Version judgment:

1. First you need to know this key value pair of Key:id key = (id) kcfbundleversionkey;

2. Get the current version number with the local nsbundle.

3. Obtain the corresponding version number in the sandbox.

4. Compare to determine the loading situation.

    //get the current version first, get it from plist//find the current corresponding version in the bundle    IDKey = (ID) Kcfbundleversionkey; Nsdictionary*infodictionary=[NSBundle mainbundle].infodictionary; NSString*currentversion =[Infodictionary Objectforkey:key]; //bundles obtained from the sandboxNsuserdefaults *defaults=[Nsuserdefaults Standarduserdefaults]; NSString*defaultversion =[Defaults Objectforkey:key]; if([defaultversion isequal:currentversion]) {Self.window.rootViewController=[[Csmainbarcontroller alloc]init]; }Else{Cslaunchview*indexview =[[Cslaunchview alloc]init]; Self.window.rootViewController=Indexview; }

1. Create a new class to load the corresponding picture. The Uiscrollview is then set on a view through the Uivivecontroller.

2. Load the corresponding view

3. Load the corresponding Pagecontroller
