直接上代码；对UIImagePickerController扩展：

////  UIImagePickerController+StatusBarHidden.m//  ////  Created by fangmi-huangchengda on 15/7/28.////#import "UIImagePickerController+StatusBarHidden.h"#import <objc/runtime.h>@implementation UIImagePickerController (StatusBarHidden)- (void)viewDidLoad{    [super viewDidLoad];    [self setHidetatusBar:YES];    [self performSelector:@selector(hideStatusBar) withObject:nil afterDelay:0.5];}- (BOOL)prefersStatusBarHidden{    if ([self hidetatusBar]) {        BOOL hide = (self.sourceType== UIImagePickerControllerSourceTypeCamera)? YES : NO;        return hide;    }    return NO;}- (UIViewController *)childViewControllerForStatusBarHidden{    if ([self hidetatusBar]) {        return nil;    }    return [self.childViewControllers lastObject];}- (void)setHidetatusBar:(BOOL)hidetatusBar{    objc_setAssociatedObject(self, (__bridge const void *)(@"hidetatusBar"), [NSNumber numberWithBool:hidetatusBar], OBJC_ASSOCIATION_RETAIN_NONATOMIC);}-(BOOL)hidetatusBar{    NSNumber  *hidetatusBar = objc_getAssociatedObject(self, (__bridge const void *)(@"hidetatusBar"));    return [hidetatusBar boolValue];}- (void)hideStatusBar{    [self setHidetatusBar:YES];    [self prefersStatusBarHidden];    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];    }}- (void)showStatusBar{    [self setHidetatusBar:NO];    [self prefersStatusBarHidden];    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];    }}@end

最后需要配置info.plist设置“View controller-based status bar appearance”为NO
