aso app store optimization

ObjectiveSome time ago, the company's small partners on the app performance optimization technology sharing. Here I tidy up a little bit and share it with you. The topic of performance optimization is very large, and the coverage can be very broad and very deep. My ability is limited, will not give you particularly difficult to understand, especially the bottom o

Especially after iOS 5.0, if your app receives memory warning, then the brain is placed on the chopping board like any other app, and is likely to be killed at any time, not to say that it will kill the app in the background first.+[nsobject Alloc]/malloc), there will be more places to use memory, su

Objective:For resource class apps, the audio/graphics occupy a large proportion of the app itself. How to store and manage these resource files has become a challenging challenge. The fragmentation of mobile, the coexistence of high school low-end mobile phones, the need for developers is not only basic storage knowledge, but also need basic optimization capabili
