NSTableView 和 NSMutableArray 之间的 Cocoa 绑定拒绝更新

好吧，我对 Obj-C 和 Cocoa 很陌生，但我确信我在这里的绑定是正确的。我一直在谷歌搜索，搜索堆栈溢出，并一次又一次地检查我的值。

所以，这是我的绑定：

它们连接到此类：

@interface TMMaddMangaWindowDelegate : NSWindowController {
...
}
...
@property (copy) NSMutableArray* mangaList;
...
@end



@implementation TMMaddMangaWindowDelegate
...
@synthesize mangaList;
// - (NSMutableArray*) mangaList {
//   NSLog(@"mangaList was called!");
//   return mangaList;
//}
//- (void) setMangaList:(NSMutableArray *) input{
//  NSLog(@"setMangaList was called!");
//  [mangaList autorelease];
//  mangaList = [input retain];
//}
...
-(void) populateList:(NSArray*)list{
    NSMutableArray* newArray = [[NSMutableArray alloc] initWithArray:list];
    NSLog(@"Populating List.");
    for(NSXMLNode* node in list){
        [newArray addObject:node.description];
        //[[self mutableArrayValueForKey:@"mangaList"] addObject:node.description];
            //NSLog(@"%@", node.description);
    }
    [self setMangaList:newArray];
    [[self chapterListDownloadIndicator] stopAnimation:self];
}

如您所见，我还尝试了 mutableArrayValueForKey方法，但一无所获。我知道事实上 mangaList 正在获得物品。

我已经为此工作了一段时间，并且可能犯了一个愚蠢的错误。

提前致谢。

Ok, I'm very new to Obj-C and Cocoa, but I'm sure my bindings here are correct. I've been googling, searching stack overflow and have checked my values again and again.

So, here are my bindings:

They connect to this class:

@interface TMMaddMangaWindowDelegate : NSWindowController {
...
}
...
@property (copy) NSMutableArray* mangaList;
...
@end



@implementation TMMaddMangaWindowDelegate
...
@synthesize mangaList;
// - (NSMutableArray*) mangaList {
//   NSLog(@"mangaList was called!");
//   return mangaList;
//}
//- (void) setMangaList:(NSMutableArray *) input{
//  NSLog(@"setMangaList was called!");
//  [mangaList autorelease];
//  mangaList = [input retain];
//}
...
-(void) populateList:(NSArray*)list{
    NSMutableArray* newArray = [[NSMutableArray alloc] initWithArray:list];
    NSLog(@"Populating List.");
    for(NSXMLNode* node in list){
        [newArray addObject:node.description];
        //[[self mutableArrayValueForKey:@"mangaList"] addObject:node.description];
            //NSLog(@"%@", node.description);
    }
    [self setMangaList:newArray];
    [[self chapterListDownloadIndicator] stopAnimation:self];
}

As you can see, I also tried the mutableArrayValueForKey approach, which yielded nothing. I know for a fact mangaList is gaining items.

I've been working on this for a while, and probably made a stupid mistake.

Thanks in advance.

看起来您正在数组控制器背后更改 mangaList 。每当您对 mangaList 进行更改时，您应该首先调用 [self willChangeValueForKey:@"mangaList"];，然后调用 [self didChangeValueForKey:@"mangaList"] ; 完成更改后。这将使阵列控制器知道它需要查看发生了什么变化。
