1.弹出控制器
GOVAlertViewController *alertVC = [[GOVAlertViewController alloc] init];
alertVC.modalPresentationStyle = UIModalPresentationOverFullScreen;
[self presentViewController:alertVC animated:NO completion:nil ];
因为父视图的透明度会影响到子视图,所以想要在GOVAlertViewController上添加各种view的话,先给GOVAlertViewController添加一个全屏的半透明背景view ; 或者简单的给父视图背景色[UIColor colorWithRed:0 green:0 blue:0 alpha:0.6];里设置透明度
- (id)init{
if (self == [super init]) {
self.view.backgroundColor = [UIColor clearColor];
UIView *bgView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
bgView.backgroundColor = [UIColor blackColor];
bgView.alpha = 0.6;
[self.view addSubview:bgView];
UIImageView *alertView = [[UIImageView alloc] initWithFrame:CGRectMake((self.view.frame.size.width - 300)/ 2.0, (self.view.frame.size.height - 500)/ 2.0, 300, 500)];
alertView.alpha = 1;
alertView.image = [UIImage imageNamed:@"alert.jpeg"];
alertView.contentMode = UIViewContentModeScaleAspectFit;
[self.view addSubview:alertView];
}
return self;
}
