的耦合度。 AOP概念详解（摘自百度百科） 在软件业，AOP为Aspect Oriented Programming的缩写，意为：面向切面编程，通过预编译方式和运行期动态代理实现程序功能的统一维护的一种技术。AOP是OOP的延续，是软件开发中的一个热点，也是Spring框架中的一个重要内容，是函数式编程的一种衍生范型。利用AOP可以对业务逻辑的各个部分进行隔离，从而使得业务逻辑各部分之间的耦合度降低，提高程序的可重用性，同时提高了开发的效率。 通过Demo来学习(MethodSwizzling_Demo) 1. 创建一个空工程，再为工程中的 ViewController类创建一个分类（Logging）。 2. 在ViewController 中重载 viewDidAppear: 方法。 - (void)viewDidAppear:(BOOL)animated { [super
