獲取NSWindow的所有視圖和子視圖

有沒有一種方法可以獲得NSWindow的所有視圖和子視圖以及這些子視圖的子視圖（您明白...）？獲取NSWindow的所有視圖和子視圖

謝謝。

歡迎的StackOverflow！爲什麼不把用戶名從user635064更改爲更獨特的東西？此外，如果您標記正確答案，您將更有可能獲得幫助。 – Moshe 2011-03-27 03:08:00

同意關於用戶名，但不知道爲什麼你告訴我關於標記問題是否正確？我總是標記一個正確的問題，如果它幫助我... – user635064 2011-03-27 03:29:52

@用戶彼得是正確的。 – Moshe 2011-03-27 04:42:50

這裏是一個NSView類別：

@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

隨着我視圖層次創建了一個快速筆尖文件，它印刷本：

[RecursiveSubviewsAppDelegate awakeFromNib] allSubviews == (
    "<NSView: 0x10390dfd0>", 
    "<NSView: 0x103c07ae0>", 
    "<NSView: 0x100129cc0>", 
    "<NSButton: 0x100115ce0>", 
    "<NSButton: 0x100116900>", 
    "<NSButton: 0x1001165c0>", 
    "<NSButton: 0x100116130>", 
    "<NSButton: 0x100114ad0>", 
    "<NSButton: 0x100115910>", 
    "<NSButton: 0x100115090>", 
    "<NSScrollView: 0x103b07a30>", 
    "<NSClipView: 0x103b07d40>", 
    "<NSTextView: 0x103b083c0>\n 
Frame = {{0.00, 0.00}, {159.00, 58.00}}, 
Bounds = {{0.00, 0.00}, {159.00, 58.00}}\n 
Horizontally resizable: NO, Vertically resizable: YES\n 
MinSize = {159.00, 58.00}, MaxSize = {463.00, 10000000.00}\n", 
    "<NSScroller: 0x1001145b0>", 
    "<NSScroller: 0x100114840>", 
    "<NSScrollView: 0x10390ea00>", 
    "<NSClipView: 0x10390ef10>", 
    "<NSTableView: 0x10390f570>", 
    "<NSScroller: 0x103b06f10>", 
    "<NSScroller: 0x103b07460>", 
    "<NSClipView: 0x1039105d0>", 
    "<NSTableHeaderView: 0x103910300>", 
    "<_NSCornerView: 0x103911c20>"

一個問題的筆記我要補充的是，這是我不清楚如何做到這一點是有用的，但作爲調試工具。但即使如此，可能還有更簡單的做事方式。

適用於iOS：NS - > UI。 – clozach 2012-08-28 16:24:46

如果我正確理解了你，你將不得不創建一個遞歸調用自己的方法。事情是這樣的：

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

你會再調用類似

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

，讓您的觀點。（不要忘記，如果你不使用GC做內存管理。）

遞歸方法將永遠不會像您設計的那樣結束。 – Moshe 2011-03-27 03:10:11

謝謝，雖然這將無限地遞歸，直到堆棧溢出，我會添加一個基本情況。但這是最好的方式嗎？ – user635064 2011-03-27 03:32:23

@Enchilada：不要忘記釋放陣列。 @ user635064：不，它不會無限遞歸。如果你添加了一個視圖作爲它自己的子視圖的子視圖，那麼它可能是一個閉環，不能從窗口的'contentView'到達。 – 2011-03-27 03:41:45

不確定其他答案中的無限遞歸，但是當您在其上進行快速枚舉時絕對不能修改數組。下面是我爲iOS編寫的一個方法，它遍歷所有子視圖，直到沒有更多的東西需要探索。我認爲相同或相似的工作對於NSView。希望這可以幫助。

（編輯：現在......如果我剛剛看了一點點進一步下跌我的搜索結果，我早就發現了這個非常簡單的方法，首先做到這一點：How can I loop through all subviews of a UIView, and their subviews and their subviews）

- (NSMutableArray *)allSubviewsInView:(UIView *)parentView { 

    NSMutableArray *allSubviews  = [[NSMutableArray alloc] initWithObjects: nil]; 
    NSMutableArray *currentSubviews = [[NSMutableArray alloc] initWithObjects: parentView, nil]; 
    NSMutableArray *newSubviews  = [[NSMutableArray alloc] initWithObjects: parentView, nil]; 

    while (newSubviews.count) { 

     [newSubviews removeAllObjects]; 

     for (UIView *view in currentSubviews) { 

      for (UIView *subview in view.subviews) [newSubviews addObject:subview]; 

     } 

     [currentSubviews removeAllObjects]; 
     [currentSubviews addObjectsFromArray:newSubviews]; 
     [allSubviews addObjectsFromArray:newSubviews]; 

    } 

    NSLog(@"\n%d total subviews:\n%@",allSubviews.count, allSubviews); 

    return allSubviews; 

}

如果視圖內有視圖，上述解決方案將不起作用。我們需要做一個遞歸解決方案，如下所示。

-(void) printViewHierarchy: (UIView *) view withTag: (NSInteger) tag { 
 
    if (view == nil) { 
 
    return; 
 
    } 
 
    if (view == nil || [view tag] == tag) { 
 
    NSLog(@"%@", view); 
 
    return; 
 
    } 
 
    for (UIView * subview in [view subviews]) { 
 
    [self printViewHierarchy: subview withTag: tag]; 
 
    } 
 
} 
 

 
- (void) findAllViews { 
 
    
 
    UIView * baseView = [UIView new]; 
 
    [baseView setTag: 1]; 
 
    
 
    UIView * secondRowA = [UIView new]; 
 
    [secondRowA setTag: 2]; 
 
    
 
    UIView * secondRowB = [UIView new]; 
 
    [secondRowB setTag: 3]; 
 
    
 
    UIView * thirdRowA = [UIView new]; 
 
    [thirdRowA setTag: 4]; 
 
    
 
    UIView * thirdRowB = [UIView new]; 
 
    [thirdRowB setTag: 5]; 
 
    
 
    [secondRowA addSubview: thirdRowA]; 
 
    [secondRowB addSubview: thirdRowB]; 
 
    
 
    [baseView addSubview: secondRowA]; 
 
    [baseView addSubview: secondRowB]; 
 
    
 
    [self printViewHierarchy: baseView withTag: 6]; 
 
}
