objective-c - setModalTransitionStyle 和 setModalPresentationStyle，设置视图大小

Question

我创建了一个 UIViewController（一个自定义日历，其大小为 550x440），当我按下按钮时，它必须出现；问题是，如果我使用 setModalPresentationStyle 和 setModalTransitionStyle 它们会改变我的视图大小；我可以设置这些演示文稿的大小吗？

Answer 1

我找到了解决方案：

[self presentModalViewController:calendar animated:YES];

calendar.view.superview.frame = CGRectMake(0, 0, 200, 200);

Answer 2

也许您想更改设计以将日历实现为弹出框：

// Define the size of the calendar view controller for the popover
UIViewController *viewController = [[UIViewController alloc] init];
viewController.contentSizeForViewInPopover = CGSizeMake(550.0f, 440.0f);
viewController.delegate = self;

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;

// Create the popover
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:navigationController];

// Present the popover from one button
[popoverController presentPopoverFromBarButtonItem:button permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];

//release the popover content
[viewController release];
[navigationController release];
