iOS6 与iOS7以及7以上状态栏的颜色设置

iOS7默认状态栏文字颜色为黑色

修改为白色的方法：(chenyong注意 我的Status bar style 使用的仍是默认值Gray style(default))

1在Info.plist中设置View controller-based status bar appearance 为NO
2 在需要改变状态栏颜色的ViewController中在ViewDidLoad方法中增加：
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

如下：

- (void)viewDidLoad

{

    [super viewDidLoad];

    // Do any additional setup after loading the view from its nib.

    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];

}

如果需要在全部View中都变色，可以写在父类的相关方法中。

在使用Cordova的时候遇到的状态栏合并问题

- (void)viewWillAppear:(BOOL)animated

{

    // View defaults to full size.  If you want to customize the view's size, or its subviews (e.g. webView),

    // you can do so here.

    // 导航与状态栏合并的问题

    float currentVersion = [[[UIDevice currentDevice] systemVersion] floatValue];

    if (currentVersion >= ) {

        // bounds 是以自身的左上角为坐标原点

        CGRect viewBounds = [self.webView bounds];

        viewBounds.origin.y = ;

        viewBounds.size.height = viewBounds.size.height - ;

        self.webView.frame = viewBounds;

        self.view.backgroundColor = [UIColor blackColor];

    }

    [super viewWillAppear:animated];

}
