one of the SEO skills Note: When we write routing rules, because the routing rules are sequential (in the order in which they are registered), the routing rules that are written may be captured and processed by the rules in front of it. The route that is registered later is invalid 2, Controller learning In asp.net mvc, a controller can contain multiple action. Each action is a method that returns a Actio

All development environments for this study are VS2012+MVC4 one: what is MVC:Let's say you're learning MVC for the first time, okay? We don't understand how it's going to function inside, we just start with the letter meaning of its surface. M:models (model) V:view (view) c:controllers (Controller) Don't dwell on what these three letters are, and what is the use of these three things! All we have to do is w

In short, their mode of work is like this.Summarize:C to M:apiC to V:outletV to C:target-action, Delegate,datasourceM to C:notification,kvoOriginal source: http://blog.
