I wish this helpful for you You can recover your non-frosted appearance by making your window borderless.
@interface BorderlessWindow : NSWindow


@implementation BorderlessWindow

- (instancetype)initWithContentRect:(NSRect)contentRect styleMask:(NSWindowStyleMask)style backing:(NSBackingStoreType)backingStoreType defer:(BOOL)flag {

    self = [super initWithContentRect:contentRect

    return self;

@implementation DummyAlertWindowController

- (void)windowDidLoad {
    [super windowDidLoad];
    [self.window setOpaque:NO];
    [self.window setHasShadow:NO];
    [self.window setBackgroundColor:[NSColor clearColor]];

Reload UIWebView from a popover view being displayed modally

Hope that helps Unless I misunderstood your question, this seems fairly easy to accoumplish. I suppose you could sent a notification from UIPopoverController. First in your main view controller in viewWillAppear add self as observer:
     [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(reloadMyWebView:) name:@"reloadWebView" object:nil];
    - (void)realoadMyWebView:(NSNotification *)notification
   [[NSNotificationCenter defaultCenter]removeObserver:self];
   [[NSNotificationCenter defaultCenter]postNotificationName:@"reloadWebView" object:nil userInfo:nil];

UIViewController displayed behind current view when presented modally

this one helps. I have finally found the issue. For some awkward reasons, the rootViewController of the root window wasn't set properly, leading to strange behaviors with modal views.
What is the more puzzling is that it worked fine on iOS 4 so far and failed on iOS 5. I believe I'm still missing the true reasons leading to such trouble, but correctly setting the rootViewController in AppDelegate solved the problem.
