-[NSWindowController窗口]在用窗口初始化NSWindowController时保留窗口吗？
|
在一个应用程序（OS X 10.6.7）中，我有一个用
-[NSWindowController initWithWindow:]
[self window]
[self window]
init
[self window]
NSWindowController
-loadWindow
-isWindowLoaded
YES
(gdb) set $window = (id)[self window]
Current language: auto; currently objective-c
(gdb) p (int)[$window retainCount]
$1 = 3
(gdb) p (BOOL)[self isWindowLoaded]
$2 = 1 \'\\001\'
(gdb) call (void)[self loadWindow]
(gdb) p (int)[$window retainCount]
$3 = 3
(gdb) p (int)[[self window] retainCount]
$4 = 4
(gdb) p (int)[[self window] retainCount]
$5 = 5

保留窗户就可以了；该问题似乎与自动释放池有关。window = [[NSWindow alloc] initWithContentRect:NSMakeRect(100, 100, 200, 200) styleMask:NSTitledWindowMask backing:NSBackingStoreBuffered defer:NO]; NSWindowController *controller = [[NSWindowController alloc] initWithWindow:window]; [window setTitle:@\"testing\"]; [window makeKeyAndOrderFront:nil]; [window release]; NSLog(@\"[window retainCount]: %d\", [window retainCount]); [controller window]; [controller window]; [controller window]; NSLog(@\"[window retainCount]: %d\", [window retainCount]); NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; [controller window]; [controller window]; [controller window]; NSLog(@\"[window retainCount]: %d\", [window retainCount]); [pool drain]; NSLog(@\"[window retainCount]: %d\", [window retainCount]);问题是我在Carbon事件处理程序（）中做可可时忘记了创建一个池。这与我链接到的线程的上下文匹配。 通常，当不存在自动释放池时，我会看到一个异常，因此我猜测那里只是一个永不耗尽的池。
