独立UINavigationBar？ [英] Standalone UINavigationBar?

问题描述

我想要创建一个带有几个按钮在iPhone界面的状态栏下面的几个按钮，控制器是一个简单的UIViewController，因此这是一个用于按钮不用于导航的酒吧。我有工作，但感觉有点笨重，我想知道我是否正确，没有缺少任何快捷方式。

• 我可能会删除NSArray方便的方法并添加一个alloc / release。

代码：

   - （void）loadView {
 // VIEW 
 UIView * tempView = [[UIView alloc] initWithFrame：screenFrame]; 
 
 // NAV BAR 
 UINavigationBar * tempNavigationBar = [[UINavigationBar alloc] initWithFrame：CGRectMake（0，0，320，44）]; 
 [tempNavigationBar setBarStyle：UIBarStyleBlack]; 
 UIBarButtonItem * testButton = [[UIBarButtonItem alloc] initWithTitle：@TESTstyle：UIBarButtonItemStyleBordered target：self action：nil]; 
 
 UINavigationItem * navItem = [[UINavigationItem alloc] init]; 
 [navItem setLeftBarButtonItem：testButton]; 
 [testButton release]; 
 
 [tempNavigationBar setItems：[NSArray arrayWithObject：navItem]]; 
 [tempView addSubview：tempNavigationBar]; 
 [tempNavigationBar release]; 
 [navItem release]; 
 
 [self setView：tempView]; 
 [tempView release]; 
} 
  

解决方案

一个替代方法是在Interface Builder中执行此操作，但这是一个完全不同的事情。

如果您打算支持自动旋转，您可能需要添加一些代码自动调整导航栏的掩码，使其正确扩展。实际上，我会使用Interface Builder来实现这一点，因为我很想看到我的自动调整大小的掩码。

I am looking to create a bar with a couple of buttons at the top of the iPhone interface just under the statusBar, the controller is a simple UIViewController so this is a bar for buttons not for navigation. I have got things working but it feels a little clunky and I was wondering if I was doing it right and not missing any shortcuts.

• There is no action / selector: set yet as I am just setting this up.
• I will probably remove the NSArray convenience method and add an alloc/release.

Code:

- (void)loadView {
    // VIEW
    UIView *tempView = [[UIView alloc] initWithFrame:screenFrame];

    // NAV BAR
    UINavigationBar *tempNavigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    [tempNavigationBar setBarStyle:UIBarStyleBlack];
    UIBarButtonItem *testButton = [[UIBarButtonItem alloc] initWithTitle:@"TEST" style:UIBarButtonItemStyleBordered target:self action:nil];

    UINavigationItem *navItem = [[UINavigationItem alloc] init];
    [navItem setLeftBarButtonItem:testButton];
    [testButton release];

    [tempNavigationBar setItems:[NSArray arrayWithObject:navItem]];
    [tempView addSubview:tempNavigationBar];
    [tempNavigationBar release];
    [navItem release];

    [self setView:tempView];
    [tempView release];
}

解决方案

That looks alright to me. An alternative would be to do this in Interface Builder, but that's a completely different matter.

If you intend to support autorotation, you may have to add some more code to set autoresize masks for your navigation bar so it expands correctly. Actually, I would use Interface Builder for this, because I'm big on visualizing my autoresize masks.
