如何在自定义视图中禁用用户互动 [英] How to disable user interaction in a custom View

问题描述

我有一个自定义视图 NSView ，我想禁用用户交互，但我不知道如何这样做。

I have a custom View NSView and I want to disable userinteraction, but I'm not sure how to do this.

我的想法是：

[myView setEnabled:NO];

但它是错误的，不工作。

but it's wrong and doesn't work. How can I make it so that, it's just visible for the user, and nothing else?

@implementation NSView(DisableSubsAdditions)

- (void)disableSubViews
{
    [self setSubViewsEnabled:NO];
}

- (void)enableSubViews
{
    [self setSubViewsEnabled:YES];
}

- (void)setSubViewsEnabled:(BOOL)enabled
{
    NSView* currentView = NULL;
    NSEnumerator* viewEnumerator = [[self subviews] objectEnumerator];

    while( currentView = [viewEnumerator nextObject] )
    {
        if( [currentView respondsToSelector:@selector(setEnabled:)] )
        {
            [(NSControl*)currentView setEnabled:enabled];
        }
        [currentView setSubViewsEnabled:enabled];

        [currentView display];
    }
}
