protocols

问题 My register file looks like this (Exoscape.reg): Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Classes\exoscape-launcher] "URL Protocol"="\"\"" @="\"URL:ExoScape-Launcher Protocol\"" [HKEY_CURRENT_USER\Software\Classes\exoscape-launcher\DefaultIcon] @="\"Launcher.jar,1\"" [HKEY_CURRENT_USER\Software\Classes\exoscape-launcher\shell] [HKEY_CURRENT_USER\Software\Classes\exoscape-launcher\shell\open] [HKEY_CURRENT_USER\Software\Classes\exoscape-launcher\shell\open\command] @="\

问题 I have a protocol Reusable that has a static function static func reuseId() -> String and a protocol extension that defines the default implementation for the function. Then, I implemented a extension on UITableViewCell to conform to the Reusable protocol. I can now use the function on my TableViewCells without a problem: SomeTableViewCell.reuseId() . The Problem I have is with Generics. I have a generic class that has a generic parameter of the type UITableViewCell : internal class SomeClass

问题 I tried asking a similar question recently however after several answers I realized it wasn't the correct thing to ask. Is there a guide or a generally accepted practice for generating and parsing network packets based on an existing protocol like SMPP (Short Message Peer-to-Peer Protocol [Used for SMS Messages]) or various chat protocols like HOTLINE or IRC with C#. One of the answers mentioned Google Protocol Buffers and a .NET version. After looking at that I realized that serialization is

问题 There is RMI, which I understand to be relatively fragile, direct Socket connections, which is rather low level, and Strings, which while about as solid as it gets seems to be the metaphorical PHP. What less basic options do I have for internet based Client/Server communication ? What are the advantages/disadvantages ? What are some concerns I should take into consideration ? Third party library suggestions are fine, as long as they stay platform independent (i.e. no restrictive native code).

问题 Today it is common to use //server.tld/js/script.js instead of the protocol-specific http://server.tld/js/script.js in script -Tags etc. But I want to serve a static html page without any webserver (i.e. no http://localhost:8080 ). The problem is that the browser interprets the protocol-relative link as file:///js/script.js and I can't circumvent this because it dynamically loads from a external server. In this specific case, the script is http://connect.soundcloud.com/sdk.js and loads /

问题 I have an issue (related to this SO question). But the root problem is so different than I originally thought, that I need to post it as a new question; but I'll update the previous question to reference this one - if anyone is able to help. I have a UINavigationController which has vcA as the rootViewController . vcB is then pushed onto the navigation stack. vcB has a child view which is a UIView subclass (call it BSView ) with some buttons on it. I need to have vcB be aware of when the

问题 This code does not compile and might sound stupid as it is, but i'll explain why it's so important! @objc protocol p { optional func f1() func f2() } extension p { func f1() { } func f2() { } } class foo: p { } Compiler says Type c does not conform to protocol 'p' and that's maybe because you can not use @objc optional and extensions at the same time (and does not make sence in this scenario either). But consider the following example: I want to set a selector on a non-optional method defined

问题 I have no real idea what to look for, since all I get with "Error correcting codes" is stuff related to cases where you don't know the location of the error. Thus those codes are much more complicated an inefficient than I need them to be. In the following, note that bits are equal to packets (because only a whole packet can be missing, thus the bit analogy fits very well). Are there ECCs that take into account that you already know WHICH k -bits are missing and only provide you with a way to

问题 I'm trying to build a generic UITableViewController subclass in Swift that will accommodate any number of different kinds of table view cells without having internal knowledge of any of them. To do this I'm trying to use protocols for my models and for my table view cells. The protocol for the models will return which cell class I should be going to, and the protocol for the cells will return answers to questions like what the height of the cell should be for a given model. But I'm having a

问题 I have this protocol in a objective c class: @protocol YTManagerDelegate <NSObject> @required - (void)uploadProgressPercentage:(int)percentage; @end ... and a swift class connected to it: class YTShare: UIViewController, YTManagerDelegate{ func uploadProgressPercentage(percentage:Int?){ println(percentage) } ... I receive the error: type YTShare does not conform to protocol YTShareDelegate , I have probably write incorrectly the swift function so the obj class don't find it. How I can write
