ios – 无法在UIPopover的UINavigationController侧调整UIViewController的高度contentSizeForViewInPopover

概述我在UIPopoverController中使用UINavigationController -(void)showEditMenuFrom:(UIButton *)button{ if (self.popover) { [self.popover dismissPopoverAnimated:YES]; self.popover = nil; } 我在UIPopoverController中使用UINavigationController

-(voID)showEditMenuFrom:(UIbutton *)button{    if (self.popover) {        [self.popover dismisspopoverAnimated:YES];        self.popover = nil;    }    else {        EditMenuVIEwController *editMenuVIEwController = [[EditMenuVIEwController alloc] initWithNibname:@"EditMenuVIEwController" bundle:nil];        UINavigationController *actionsNavigationController = [[UINavigationController alloc] initWithRootVIEwController:editMenuVIEwController];        actionsNavigationController.delegate = self;        // switch for iPhone and iPad.        if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {            self.popover = [[UIPopoverController alloc] initWithContentVIEwController:actionsNavigationController];            self.popover.delegate = self;            //            CGRect presentFrame = CGRectMake(button.frame.origin.x-43,button.frame.origin.y-10,button.frame.size.wIDth,button.frame.size.height);            [self.popover presentPopoverFromrect:button.frame inVIEw:button permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];        } else {            [self presentVIEwController:actionsNavigationController animated:YES completion:^{                NSLog(@"Activity complete");            }];        }    }    }

我尝试在导航时调整UIPopover内部的视图,这些是结果：

>根视图：

2.推向其他VC

3.回到：

您可以看到根VC的高度无法更改回原点大小.

我尝试在vIEwDIDAppear,vIEwDIDLoad和UINavigationControllerDelegate中设置contentSizeforVIEwInPopover但是没有方法可以工作

-(voID)navigationController:(UINavigationController *)navigationController willShowVIEwController:(UIVIEwController *)vIEwController animated:(BOol)animated{    NSLog(@"Show VIEW %@",vIEwController);    if ([vIEwController isKindOfClass:[EditMenuVIEwController class]]) {        vIEwController.contentSizeforVIEwInPopover = CGSizeMake(160.0,160.0);    } else {        vIEwController.contentSizeforVIEwInPopover = CGSizeMake(320.0,320.0);    }}

如何解决这个问题呢？谢谢！

解决方法 我结束了我的问题,有人遇到这个解决方案：

首先,你需要在VC中声明一个在堆栈中d出的@property

@property (nonatomic,strong) UIPopoverController *popover;

然后在主代码中将其分配给UIPopoverController

self.popover = [[UIPopoverController alloc] initWithContentVIEwController:actionsNavigationController];self.popover.delegate = self;editMenuVIEwController.popover = self.popover;

最后,在要调整大小的VC的vIEwWillAppear中设置大小

-(voID)vIEwWillAppear:(BOol)animated{    [self.popover setPopoverContentSize:CGSizeMake(160,160)];    self.contentSizeforVIEwInPopover = CGSizeMake(160,160);    [super vIEwWillAppear:animated];}
