popoverviewController在iPhone上崩溃，适用于iPad [英] popoverviewController crash on iPhone, works on iPad

问题描述

这里有一个菜鸟问题：

为什么这段代码有任何想法：

any ideas why this code:

UIViewController* popoverviewController = [[UIViewController alloc]init];
UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];

[webViewnetwork loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"webView" ofType:@"html"]isDirectory:NO]]];
[popoverView addSubview:webViewnetwork];

popoverviewController.view = popoverView;
popoverviewController.contentSizeForViewInPopover = CGSizeMake (100, 100);

self.popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverviewController];
[self.popoverController presentPopoverFromRect:CGRectMake(0, 0, 1, 1) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

在iPad上运行正常，但在iPhone上崩溃了吗？
我正在尝试做与我的iPad版本相同的事情，即添加带有html格式文本的子视图。它在第7行崩溃（程序接收信号：SIGABRT）（initWithContentViewController）

would work fine on iPad, but crash on iPhone ? I'm trying to do the same thing as in my iPad version, which is adding a subview with an html formatted text. It crashes (program received signal: SIGABRT) on the 7th line (initWithContentViewController)

谢谢！

推荐答案

因为 UIPopoverController 仅适用于iPad。
