如何在自定义视图中禁用用户交互

Question

我有一个自定义视图NSView,我想禁用userinteraction,但我不知道如何做到这一点.

我的想法是:

[myView setEnabled:NO];

但这是错误的,不起作用.我怎样才能做到这一点,它只对用户可见,而不是别的什么？

Answer 1

NSView没有setEnabled:或setIgnoresMouseEvents:

实现返回的hitTest:方法nil.

@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];
    }
}
