iOS StatusBar状态栏文字颜色更改

1、将单个页面的StatusBar文字颜色改为白色，动态更改也可以在这里设置

-(UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleLightContent;
}

2、将所有页面的StatusBar文字颜色改为白色

　　plist文件中View controller-based status bar appearance 设置为 NO

　　在这种情况下，将单个页面的文字颜色更改为黑色

-(void)viewWillAppear:(BOOL)animated {
    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleDefault;
}

-(void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleDefault;
}

3、scrollView滑动更改StatusBar的文字颜色

-(void)scrollViewDidScroll:(UIScrollView *)scrollView {
    _offsetY = scrollView.contentOffset.y;
    [self setNeedsStatusBarAppearanceUpdate];   //更新statusBar颜色，调用preferredStatusBarStyle
}

- (UIStatusBarStyle)preferredStatusBarStyle {
    if (_offsetY <= 136) {
        return UIStatusBarStyleLightContent;
    }
    return UIStatusBarStyleDefault;
}
