IOS7 状态栏和 Navigation Bar重叠的问题解决
一 Status bar重叠问题：
方法一：隐藏Status bar 在plist里面增加2个变量 Status bar is initially hidden -> YES View controller-based status bar appearance -> NO
方法二：改为和IOS6 一样的显示方式
Set
UIViewControllerBasedStatusBarAppearancetoNOininfo.plist(To opt out of having view controllers adjust the status bar style so that we can set the status bar style by using the UIApplicationstatusBarStyle method.)In AppDelegate's
application:didFinishLaunchingWithOptions, callif ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
[application setStatusBarStyle:UIStatusBarStyleLightContent];
self.window.clipsToBounds =YES;
self.window.frame = CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height-20); //Added on 19th Sep 2013
self.window.bounds = CGRectMake(0, 20, self.window.frame.size.width, self.window.frame.size.height);
}
方法三：
Set UIViewControllerBasedStatusBarAppearance to NO in info.plist
Pase this code in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
[application setStatusBarStyle:UIStatusBarStyleLightContent];
self.window.clipsToBounds =YES;
self.window.frame = CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height);
//Added on 19th Sep 2013
NSLog(@"%f",self.window.frame.size.height);
self.window.bounds = CGRectMake(0,0, self.window.frame.size.width, self.window.frame.size.height);
}
It may push down all your views by 20 pixels.To over come that use following code in -(void)viewDidAppear:(BOOL)animated method
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
CGRect frame=self.view.frame;
if (frame.size.height==[[NSUserDefaults standardUserDefaults] floatForKey:@"windowHeight"])
{
frame.size.height-=20;
}
self.view.frame=frame;
}
You have to set windowHeight Userdefaults value after window allocation in didFinishLauncing Method like
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[[NSUserDefaults standardUserDefaults] setFloat:self.window.frame.size.height forKey:@"windowHeight"];
二 Navigation Bar重叠的问题：
在页面刚生成的时候 initWithNibName 函数 或者其他函数中加一句话：
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
self.edgesForExtendedLayout = UIRectEdgeNone;
}
显示方式就和IOS6 一致了。
