####框架特性：
1.封装并简化了版本新特性启动视图！
2.添加了版本的本地缓存功能
3.集成简单，使用方便，没有耦合度
4.支持block回调。
####重要代码：
//判断是否需要显示：（内部已经考虑版本及本地版本缓存）
BOOL canShow = [CoreNewFeatureVC canShowNewFeature];
//测试代码，正式版本应该删除
canShow = YES;
if(canShow){
NewFeatureModel *m1 = [NewFeatureModel model:[UIImage imageNamed:@"f1"]];
NewFeatureModel *m2 = [NewFeatureModel model:[UIImage imageNamed:@"f2"]];
NewFeatureModel *m3 = [NewFeatureModel model:[UIImage imageNamed:@"f3"]];
window.rootViewController = [CoreNewFeatureVC newFeatureVCWithModels:@[m1,m2,m3] enterBlock:^{
NSLog(@"结束回调");
}];
}else{
UIViewController *vc = [[UIViewController alloc] init];
vc.view.backgroundColor = [UIColor brownColor];
window.rootViewController = vc;
}
