Question

我有两个NSTextViews。一个在self.view上，另一个在scrollView的子视图（即FlippedView）上，是自我视图的一部分。

self.view中的NSTextView（即textViewInSelf）可以正确响应鼠标点击，我可以输入并选择文本。 FlippedView上的那个（即textViewInFlippedView）不响应鼠标。光标将形状更改为（I）...意味着已准备好键入文本，但没有任何反应。（以下示例代码）

在程序的另一部分中，我可以输入文本，但是当我想拖动并选择部分类型文本时，没有任何反应（没有示例代码）。

有什么想法吗？在此先感谢。

AppDelegate.h

#import <Cocoa/Cocoa.h>
#import "myViewController.h"

@interface AppDelegate : NSObject <NSApplicationDelegate> {
    FlippedView *flippedView;
}
@property (assign) IBOutlet NSWindow *window;
@property (strong) IBOutlet NSViewController *myViewController;
@property (weak) IBOutlet NSView *myCustomView;
@property(readwrite, strong, nonatomic) IBOutlet NSScrollView* scrollView;
@property(readwrite, strong, nonatomic) IBOutlet FlippedView *objCodeView;

我必须使用包含所有其他视图的视图设置主窗口的内容，我必须将窗口的设置放在awakeFromNib上，但我不确定这是否有所不同。

- (void)awakeFromNib {

    NSView *windowView = [[NSView alloc]initWithFrame:_window.frame];
    [windowView addSubview:controlView];
    [windowView addSubview:scrollView];
    [_window setContentView:windowView];
}

NSTextView不响应鼠标选择
