Creating window with a NSTextView programmatically - objective-c

Question

I wish to create a window without a nib file which consists entirely of an NSTextView.
It should act as a popup but still be modeless.
So far I have two properties:
#property (strong,nonatomic) NSWindow *consoleWindow;
#property (strong,nonatomic) NSTextView* textView;
Here is what my implementation looks like:
-(void)doubleAction:(NSOutlineView*)sender
{
if(self.currentLogEntry == nil)
{
return;
}
self.consoleWindow = nil;
self.textView = nil;
NSRect windowRect = NSMakeRect(10.0f, 10.0f, 500.0f, 400.0f);
self.consoleWindow = [[NSWindow alloc] initWithContentRect:windowRect
styleMask:( NSResizableWindowMask | NSClosableWindowMask | NSTitledWindowMask)
backing:NSBackingStoreBuffered defer:NO];
self.textView = [[NSTextView alloc] initWithFrame:[[self.consoleWindow contentView] frame]];
[self.textView setString:self.currentLogEntry.value];
[self.consoleWindow setContentView:self.textView];
[self.consoleWindow makeKeyAndOrderFront:nil];
[self.consoleWindow makeFirstResponder:self.textView];
NSLog(#"Double clicked");
}
Things have been wired up so I have a list of entries, whenever I double click on an entry the selected entry is loaded into self.currentLogEntry and this method is then fired. It works but if I close the window and try to open another entry I get Thread 1:EXC_BAD_ACCESS (code=EXC_I386_GPFLT)
I think it has something to do with the window not being released properly but I have tried a few things like setting the properties to nil whenever the program enters the doubleAction (as you can see in the code) but that doesn't help.
Any help solving this problem is greatly appreciated.

Answer 1

The soulution was to: [self.consoleWindow setReleasedWhenClosed:NO];
Here is how the full code ended out being (only relevant parts):
.h:
#property (strong,nonatomic) NSWindow *consoleWindow;
#property (strong,nonatomic) NSTextView* textView;
#property (strong,nonatomic) NSScrollView* scrollView;
.m:
-(void)doubleAction:(NSOutlineView*)sender
{
if(self.currentLogEntry == nil)
{
return;
}
self.consoleWindow = nil;
self.textView = nil;
self.scrollView = nil;
NSRect windowRect = NSMakeRect(10.0f, 10.0f, 500.0f, 400.0f);
self.consoleWindow = [[NSWindow alloc] initWithContentRect:windowRect
styleMask:( NSResizableWindowMask | NSClosableWindowMask | NSTitledWindowMask)
backing:NSBackingStoreBuffered defer:NO];
[self.consoleWindow setReleasedWhenClosed:NO];
self.scrollView = [[NSScrollView alloc] initWithFrame:[[self.consoleWindow contentView] frame]];
[self.scrollView setBorderType:NSNoBorder];
[self.scrollView setHasVerticalScroller:YES];
[self.scrollView setHasHorizontalScroller:NO];
[self.scrollView setAutoresizingMask:NSViewWidthSizable |
NSViewHeightSizable];
NSSize contentSize = [self.scrollView contentSize];
self.textView = [[NSTextView alloc] initWithFrame:NSMakeRect(0, 0,
contentSize.width, contentSize.height)];
[self.textView setMinSize:NSMakeSize(0.0, contentSize.height)];
[self.textView setMaxSize:NSMakeSize(FLT_MAX, FLT_MAX)];
[self.textView setVerticallyResizable:YES];
[self.textView setHorizontallyResizable:NO];
[self.textView setAutoresizingMask:NSViewWidthSizable];
[[self.textView textContainer]
setContainerSize:NSMakeSize(contentSize.width, FLT_MAX)];
[[self.textView textContainer] setWidthTracksTextView:YES];
[self.textView setString:self.currentLogEntry.value];
[self.scrollView setDocumentView:self.textView];
[self.consoleWindow setContentView:self.scrollView];
[self.consoleWindow makeKeyAndOrderFront:nil];
[self.consoleWindow makeFirstResponder:self.textView];
NSLog(#"Double clicked");
}
