如何在导航控制器栏上覆盖视图？
我有点小问题。我正在尝试向我的应用程序添加一个 popoverview，但 popoverview 的一部分被我的导航控制器栏隐藏了。如何使我的 popoverview 覆盖在导航控制器栏的顶部？这是问题的图片： http://img593.imageshack.us/img593/4056/viewn.jpg
这是我正在使用的代码：
- (IBAction)onButtonClick:(UIButton *)button {
if (self.popoverController) {
[self.popoverController dismissPopoverAnimated:YES];
self.popoverController = nil;
[button setTitle:@"Show Popover" forState:UIControlStateNormal];
} else {
UIViewController *contentViewController = [[WEPopoverContentViewController alloc] initWithStyle:UITableViewStylePlain];
self.popoverController = [[[WEPopoverController alloc] initWithContentViewController:contentViewController] autorelease];
[self.popoverController presentPopoverFromRect:button.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionDown
animated:YES];
[contentViewController release];
[button setTitle:@"Hide Popover" forState:UIControlStateNormal];
}
}
是否有办法使此弹出窗口位于导航控制器栏上方？
希望有人知道如何解决这个问题，提前致谢。
I've sorta got a little problem. I'm trying to add a popoverview to my app but part of the popoverview get's hidden by my navigation controller bar. How can I make my popoverview overlay over top of the navcontrollerbar? Here's an image of the problem: http://img593.imageshack.us/img593/4056/viewn.jpg
Here's my code I'm working with:
- (IBAction)onButtonClick:(UIButton *)button {
if (self.popoverController) {
[self.popoverController dismissPopoverAnimated:YES];
self.popoverController = nil;
[button setTitle:@"Show Popover" forState:UIControlStateNormal];
} else {
UIViewController *contentViewController = [[WEPopoverContentViewController alloc] initWithStyle:UITableViewStylePlain];
self.popoverController = [[[WEPopoverController alloc] initWithContentViewController:contentViewController] autorelease];
[self.popoverController presentPopoverFromRect:button.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionDown
animated:YES];
[contentViewController release];
[button setTitle:@"Hide Popover" forState:UIControlStateNormal];
}
}
Is there anyway to make this popover above the navigation controller bar?
Hopefully someone knows how to fix this problem, Thanks in advance.

这可能与
WEPopoverController PresentPopoverFromRect:inView:permissedArrowDirections:animated:的 inView 参数有关吗？您是否可以在视图层次结构中进一步呈现（例如在 self.view.window 中），而不是在 self.view 中呈现它？Could this be related to the inView parameter to
WEPopoverController presentPopoverFromRect:inView:permittedArrowDirections:animated:? Instead of presenting it inself.viewcould you present further up in the view hierarchy (like inself.view.window)?哦..我明白了..我改变了
WEPopOverController 中 函数的行
来自
[keyView addSubview:backgroundView];到
[theView addSubview:backgroundView];ohh..I got it..I changed line in function
in WEPopOverController
from
[keyView addSubview:backgroundView];to
[theView addSubview:backgroundView];
