Data is passed between view in two main categories: direct and indirect delivery. In which indirect delivery can also define a singleton that is used to share data."Old solution before IOS5"1) Using the proxy mode sub-Viewcontroller Design Agent protocol, define the Protocol interface, the parent Viewcontroller implement the Protocol interface, the implementation of the child Viewcontroller exit when the relevant data updated to the parent view.2) using the message mechanism of

For iOS apps, it's important to know if your application is running in the foreground or in the background.

Jump between IOS apps Let's discuss how to enable app2 from app1 in iOS development. The basic idea is that you can define a URL for app2. In app1, you can open app2 by opening this URL. In this process, you can transmit some parameters. The following describes the specific implementation process. 1. the URL defined in info. plist of app2 is to add the URL types

intercept the URL of the original application, To return, relatively simple;Method 2> through the way of event delivery, by setting a urL string property in the host controller, in the method of opening the application, the URL that is passed in to the homepage controller is assigned to the URL of the master, and the URL is passed to the jump interface in the home controller. Then in the corresponding interface through a singleton attribute to get URL string intercept the URL of the original ap
