Question

在我的通用应用程序中，我试图在uialertsheet中显示webview，但得到奇怪的结果，为什么webview向左移动？和ok按钮在顶部？我想只是居中并且非常适合于uisheet窗口，但是可以点击底部的按钮

您也可以简单地忽略我的代码，并告诉我们如何实现这一目标。

UIActionSheet *msgSheet = [[[UIActionSheet alloc] 
                            initWithTitle:@"x"
                            delegate:nil 
                            cancelButtonTitle:nil  destructiveButtonTitle:nil 
                            otherButtonTitles:@"OK", nil] 
                           autorelease];
UIWebView *w=[[UIWebView alloc] init];

[w loadHTMLString:theString baseURL:nil];   
[msgSheet addSubview:w];
[w release];
[msgSheet showInView:self.view];
[msgSheet setOpaque:NO];
[msgSheet setAlpha:0.7];

CGRect wRect = msgSheet.bounds;
    w.bounds = wRect;

CGRect menuRect = msgSheet.frame;
CGFloat orgHeight = menuRect.size.height;
menuRect.origin.y -= 150; //height of webview
menuRect.size.height = orgHeight+150;
msgSheet.frame = menuRect;

CGRect wRect = w.frame;
wRect.origin.y = orgHeight;
w.frame = wRect;

    CGSize mySize = msgSheet.bounds.size;
    CGRect myRect = CGRectMake(0, 0, mySize.width, mySize.height);
    UIImageView *redView = [[[UIImageView alloc] initWithFrame:myRect] autorelease];
    [blueView setBackgroundColor:[[UIColor APP_TINT_COLOR] colorWithAlphaComponent:0.6]];       
    [msgSheet insertSubview:blueView atIndex:0];
