Question

我正在通过mach_inject编写一个插件，将项目添加到Finder上下文菜单中。我已经通过挂钩NSMenu成功添加了它。但现在我需要获取右键单击的项目。有人说我们可以使用下面的代码，但它只能获取所选项目而不是右键单击项目（它们是不同的!!!!在Finder中，如果您选择一个项目并右键单击另一个项目，则所选项目赢了不要改变。任何人都知道如何在Finder中获得右键单击项目？谢谢！

SBElementArray * selection = [[finder selection] get];

NSArray * items = [selection arrayByApplyingSelector:@selector(URL)];
for (NSString * item in items) {
    NSURL * url = [NSURL URLWithString:item];
    NSLog(@"selected item url: %@", url);
}

在获取所选文件之前，您应准备一些帮助代码

struct TFENode {
struct OpaqueNodeRef *fNodeRef;
};

struct TFENodeVector {
    struct TFENode *_begin;
    struct TFENode *_end;
    struct TFENode *_end_cap;
};

- (NSArray *)arrayForNodeVector:(const struct TFENodeVector *)vector
{
    NSInteger capacity = vector->_end - vector->_begin;
    NSMutableArray *array = [[NSMutableArray alloc] initWithCapacity:capacity];
    struct TFENode *node;
    for (node = vector->_begin; node < vector->_end; ++node) {
        [array addObject: [self pathForNode:node]];
    }
    return array;
}

你可以获得这样的文件

// Snow Leopard & Lion
// gNodeHelper is where you put above code
// override_handleContextMenuCommon: is your override function

+ (void)override_handleContextMenuCommon:(unsigned int)context
                                   nodes:(const struct TFENodeVector *)nodes
                                   event:(id)event
                                    view:(id)view
                        windowController:(id)windowController
                              addPlugIns:(BOOL)flag
{
    NSArray *paths = [gNodeHelper arrayForNodeVector:nodes];

    [self override_handleContextMenuCommon:context
                                     nodes:nodes
                                     event:event
                                     view:view
                         windowController:windowController
                               addPlugIns:flag];

}
