弹出框的首选尺寸仅在高度大于 320 时才有效。
为了解决这个问题,我进行了很多搜索。但没有找到任何答案。 iPad 中的弹出框是否应满足最小尺寸?如果没有,我错过了什么?
代码:
UIViewController *viewController = [subStoryboard instantiateViewControllerWithIdentifier:SMFormViewControllerSBID];
controller = [[UINavigationController alloc] initWithRootViewController:viewController];
SMFormViewController *formViewController = (SMFormViewController *)controller.topViewController;
formViewController.modalPresentationStyle = UIModalPresentationPopover;
formViewController.preferredContentSize = CGSizeMake(375, 320);
popController = [controller popoverPresentationController];
popController.permittedArrowDirections = UIPopoverArrowDirectionLeft;
popController.delegate = self;
popController.sourceView = tblDocDetails;
NSInteger section = [tblDocDetails numberOfSections] - 1;
CGRect rectCustomLoc = [tblDocDetails rectForFooterInSection:section];
popController.sourceRect = CGRectMake(rectCustomLoc.origin.x, rectCustomLoc.origin.y, 130, rectCustomLoc.origin.y/2);
[self presentViewController:controller animated:YES completion:nil];
注意:
我尝试使用 adaptivePresentationStyleForPresentationController:
和 adaptivePresentationStyleForPresentationController:
返回 UIModalPresentationNone
。
最佳答案
我尝试了以下方法:
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
UIButton *btnOpen = [UIButton buttonWithType:UIButtonTypeCustom];
[btnOpen setFrame:CGRectMake(100, 100, 100, 44)];
[btnOpen setTitle:@"POP" forState:UIControlStateNormal];
[btnOpen setBackgroundColor:[UIColor grayColor]];
[btnOpen addTarget:self action:@selector(btnOpen:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btnOpen];
}
- (void)btnOpen:(id)sender {
UIView *sourceView = (UIButton *)sender;
UIViewController *vc = [[UIViewController alloc] initWithNibName:nil bundle:nil];
vc.modalPresentationStyle = UIModalPresentationPopover;
vc.preferredContentSize = CGSizeMake(150, 150);
[self presentViewController:vc animated:YES completion:nil];
UIPopoverPresentationController *popVc = vc.popoverPresentationController;
popVc.permittedArrowDirections = UIPopoverArrowDirectionLeft;
popVc.sourceView = sourceView;
popVc.sourceRect = sourceView.bounds;
}
结果是这样的(iPad Air 2,iOS 11.2):
这是基于您的示例的解决方案,我认为您使用 GCD 来显示弹出窗口可能会导致问题...
UIViewController *viewController = [subStoryboard instantiateViewControllerWithIdentifier:SMFormViewControllerSBID];
controller = [[UINavigationController alloc] initWithRootViewController:viewController];
controller.modalPresentationStyle = UIModalPresentationPopover;
controller.preferredContentSize = CGSizeMake(375, 320);
[self presentViewController:controller animated:YES completion:nil];
popController = [controller popoverPresentationController];
popController.permittedArrowDirections = UIPopoverArrowDirectionLeft;
popController.delegate = self;
popController.sourceView = tblDocDetails;
NSInteger section = [tblDocDetails numberOfSections] - 1;
CGRect rectCustomLoc = [tblDocDetails rectForFooterInSection:section];
popController.sourceRect = CGRectMake(rectCustomLoc.origin.x, rectCustomLoc.origin.y, 130, rectCustomLoc.origin.y/2);
关于ios - ViewController 内容大小不会改变弹出窗口大小,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/49110674/
