大佬教程收集整理的这篇文章主要介绍了我在使用UIImagePickerController时出现iOS 7 StatusBar问题允许编辑，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
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？
-(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>> )
- (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]; }]; }
