我在使用UIImagePickerController时出现iOS 7 StatusBar问题允许编辑

概述我研究相关的iOS 7状态 – Bar Maintain,但我在使用UI ImagePickerController时遇到了问题.允许编辑“编辑窗口”在顶部栏显示20像素空间. 我使用了代码,首先我在info.plist中将UIViewControllerBasedStatusBarAppearance设置为NO并设置委托方法： Appdelegate.h @property (retain, n 我研究相关的iOS 7状态 – bar Maintain,但我在使用UI ImagePickerController时遇到了问题.允许编辑“编辑窗口”在顶部栏显示20像素空间.

我使用了代码,首先我在info.pList中将UIVIEwControllerBasedStatusBarappearance设置为NO并设置委托方法：

Appdelegate.h

@property (retain,nonatomic) UIWindow *background;

Appdelegate.m

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-20);    self.window.bounds = CGRectMake(0,self.window.frame.size.height);    background = [[UIWindow alloc] initWithFrame: CGRectMake(0,20)];    background.backgroundcolor =[UIcolor redcolor];    [background setHIDden:NO];}

在我的家庭视图控制器中没有任何效果,所以我放入了我的home vIEwController,一种用于更改状态栏背景颜色的方法：

-(voID)vIEwWillLayoutSubvIEws{if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {    self.vIEw.clipsToBounds = YES;    CGRect screenRect = [[UIScreen mainScreen] bounds];    CGfloat screenHeight = screenRect.size.height;    self.vIEw.frame = CGRectMake(0,self.vIEw.frame.size.wIDth,screenHeight-20);    self.vIEw.bounds = CGRectMake(0,self.vIEw.frame.size.height);    UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];    if ([[NSUserDefaults standardUserDefaults] boolForKey:@"userIsMale"]) {        [tempWindow setBackgroundcolor:[UIcolor colorWithRed:(46.0/255.0) green:(134.0/255.0) blue:(255.0/255.0) Alpha:1]];    }    else {        [tempWindow setBackgroundcolor:[UIcolor colorWithRed:(246.0/255.0) green:(26.0/255.0) blue:(113.0/255.0) Alpha:1]];    }    [[UIApplication sharedApplication] setStatusbarStyle:UIStatusbarStylelightContent];}

现在,当我呈现UIImagePickerController时,允许编辑窗口显示如下：

我尝试使用此解决方案为隐藏状态栏,同时呈现UIImagePickerController：

- (voID)navigationController:(UINavigationController *)navigationController willShowVIEwController:(UIVIEwController *)vIEwController animated:(BOol)animated{    [[UIApplication sharedApplication] setStatusbarHIDden:YES];}

并在VIEwWillApear中显示状态条形码.

我得到了这种结果：

我在哪里做错了,我该如何解决这个问题？

解决方法 尝试一下：

-(BOol)prefeRSStatusbarHIDden { return YES; }

它会隐藏状态栏.

在iOS 7上,如果要使用setStatusbarHIDden :,则需要在info.pList中将基于VIEw控制器的状态栏外观设置为NO.

我希望它会给你一些暗示.

编辑：

我发现了问题.

这是第一次在vIEwWillAppear上显示homeVIEwController时的日志：

(lldb) po [[UIApplication sharedApplication] windows]<__NSArrayM 0x8a74560>(<UIWindow: 0x8e33360; frame = (0 20; 320 548); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x8e348b0>; layer = <UIWindowLayer: 0x8e3c6e0>>,<UIWindow: 0x8c1db40; frame = (0 0; 320 20); gestureRecognizers = <NSArray: 0x8c1e170>; layer = <UIWindowLayer: 0x8c1da80>>)

这是解雇imagePicker并调用vIEwWillAppear后的日志：

(lldb) po [[UIApplication sharedApplication] windows]<__NSArrayM 0x8c1a700>(<UIWindow: 0x8e33360; frame = (0 0; 320 568); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x8e348b0>; layer = <UIWindowLayer: 0x8e3c6e0>>,<UIWindow: 0x8c1db40; frame = (0 0; 320 20); gestureRecognizers = <NSArray: 0x8c1e170>; layer = <UIWindowLayer: 0x8c1da80>>,<UITextEffectsWindow: 0x8c53380; frame = (0 0; 320 568); hIDden = YES; opaque = NO; gestureRecognizers = <NSArray: 0x8c538a0>; layer = <UIWindowLayer: 0x8c53520>>)

默认窗口大小已更改.这就是状态栏无法显示的原因.

我编辑了这样的代码,它对我有用：

- (voID)vIEwDIDLoad{    [super vIEwDIDLoad];    // Do any additional setup after loading the vIEw,typically from a nib.    //    [[UIApplication sharedApplication] setStatusbarHIDden:YES];    if(OVER_IOS7){        [self.navigationController.navigationbar setTranslucent:NO];    }}- (voID)dIDReceiveMemoryWarning{    [super dIDReceiveMemoryWarning];    // dispose of any resources that can be recreated.}- (voID)vIEwWillAppear:(BOol)animated{    [super vIEwWillAppear:animated];    [[UIApplication sharedApplication] setStatusbarHIDden:NO withAnimation:UIStatusBaranimationSlIDe];}-(voID)vIEwWillLayoutSubvIEws{    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {        self.vIEw.clipsToBounds = YES;        CGRect screenRect = [[UIScreen mainScreen] bounds];        CGfloat screenHeight = screenRect.size.height;        self.vIEw.frame = CGRectMake(0,screenHeight-20);        self.vIEw.bounds = CGRectMake(0,self.vIEw.frame.size.height);        UIWindow *defaultwindow = [[[UIApplication sharedApplication] windows] objectAtIndex:0];        defaultwindow.frame =  CGRectMake(0,320,548);        defaultwindow.bounds = CGRectMake(0,548);        UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];        if ([[NSUserDefaults standardUserDefaults] boolForKey:@"userIsMale"]) {            [tempWindow setBackgroundcolor:[UIcolor colorWithRed:(46.0/255.0) green:(134.0/255.0) blue:(255.0/255.0) Alpha:1]];        }        else {            [tempWindow setBackgroundcolor:[UIcolor colorWithRed:(246.0/255.0) green:(26.0/255.0) blue:(113.0/255.0) Alpha:1]];        }        [[UIApplication sharedApplication] setStatusbarStyle:UIStatusbarStylelightContent];    }}- (IBAction)showImagePicker:(ID)sender{    UIImagePickerController *picker = [[UIImagePickerController alloc] init];    [picker setSourceType:UIImagePickerControllerSourceTypeSavedPhotosAlbum];    [self presentVIEwController:picker animated:YES completion:^{        [[UIApplication sharedApplication] setStatusbarHIDden:YES withAnimation:UIStatusBaranimationSlIDe];    }];}
