Objective c 获取NSWindow的所有视图和子视图

是否有一种方法可以获取NSWindow的所有视图和子视图以及这些子视图的子视图（您知道了…）

---

谢谢。

如果我理解正确，您必须创建一个递归调用自身的方法。大概是这样的：

- (NSArray *)allSubviewsOfView:(NSView *)view
{
  NSMutableArray *subviews = [[view subviews] mutableCopy];
  for (NSView *subview in [view subviews])
    [subviews addObjectsFromArray:[self allSubviewsOfView:subview]]; //recursive
  return subviews;
}

然后你会称之为

NSArray *allSubviewsOfWindow = [self allSubviewsOfView:[window contentView]];

---

了解你的观点。（如果不使用GC，请不要忘记进行内存管理。）

NSView上有一个类别：

@interface NSView (MDRecursiveSubviews)
- (NSArray *)allSubviews;
@end

@implementation NSView (MDRecursiveSubviews)

- (NSArray *)allSubviews {
    NSMutableArray *allSubviews = [NSMutableArray arrayWithObject:self];
    NSArray *subviews = [self subviews];
    for (NSView *view in subviews) {
        [allSubviews addObjectsFromArray:[view allSubviews]];
    }
    return [[allSubviews copy] autorelease];
}

@end

通过使用视图层次结构创建的快速nib文件，它打印了以下内容：

[RecursiveSubviewsAppDelegate awakeFromNib] allSubviews == (
    "<NSView: 0x10390dfd0>",
    "<NSView: 0x103c07ae0>",
    "<NSView: 0x100129cc0>",

我需要补充的一点是，除了作为调试工具外，我不清楚这将如何发挥作用。但即便如此，可能还有更简单的方法来做事情。

在其他答案中不确定无限递归，但在对数组进行快速枚举时，您肯定不能修改数组。下面是我编写的一个方法te for iOS，迭代所有子视图，直到没有更多的子视图可供探索。我认为相同或类似的方法适用于NSView。希望这能有所帮助

（编辑：现在……如果我只是在我的搜索结果中再往下看一点，我会首先找到一个非常简单的方法：）

有一条私人消息可以在

NSView

上发送以打印控制层次结构

[NSView\u subtreeDescription]

提供了

NSView

的整个层次结构，即其子级及其子级。

静态无效转储视图（NSView*v，int级别）{
static void dumpViews(NSView* v, int level) {
    NSString* indent = @"";
    for (int i = 0; i < level; i++) {
        indent = [indent stringByAppendingString:@"    "];
    }
    NSLog(@"%@%@ %@", indent, [v class], NSStringFromRect(v.frame));
    if (v.subviews != null) {
        for (id s in v.subviews) {
            dumpViews(s, level + 1);

    }

如果视图中存在视图，则上述解决方案将不起作用。我们需要执行如下所示的递归解决方案

如果（视图==nil | |[视图标记]==tag）{
NSLog（@“%@”，视图）；

欢迎使用StackOverflow！为什么不将您的用户名从user635064更改为更独特的名称？此外，如果您标记正确的答案，您将更有可能获得帮助。同意用户名，但不知道您为什么要告诉我将问题标记为正确？如果问题对我有帮助，我总是将问题标记为正确…只需添加您的v查看NSMutableArray以供稍后枚举。递归方法永远不会像您设计的那样结束。谢谢，虽然这将无限递归直到堆栈溢出，但我将添加一个基本大小写。但这是最好的方法吗？@Enchilada:别忘了释放数组。@user635064:不，它不会无限递归。如果您将视图添加为subv，它可能会无限递归查看它自己的一个子视图，但这将是一个封闭的循环，无法从窗口的

contentView

@Enchilada:此方法的真正问题不是它无限递归，而是您正在枚举一个正在变异的数组。呸，无法编辑我以前的注释。这里有一个更好的：@Moshe:它只会递归一个数组因此，除非您可以创建nib文件或以编程方式创建具有无限多个子视图的视图层次结构（其行为将导致“第一个”无限递归，而不是调用该方法时遇到的任何递归），否则没有无限递归。OP正在查找子视图及其子视图（我猜是等）。也适用于iOS:NS->UI。不适用于ARC:**-[NSMutableArray addObjectsFromArray:::]：数组参数不是NSArray“更简单的操作方式”只需将视图添加到NSMutableArray，并在更大的范围内访问该NSMutableArray，这样做的效率也要高得多。
