###IOS9前版本

- (void)applicationWillResignActive:(UIApplication *)application {

// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.

// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.

//1.从Info.plist取出版本号

NSString* version = [NSBundle mainBundle].infoDictionary[key];

//2.从沙盒中取出上次存储的版本号

NSString* saveVersion = [[NSUserDefaults standardUserDefaults] objectForKey:key];

if([version isEqualToString:saveVersion])

}else{  //将新版本写入沙盒
