我正在为iPad开发一款应用。在一个功能中,我想显示 FullCustom Popover

为此我的代码如下: -

DuplicateViewController *viewControllerForPopover =
    [self.storyboard instantiateViewControllerWithIdentifier:@"DuplicatePopoverVC"];
    viewControllerForPopover.arr_studentDetail = self.arrStudentDetail;
    viewControllerForPopover.dictSelectedProg = dictSelectedProgram;

    self.popover = [[UIPopoverController alloc]
                    initWithContentViewController:viewControllerForPopover];
    [self.popover setPopoverContentSize:CGSizeMake(self.view.frame.size.width, self.view.frame.size.height)];

    viewControllerForPopover.modalPresentationStyle = UIModalPresentationFullScreen;
    [self.popover setBackgroundColor:[[UIColor darkGrayColor] colorWithAlphaComponent:0.4]];
    [self.popover presentPopoverFromRect:self.view.bounds inView:self.view permittedArrowDirections:0 animated:YES];

我设置了popover大小并尝试了其他选项,但无法全屏显示。

ViewDidLoad - > DuplicateViewController

[view_main.layer setBorderWidth:5.0f];
[view_main.layer setCornerRadius:25.0f];
[view_main.layer setBorderColor:[UIColor colorWithRed:(29.0f/255.0f) green:134.0f/255.0f blue:140.0f/255.0f alpha:1.0f].CGColor];

但是在运行App时,它显示如下: -

请帮我显示全屏Popover。非常感谢你。

答案 0 :(得分:1)

创建两个类 第一个应该继承UIPopoverController 第二个应该继承UIPopoverBackgroundView

例如:

<强> CustomUIPopoverController.h

@interface CustomUIPopoverController : UIPopoverController

<强> CustomUIPopoverController.m

@implementation CustomUIPopoverController

- (id)initWithContentViewController:(UIViewController *)viewController {
    self = [super initWithContentViewController:viewController];
    if (self) {
        self.popoverBackgroundViewClass = [CustomUIClearPopoverBackgroundView class];
        [self setPopoverContentSize:viewController.view.frame.size];
    }
    return self;
}

@end

<强> CustomUIClearPopoverBackgroundView.h

@interface CustomUIClearPopoverBackgroundView : UIPopoverBackgroundView

<强> CustomUIClearPopoverBackgroundView.m

#import "CustomUIClearPopoverBackgroundView.h"

@implementation CustomUIClearPopoverBackgroundView

#pragma mark - no arrow

+ (CGFloat)arrowHeight {
    return 0;
}

+ (CGFloat)arrowBase {
    return 0;
}

- (CGFloat)arrowOffset {
    return 0;
}

- (void)setArrowOffset:(CGFloat)arrowOffset {

}

- (UIPopoverArrowDirection)arrowDirection {
    return 0;
}

- (void)setArrowDirection:(UIPopoverArrowDirection)arrowDirection {
}


#pragma mark - no margins

+ (UIEdgeInsets)contentViewInsets {
    return UIEdgeInsetsZero;
}

#pragma mark - fully transparent (default is 0.15)

+(BOOL)wantsDefaultContentAppearance {

    return NO;
}

- (void)willMoveToWindow:(UIWindow *)newWindow {
    [super willMoveToWindow:newWindow];

    // hide shadow image view
    [self.superview.subviews[0] setHidden:YES];
}
@end

我用过这个,但我不太喜欢它。 第二个选项是创建容器视图并隐藏/显示它。 这样它就是一个纯粹的视图控制器,你不需要搞乱弹出的东西 要创建透明度,使容器视图background = clear,视图控制器视图背景颜色=清除,并为视图控制器的大小添加半透明黑色背景的半透明按钮。单击按钮关闭窗口(=与弹出背景相同的效果)
