<!-- p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 13.0px 'Lucida Grande'} span.s1 {font: 13.0px 'Heiti SC Light'} -->

as is: 原样.

xcode4snapshot快照功能:

File->create snapshot.

restore:Window > Organizer->project.

wantsFullScreenLayout
@property(nonatomic,assign) BOOL wantsFullScreenLayout
self.navigationController.wantsFullScreenLayout = YES;
statusBarStyle
@property(nonatomic) UIStatusBarStyle statusBarStyle;
application.statusBarStyle = UIStatusBarStyleBlackTranslucent;

打印所有window的子视图

递归函数:

 [self performSelector: @selector(printWindowSubViews) withObject: nil afterDelay: 2.0];
-(void) printWindowSubViews
{
    printSubViews(self.window, 0);
}
// 递归
void printSubViews(UIView *parentView, int indent)
{
    for(int i = 0; i < indent; i++)
    {
        printf("-");
    }
    
    printf("[%2d] %s, frame = %s\n", indent, 
           [[[parentView class] description] UTF8String], 
           [NSStringFromCGRect(parentView.frame) UTF8String]);
    
    for(UIView *v in parentView.subviews)
    {
        printSubViews(v, indent + 1);
    }
}

作业:

1. NavigationController Back Button

2. 给TabBarController设置图标、标题

3. statuBarStyle, UIViewController.view为什么会透到StatusBar下面

self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
    self.navigationController.navigationBar.translucent = YES;

navigationController1.tabBarItem = [[UITabBarItem alloc] initWithTitle: @"First"  image: [UIImage imageNamed: @"Third.png"] tag: 1000];
