iOS 半透明控制器

方式一:(建立簡單,可控制性小)

    MyController *myVC = [[MyController alloc] init];    myVC.modalPresentationStyle = UIModalPresentationOverFullScreen;//    UIView *image =  [[UIApplication sharedApplication].keyWindow snapshotViewAfterScreenUpdates:YES];//    image.backgroundColor=[UIColor blackColor];//    image.alpha = 0.0;//    [myVC.view insertSubview:image atIndex:0];    [self presentViewController:myVC animated:NO completion:^{//        image.alpha = 0.1;    }];

子控制器寫上:

- (void)viewDidAppear:(BOOL)animated{    [super viewDidAppear:animated];    self.view.alpha = 0.98;

方式二:
就是popover方式的:demo在碼雲上面,不貼連結。
