在iOS 7中，UIStatusBar被设计成这样，它与视图合并:
(GUI由Tina tavvar设计)
It is cool, but it will somewhat mess up your view when you have something at the top part of your view, and it becomes overlapped with the status bar.
Is there a simple solution (such as setting a property in info.plist) that can change the way it works [not overlapping] back to how it is in iOS6?
I know a more straightforward solution is to have self.view.center.x + 20 points for every single view controller, but changing them will screw other dimensions up (having a different self.view.center.x can cause problem to custom segues, etc.) and suddenly it turns into a tedious job that is best to be avoided.
I'll really be glad if someone can provide me an one-liner solution for this.
附注:我知道我可以隐藏状态栏
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
在didFinishLaunchingWithOptions方法中，但这是一个变通方法，一个避免问题的快捷方式，所以我不认为这是一个真正的解决方案。
为了继续使用setStatusBarHidden:我使用这个类别:
@interface UIApplication (StatusBar)
-(void)setIOS7StatusBarHidden:(BOOL)statusBarHidden;
@end
@implementation UIApplication (StatusBar)
-(void)setIOS7StatusBarHidden:(BOOL)statusBarHidden{
if (!IOS7) {
[self setStatusBarHidden:statusBarHidden];
return;
}
if ([self isStatusBarHidden] == statusBarHidden) {
return;
}
[self setStatusBarHidden:statusBarHidden];
[self keyWindow].clipsToBounds = YES;
CGFloat offset = statusBarHidden ? 0 : 20;
[self keyWindow].frame = CGRectMake(0,offset,[self keyWindow].frame.size.width,[self keyWindow].frame.size.height-offset);
[self keyWindow].bounds = CGRectMake(0, offset, [self keyWindow].frame.size.width,[self keyWindow].frame.size.height);
}
@end
我要迟到了，但我只是想分享我所做的，基本上
最简单的解决方案
首先->转到你的信息。plist文件并添加状态栏样式->透明黑色样式(Alpha 0.5)
现在，它开始了:-
在你的AppDelegate.m中添加这段代码
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//Whatever your code goes here
if(kDeviceiPad){
//adding status bar for IOS7 ipad
if (IS_IOS7) {
UIView *addStatusBar = [[UIView alloc] init];
addStatusBar.frame = CGRectMake(0, 0, 1024, 20);
addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //change this to match your navigation bar
[self.window.rootViewController.view addSubview:addStatusBar];
}
}
else{
//adding status bar for IOS7 iphone
if (IS_IOS7) {
UIView *addStatusBar = [[UIView alloc] init];
addStatusBar.frame = CGRectMake(0, 0, 320, 20);
addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //You can give your own color pattern
[self.window.rootViewController.view addSubview:addStatusBar];
}
return YES;
}
对于Archy Holt的回答，有一个小的选择，更简单一点:
a.在info.plist中设置“UIViewControllerBasedStatusBarAppearance”为“NO”
b.在AppDelegate的应用程序didFinishLaunchingWithOptions:中调用:
if ([[UIDevice currentDevice].systemVersion floatValue] < 7)
{
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
}
else
{
// handling statusBar (iOS7)
application.statusBarStyle = UIStatusBarStyleLightContent;
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
self.window.clipsToBounds = YES;
// handling screen rotations for statusBar (iOS7)
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationDidChangeStatusBarOrientationNotification:) name:UIApplicationDidChangeStatusBarOrientationNotification object:nil];
}
并添加方法:
- (void)applicationDidChangeStatusBarOrientationNotification:(NSNotification *)notification
{
// handling statusBar (iOS7)
self.window.frame = [UIScreen mainScreen].applicationFrame;
}
你也可以考虑子类化UIWindow来处理UIApplicationDidChangeStatusBarOrientationNotification本身。
