objective-c – 在全屏模式下连接到NSView的NSView上的NSControl

>我的应用程序具有使用enterFullScreenMode：withOptions：设置为全屏模式的后台视图.

首选项视图来自XIB并包含NSControls,如复选框,圆形幻灯片,组合框,…

整个设置要复杂得多,这使得在此处发布代码变得非常困难.不过,如果您要求,我会添加一些部分.

问题：
当我选择首选项视图中的任何控件时,元素会闪烁.这意味着示例复选框消失并重新出现.
我已经尝试在视图的viewDidMoveToSuperview方法中解决运行setNeedsDisplay：,setNeedsLayout或makeKeyAndOrderFront的问题.虽然,没有任何帮助.我能做什么？

编辑1：
我拿了一个screen capture的应用程序,你可以看到会发生什么.

这是PreferencesViewController.h：

//  PreferencesViewController.h

#import <Cocoa/Cocoa.h>
#import "SlideShowModelProtocol.h"
#import "DisplayInfoController.h"

@interface PreferencesViewController : NSViewController {
    id<SlideShowModelProtocol> m_localModel;
    DisplayInfoController* m_displayInfoController;
}

@property (readonly) id<SlideShowModelProtocol> localModel;
@property (readwrite,assign) IBOutlet DisplayInfoController* displayInfoController;

- (void)moveViewToSuperview:(NSView*)superview;
- (void)showOnView:(NSView*)superview;
- (void)removeViewFromSuperview;
- (BOOL)viewHasSuperview;
- (void)updateModelSettings;
- (IBAction)cancelView:(id)sender;
- (IBAction)confirmView:(id)sender;

@end

…和实现PreferencesViewController.m：

//  PreferencesViewController.m

#import "PreferencesViewController.h"
#import "ApplicationController.h"
#import "DisplayInfo.h"


@interface PreferencesViewController()

    }
    return self;

@synthesize localModel = m_localModel;
@synthesize displayInfoController = m_displayInfoController;

- (void)loadModel {
    [self willChangeValueForKey:@"localModel"];
    // Retrieve deep copy of the model.
    m_localModel = [[[ApplicationController sharedController] model] copyWithZone:nil];
    // Reset the table view selection as saved in the model.
    NSIndexSet* selectionIndices = [NSIndexSet indexSetWithIndex:[[m_localModel selectedScreenIndex] unsignedIntegerValue]];
    [[m_displayInfoController displayInfoTableView] selectRowIndexes:selectionIndices byExtendingSelection:NO];
    [self didChangeValueForKey:@"localModel"];
}

/**

    [superview addSubview:[self view]];

}


- (void)centerViewOnSuperview {
    NSRect superviewFrame = self.view.superview.frame;
    NSRect viewFrame = self.view.frame;
    float viewFrameWidth = viewFrame.size.width;
    float viewFrameHeight = viewFrame.size.height;
    float xPos = 0.5f * superviewFrame.size.width - 0.5f * viewFrameWidth;
    float yPos = 0.5f * superviewFrame.size.height - 0.5f * viewFrameHeight;
    NSRect frame = NSMakeRect(xPos,yPos,viewFrameWidth,viewFrameHeight);
