iOS 7-状态栏与视图内容重叠

Question

我在我的应用程序中使用状态栏，并希望维持ios 6和ios 7之间的兼容性。我希望状态栏的行为与ios 6相同。我不希望状态栏与视图控制器重叠。

Answer 1

Try adding the following code in your view's viewWillAppear function:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    // if this is ios7 this code will make the view appear properly below the navigation bar
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 7.0) {
        self.edgesForExtendedLayout = UIRectEdgeNone;
        self.extendedLayoutIncludesOpaqueBars = YES;
    }
}

Answer 2

Try this~

if(OVER_IOS7){
    self.edgesForExtendedLayout = UIRectEdgeNone;
    [self.navigationController.navigationBar setTranslucent:NO]
}

Answer 3

Try this.

add this key into info.plist file

View controller-based status bar appearance

set value for this to:- No

Answer 4

In iOS 7, the status bar is transparent, and other bars—that is, navigation bars, tab bars, toolbars, search bars, and scope bars—are translucent. As a general rule, you want to make sure that content fills the area behind the bars in your app.

Most bars also draw a blur behind them, unless you provide a custom background image for the bar.

iOS 7 introduces the barPosition property for identifying bar position, which helps you specify when a custom background image should extend behind the status bar. The UIBarPositionTopAttached value means that a bar is at the top of the screen and its background extends upward into the status bar area. In contrast, the UIBarPositionTop value means that a bar is at the top of its local context—for example, at the top of a popover—and that it doesn't provide a background for the status bar.

By default, all bar buttons are borderless. For details, see Bar Buttons.

The Status Bar

Because the status bar is transparent, the view behind it shows through. The style of the status bar refers to the appearance of its content, which includes items such as time, battery charge, and Wi-Fi signal. Use a UIStatusBarStyle constant to specify whether the status bar content should be dark (UIStatusBarStyleDefault) or light (UIStatusBarStyleLightContent):

UIStatusBarStyleDefault displays dark content. Use when light content is behind the status bar. image: ../Art/status_bar_default_iphone_2x.pngimage: ../Art/status_bar_default_ipad_2x.png UIStatusBarStyleLightContent displays light content. Use when dark content is behind the status bar. image: ../Art/status_bar_light_iphone_2x.pngimage: ../Art/status_bar_light_ipad_2x.png In some cases, the background image for a navigation bar or a search bar can extend up behind the status bar (for details, see Navigation Bar and Search Bar and Scope Bar). If there are no bars below the status bar, the content view should use the full height of the screen. To learn how to ensure that a view controller lays out its views properly, see Using View Controllers.

In iOS 7, you can control the style of the status bar from an individual view controller and change it while the app runs. If you prefer to opt out of this behavior and set the status bar style by using the UIApplication statusBarStyle method, add the UIViewControllerBasedStatusBarAppearance key to an app's Info.plist file and give it the value NO.
