ios - 状态栏背景颜色

Question

我正在使用 ios 7 我想设置状态栏背景图像。我已经这样做了，但它仍然没有改变任何东西:

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    UIView *addStatusBar = [[UIView alloc] init];
    addStatusBar.frame = CGRectMake(0, 0, 320, 20);
    addStatusBar.backgroundColor = [UIColor redColor]; //change this to match your navigation bar
    [self.window.rootViewController.view addSubview:addStatusBar];
}

Answer 1

我已经像 .h 文件那样做了

@property (retain, nonatomic) UIWindow *statusBarBackground;

在.m文件中

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    self.statusBarBackground = [[UIWindow alloc] initWithFrame: CGRectMake(0, 0, self.window.frame.size.width, 20)];
    self.statusBarBackground.backgroundColor =[UIColor colorWithPatternImage:[UIImage imageNamed:@"statusbar_bg"]];
    [self.statusBarBackground makeKeyAndVisible];
}

将此添加到您的 Controller

- (void) viewDidLayoutSubviews {
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
        CGRect viewBounds = self.view.bounds;
        if (viewBounds.origin.y == 0) {
            CGFloat topBarOffset = self.topLayoutGuide.length;
            viewBounds.origin.y -= topBarOffset;
            self.view.bounds = viewBounds;
        }
    }
}
