在我的应用程序中，我希望在从 UIButton 调用时出现自定义弹出窗口。目前我正在使用 TSAlertView，但我想实现更多的 UI 项目并拥有更多的自定义构建。所以我想做的是在另一个视图控制器中加载一个视图控制器或视图，并能够在它们之间传递信息。请参见下面的示例：
从我读过的内容来看，据说在另一个视图控制器中加载另一个视图控制器并不是一个好习惯。在这种情况下，我认为 uiview 将是推荐的方式。这个对吗？
我希望弹出窗口后面的视图控制器具有暗淡的外观，可能是不透明度设置为 70% 的深色。我怎样才能做到这一点？
本质上，我正在尝试构建类似于具有另一个视图外观的 AlertView 的东西。
如果您打算完全阻止背景视图，您可以设置viewControllerB为Form Sheet.
当你准备好展示viewControllerB时，使用：
[viewControllerA presentViewController:viewControllerB animated:TRUE completion:nil]
您将需要一种方法来解雇viewControllerB；按钮、网络操作等
故事板的一个例子：
- (void)someMethod {
UIStoryboard *storyboard = self.storyboard;
ViewControllerB *viewCotrollerB = [storyboard instantiateViewControllerWithIdentifier:@"ViewControllerB"];
[self presentModalViewController:viewControllerB animated:YES];
}
嗨 SReca，我也有同样的要求（如上图所示）来创建像你所说的 UIalertview 的视图。
在这里，您必须创建一个新的 UIView 类而不是 UIViewController，而不需要 .xib。
在 init 方法中的新 UIView 类中，您将需要以编程方式创建用户界面。并根据需要保持其高度宽度。
而要加载这个新的 UIView，您只需创建该 uiview 的对象并调用 initwithframe，它将像 uialerview 一样以编程方式呈现该视图。
这是参考代码。
ModalPreviewViewController_iPhone.h
@interface ModalPreviewViewController_iPhone : UIView
@end
ModalPreviewViewController_iPhone.m
只需根据您在 initWithFrame 中的需要修改此示例代码
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
popUpView = [[UIView alloc] initWithFrame:CGRectMake(30,30,260,420)];
popUpBgView = [[UIView alloc] init];
popUpBgView.frame =CGRectMake(0,0,260,420);
[popUpBgView setBackgroundColor:[UIColor colorWithRed:51.0/255 green:51.0/255 blue:51.0/255 alpha:1]];
[popUpView addSubview:popUpBgView];
imageGalleryView=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 260, 360)];
[imageGalleryView setBackgroundColor:[UIColor redColor]];
CGRect btnTempFrame=CGRectMake(5, 385, 90, 30);
btnTemp=[[UIButton alloc]initWithFrame:btnTempFrame];
[btnTemp setBackgroundImage:[UIImage imageNamed:@"btn_plain_iphone.png"] forState:UIControlStateNormal];
[btnTemp.titleLabel setFont:[UIFont boldSystemFontOfSize:13]];
[btnTemp.titleLabel setTextColor:[UIColor whiteColor]];
[btnTemp addTarget:self action:@selector(onDownloadClick:) forControlEvents:UIControlEventTouchUpInside];
CGRect btnSubscribeFrame=CGRectMake(100, 385, 90, 30);
UIButton *btnSubscribe=[[UIButton alloc]initWithFrame:btnSubscribeFrame];
[btnSubscribe setBackgroundImage:[UIImage imageNamed:@"btn_plain_iphone.png"] forState:UIControlStateNormal];
[btnSubscribe.titleLabel setFont:[UIFont boldSystemFontOfSize:13]];
[btnSubscribe.titleLabel setTextColor:[UIColor whiteColor]];
[btnSubscribe setTitle:@"Subscribe" forState:UIControlStateNormal];
[btnSubscribe addTarget:self action:@selector(moveTosubscribe:) forControlEvents:UIControlEventTouchUpInside];
CGRect closeButtonFrame=CGRectMake(195, 385, 60, 30);
UIButton *closeButton=[[UIButton alloc]initWithFrame:closeButtonFrame];
[closeButton setBackgroundImage:[UIImage imageNamed:@"btn_plain_iphone.png"] forState:UIControlStateNormal];
[closeButton.titleLabel setFont:[UIFont boldSystemFontOfSize:13]];
[closeButton.titleLabel setTextColor:[UIColor whiteColor]];
[closeButton setTitle:@"Close" forState:UIControlStateNormal];
[closeButton addTarget:self action:@selector(closeView:) forControlEvents:UIControlEventTouchUpInside];
CGRect swipeLabelFrame=CGRectMake(0, 0, 140, 15);
UILabel *swipeLabel=[[UILabel alloc]initWithFrame:swipeLabelFrame];
[swipeLabel setBackgroundColor:[UIColor clearColor]];
[swipeLabel setText:@"> SWIPE TO SEE MORE"];
[swipeLabel setTextColor:[UIColor lightGrayColor]];
[swipeLabel setFont:[UIFont systemFontOfSize:12]];
CGRect dateLabelFrame=CGRectMake(5, 365, 100, 15);
dateLabel=[[UILabel alloc]initWithFrame:dateLabelFrame];
[dateLabel setBackgroundColor:[UIColor clearColor]];
[dateLabel setText:@"July 2013 #93"];
[dateLabel setTextColor:[UIColor whiteColor]];
[dateLabel setFont:[UIFont systemFontOfSize:13]];
CGRect priceLabelFrame=CGRectMake(155, 365, 100, 15);
priceLabel=[[UILabel alloc]initWithFrame:priceLabelFrame];
[priceLabel setBackgroundColor:[UIColor clearColor]];
[priceLabel setText:@"$3.9"];
[priceLabel setTextColor:[UIColor colorWithRed:71.0/255 green:191.0/255 blue:226.0/255 alpha:1]];
[priceLabel setFont:[UIFont systemFontOfSize:13]];
[priceLabel setTextAlignment:NSTextAlignmentRight];
CGRect labelFrame=swipeLabel.frame;
labelFrame.origin=CGPointMake(popUpView.frame.origin.x+popUpView.frame.size.width - labelFrame.size.width, popUpView.frame.origin.y - labelFrame.size.height);
[swipeLabel setFrame:labelFrame];
[popUpView addSubview:imageGalleryView];
[popUpView addSubview:btnTemp];
[popUpView addSubview:closeButton];
[popUpView addSubview:btnSubscribe];
[popUpView addSubview:dateLabel];
[popUpView addSubview:priceLabel];
[UIView beginAnimations:@"curlup" context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:.5];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:popUpView cache:YES];
[self addSubview:popUpView];
[self addSubview:swipeLabel];
[UIView commitAnimations];
UIColor *color = [[UIColor alloc] initWithRed:0.0 green:0.0 blue:0.0 alpha:0.5];
self.backgroundColor = color;
[[[UIApplication sharedApplication] keyWindow] addSubview:self];
[self initializeVariables];
}
return self;
}
在父视图控制器中，只需创建 UIView 类的对象并使用您想要的 initWithFrame 和大小调用它
ModalPreviewViewController_iPhone *mpvc=[ModalPreviewViewController_iPhone alloc];
if(appDelegate.isIphone5)
mpvc=[mpvc initWithFrame:CGRectMake(0,0,320,480)];
else
mpvc=[mpvc initWithFrame:CGRectMake(0,0,320,568)];
并解雇 UivewClass
只需在其（UIviewClass's）方法之一（如closeView）中编写以下句子即可将其关闭
[self removeFromSuperview];
