In my NSPersistenDocument based project i have a structure like this
myDocument (NSPersistentDocument) -> myDocument.xib (windows xib) | |-> view (the self.view) --> ... "other view" | |-> some NSArrayController | |-> myResourceViewController --> myResourceViewController.xib | |-> view (the self.view) | |-> myTreeController (a NSTreeController subclass)
basically, myResourceViewController is an instance of a viewController who manage resourceView and manage their data.
in awakeFromNib method of myDocument i have the following code
- (void)windowControllerDidLoadNib:(NSWindowController *)aController
{
...
[leftBar addSubview:resourceViewController.view]; //i add resourceViewController's view
resourceViewController.view.frame = leftBar.bounds;
...
}
in myResourceViewController awakeFromNib methods i have:
-(void)awakeFromNib;
{
NSLog(@"%@", [self description]);
[removeButton bind:@"enabled" toObject:resourceTreeController withKeyPath:@"selection" options:[NSDictionary dictionaryWithObject:NSIsNotNilTransformerName forKey:NSValueTransformerNameBindingOption]];
NSArray *draggedTypes = [NSArray arrayWithObjects:ResourceURIPasteBoardType, nil];
[resourceOutlineView registerForDraggedTypes:draggedTypes];
}
the NSLog say that awakeFromNib, of the same instance of myResourceViewController, is called 4 time, i don't understand why. My only ResourceViewController is created in myDocument xib. I don't use NSNib loading methods everywhere.
解决方案
I found the solution. awakeFromNib is called every time a NSTableCellView is created by NSOutlineView.
在我NSPersistenDocument基于项目我有一个这样的结构
myDocument中（NSPersistentDocument） - GT; myDocument.xib（窗口XIB） | | - ＆GT;视图（self.view） - GT; ......另一种观点 | | - ＆GT;一些NSArrayController的 | | - ＆GT; myResourceViewController - ＆GT; myResourceViewController.xib | | - ＆GT;视图（self.view） | | - ＆GT; myTreeController（一NSTreeController子类）
基本上，myResourceViewController是谁管理的ResourceView和管理他们的数据的viewController的一个实例。
在myDocument中的awakeFromNib方法，我有以下code
- （无效）windowControllerDidLoadNib：（NSWindowController *）aController
{
...
[leftBar addSubview：resourceViewController.view]; //我添加resourceViewController的看法
resourceViewController.view.frame = leftBar.bounds;
...
}
在myResourceViewController awakeFromNib方法我有：
- （无效）awakeFromNib;
{
的NSLog（@％@，[自我描述]）; [removeButton绑定：@已启用toObject：resourceTreeController withKeyPath：@选择选项：[NSDictionary的dictionaryWithObject：NSIsNotNilTransformerName forKey：NSValueTransformerNameBindingOption]]; NSArray的* draggedTypes = [NSArray的arrayWithObjects：ResourceURIPasteBoardType，无]
[resourceOutlineView registerForDraggedTypes：draggedTypes];
}
在的NSLog说awakeFromNib，myResourceViewController的同一个实例中，被称为4时，我不明白为什么。我唯一ResourceViewController在厦门国际银行myDocument中创建。我不使用NSNib加载方式随处可见。
解决方案
我找到了解决办法。 awakeFromNib 被称为每次 NSTableCellView 是 NSOutlineView 创建
