我有什么办法可以解决它。 

  NavigationControllerWithSlider* controller = (NavigationControllerWithSlider*) self.ViewLocations;    // ViewLocations ----> subView of ViewController && NavigationControllerWithSlider is a ViewController .


 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setRightSlidingViewWithSliderImage:length:]: unrecognized selector sent to instance 0x805df60'
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception
(lldb)

这是我的代码：

//ViewController.m

NavigationControllerWithSlider* controller = (NavigationControllerWithSlider*) self.ViewLocations;    // ViewLocations ----> subView of ViewController
    UIImage * img = [UIImage imageNamed: @"open_panel.png"];
    UIImage * closeImg = [UIImage imageNamed: @"close_panel.png"];

    UIImage * img1 = [UIImage imageWithCGImage:img.CGImage scale:img.scale orientation:UIImageOrientationUpMirrored];
    UIImage * closeImg1 = [UIImage imageWithCGImage:closeImg.CGImage scale: closeImg.scale orientation:UIImageOrientationUpMirrored];

    [controller setRightSlidingViewWithSliderImage:img1 length:300.0f];
    controller.rightSlidingViewControllerId = @"toBeEmbeddedRight";
    controller.rightSlidingView.hideSliderImage = closeImg1;
    controller.rightSlidingView.headPadding = 44.0f;
    controller.rightSlidingView.trailPadding = 44.0f;

//NavigationControllerWithSlider.m

- (void) setRightSlidingViewWithSliderImage: (UIImage*) image length: (CGFloat) length {
    _rightSlidingView = [[SlidingViewController alloc] initWithPosition: DDSliderPositionRight image: image length: length];
    _rightSlidingViewControllerId = @"";
}

我在这里缺少什么..？任何帮助请......

You are casting an object to NavigationControllerWithSlider, but my guess is that object is not really a NavigationControllerWithSlider. Can you add a log in above calling setRightSlidingViewWithSliderImage

NSLog(@"Class of controller: %@", NSStringFromClass([controller class]));

(or just let us know what self.ViewLocations is declared as)

因此，您必须将 NavigationControllerWithSlider 的实例显式设置为客户端视图控制器。为此，您可以使用以下方法或类似方法：

@interface NavigationControllerWithSlider : UINavigationController

// some custom interface
// ..

- (void)setRightSlidingViewWithSliderImage:(UIImage *)image length:(CGFloat)length;

@end

// this is the main controller with strong property of NavigationControllerWithSlider instance
@interface MainRootViewController

@property (nonatomic, strong) NavigationControllerWithSlider *sliderController;

@end

@implementation MainRootViewController

- (id)init {
    self = [super init];
    if (self) {
        _sliderController = [NavigationControllerWithSlider new];
    }

    return self;
}

- (void)presentPopup {
    SomeController *newControllerForPopup = [[SomeController alloc] init];
    newControllerForPopup.sliderController = self.slider;

    // present controller and use slider ^ that you've set here explicitly
}

@end

// here is an example of using and declaring of public property
@interface SomeController : UIViewController

@property (nonatomic, weak) NavigationControllerWithSlider *sliderController;

@end

@implementation SomeController

- (void)viewDidLoad {
    [super viewDidLoad];

    // do some additional view configuration using self.sliderController
}

@end
