我今天安装了 4.2 iphone sdk 并使用 4.2 运行了我的项目(用 4.0 编写)。我注意到工具栏项目错位在工具栏上,无论是在 ipad、iphone 模拟器中。除了我还有其他人遇到过这种情况吗?这是代码:

@define TOOLBAR_HEIGHT 34
@define TOOLBAR_ITEM_WIDTH 90

// extends UIView
@implementation MapViewControllerContainer
- (void) setFrame:(CGRect)frame
{
    [super setFrame:frame];
    if (self.subviews.count == 2)
    {
        ((UIView *)[self.subviews objectAtIndex:0]).frame = CGRectMake(0, 0, frame.size.width, TOOLBAR_HEIGHT);
        ((UIView *)[self.subviews objectAtIndex:1]).frame = CGRectMake(0, TOOLBAR_HEIGHT, frame.size.width, 
                                                                       frame.size.height - TOOLBAR_HEIGHT);
    }
}
@end

// extends UIViewController
@implementation MapViewController
- (void) loadView
{
    self.view = [[MapViewControllerContainer alloc] init];
    [self.view release];

    UIToolbar * toolbar = [[UIToolbar alloc] init];
    toolbar.barStyle = UIBarStyleBlack; 

    UIBarButtonItem * flexibleItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace 
                                                                                   target:nil action:nil];
    detailsButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Details",@"") 
                                                     style:UIBarButtonItemStyleBordered target:self 
                                                    action:@selector(detailsPressed)];
    detailsButton.width = TOOLBAR_ITEM_WIDTH;
    detailsButton.enabled = NO;
    toolbar.items = [NSArray arrayWithObjects: flexibleItem, detailsButton, nil];
    [flexibleItem release];
    [detailsButton release];

    [self.view addSubview:toolbar];
    [toolbar release];

    // More non-related code here
}
@end

这是它的输出:

如您所见,详细信息按钮在右侧超出框架。TOOLBAR_​​ITEM_WIDTH 越小,它在框架内的越多。所以我认为工具栏项的计算存在一个错误,因为它在 4.0 sdk 中运行得非常好,对吧?谢谢你的帮助。
