Multiple languages typically have two approaches in an application:One, the procedure provides to the user oneself choice opportunity;Second, according to the current user mobile device language automatically switch our app to the corresponding language.

there is a response, simplifying the complexity of the code. This is more common in node.js, but it is also more expressive of the misuse of asynchronous event programming. New people use Node.js will always find that basically anything is asynchronous, the database is asynchronous, IO file operation is asynchronous, session read and write is asynchronous, even get the request object are asynchronous. This leads many people to be nesting callback functions, leading to the famous callback Hell

Delegate is a very common design pattern in iOS systems and is used in many places. Before the beginning of contact with OC, for this delegate mode is very not understand, do not know what this so-called delegate is used for. However, after a few years of development of iOS, for this piece also has its own understanding. First, the definition of delegate is an object that inherits a particular interface.

Fiddler not only intercepts HTTP requests from various browsers, but also intercepts HTTP/HTTPS requests made by various smartphones. Fiddler can capture requests from iOS devices, such as the iphone, IPad, and MacBook. Wait for the Apple device. Similarly, can also intercept andriod,windows phone and other equipment issued by the HTTP/HTTPS. Most crucially, when you grab the iOS app, you do it directly on
