Does Objective-C have something like C++ virtual functions?

由 守給你的承諾、 提交于 2019-12-08 09:06:39
问题 In objective-c it is possible to add a @dynamic to a property. Is this also possible for normal instance methods? EDIT I think i wasn't clear enough. I want to do the following: @interface MyClass @property (retain) NSObject *somePropertyObject; - (void) myMethod; @end @implementation MyClass @dynamic somePropertyObject; //Make myMethod dynamic. I do not want to implement it. Like C++ Virtual @end 回答1: I think you might be asking how to declare a method that will be implemented some time

How to implement UITableView With Static and Dynamic Cells — IOS

由 ♀尐吖头ヾ 提交于 2019-12-08 08:48:32
问题 I've created a UITableView that is entirely composed of four different groupings. Each section/group has a different number of rows. I've statically added the necessary number of rows and textfields for the bottom three groups. However, I do not know how many rows I will need for the top section/group. I've set up the top group as just having one cell in the .xib, but each time the view loads I am going to have to check how many cells I need and then dynamically add the necessary number of

由 烂漫一生 提交于 2019-12-08 08:32:22
问题 The problem I am facing is with the tree model of the JTree.

JSON to Dynamic Object vs. Strongly Typed Object

由 我与影子孤独终老i 提交于 2019-12-08 08:14:36
问题 I'm not sure if I don't get the big picture or if I just miss something but what are the benefits of parsing a JSON-String to a dynamic object? If I have a class like this class Product { public string Name { get; set; } public double Price { get; set; } public string Category { get; set; } } and I use the HttpClient to get the object like this Product product = await response.Content.ReadAsAsync<Product>(); What do I benefit from this code? string content = await response.Content

R Shiny: Isolate dynamic output within dynamic tabs

由 ≯℡__Kan透↙ 提交于 2019-12-08 07:56:59
问题 I am trying to create an app where you choose certain inputs in the sidebar, and when you click on a button it will show the results in a separate tab. I created a tiny example that you can use below. In this example, you choose 4 letters in the sidebar and if you click on the button, it dynamically creates a separate tab with text output. However, when you change the letters and click on the button again, all previous tabs will update with the new results. I'd like to isolate the result in

C# Dynamic Linq Query with Fluent Mongo - Without using Contains or PredicateBuilder

由 删除回忆录丶 提交于 2019-12-08 07:52:56
问题 I'm using Fluent Mongo and having issues creating a dynamic linq query because Fluent Mongo doesn't support Contains. I basically need to have a nested OR statement within my Where to check if an Enum matches a list of enums. I'm sure there's another way to do this without using Contains, I just don't know enought about linq...
