TimeDrawer に、Mail.app の振り分けルールのような「ルール」を実装。現在テスト中。オブジェクトコントローラの使い方とか、正しい（正答）かどうかわからないのですが、とにかくバインディングとNSPredicateで結構簡単にできました。

Spotlight ( mdimport )がファイルの更新を監視しているのはこの機構を使用していると思われる。10.5 では一般向けのAPI が実装される模様。

Tue, 14 Aug 2007 21:45:10 +1200

Vector, Mac用のアプリケーション紹介用サイトとしては既に死んでいます。登録に１ヶ月必要という、なんともな仕様。そんなサイトで、JPO mdimporter がMacビジネス部門第３位でした。多分ダウンロードした人の99%はウインドウズ用のソフトウェアだと思っているはず。

Get kMDItemTextContent Value

Tue, 14 Aug 2007 20:53:31 +1200

You cannot retrieve kMDItemTextContent value from Spotlight query result.

Using these method below, mdimporter plugins can be used as viewer plugins for all the documents that the plugins support.

Load Nib File/別のNibを読み込む

Tue, 14 Aug 2007 20:49:22 +1200

(1)Create nib by IB

Make File's Owner a Custom Class e.g. HogeClass

Name this nib as Hoge.nib in this example.

(2)Create these files

HogeClass.h

HogeClass.m

HogeClass.h:

...

IBOutlet id hogeOutlet

...

HogeClass.m:

- (id)init

{

self = [super init];

if (self) {

// load nib

[NSBundle loadNibNamed:@"Hoge" owner:self];

}

return self;

}

と記載

(3)From another class, call HogeClass and its nib like this:

HogeClass* hogeInstance = [[HogeClass alloc] init];

とする。hogeInstanceを介してhogeOutletにアクセスできる。

Use Finder alias in Cococa

Even link type filewrapper cannot handle finder alias.

To handle alias in Cocoa, using Nathan Day's NDAlias is easy.

Subcalssing text storage/NSTextStorageのサブクラスを作る

Tue, 14 Aug 2007 20:48:03 +1200

NSTextStorageをサブクラス化するには、以下のようなメソッドを追加しておく必要がある。

(www.cocoadev.comより)

//#####################

- (id)init {

self = [super init];

if (self) {

m_attributedString = [[NSMutableAttributedString alloc] init];

}

return self;

}

- (void)dealloc

{

[[NSNotificationCenter defaultCenter] removeObserver:self];

[m_attributedString release];

[super dealloc];

}

- (NSString *)string

{

return [m_attributedString string];

}

- (NSDictionary *)attributesAtIndex:(unsigned)index effectiveRange:(NSRangePointer)aRange

{

return [m_attributedString attributesAtIndex:index effectiveRange:aRange];

}

- (void)replaceCharactersInRange:(NSRange)range withString:(NSString *)str

{

[m_attributedString replaceCharactersInRange:range withString:str];

int lengthChange = [str length] - range.length;

[self edited:NSTextStorageEditedCharacters range:range changeInLength:lengthChange];

}

- (void)setAttributes:(NSDictionary *)attributes range:(NSRange)range

{

[m_attributedString setAttributes:attributes range:range];

[self edited:NSTextStorageEditedAttributes range:range changeInLength:0];

}

NSWindow (無反応なウィンドウ window that is transparent to mouse -- ignore mouse action)

Tue, 14 Aug 2007 20:47:22 +1200

	[aWindow setIgnoresMouseEvents:YES];

NSWindow (Open Multiple Sub Windows using seperate nib file)

Tue, 14 Aug 2007 20:46:59 +1200

Open Multiple Sub Windows

(1) create document based NIB file and connect properly as shown below.

(SubWindowController is a sub-class of NSObject. Initiate and make file of it.)

Connect owner to window

Connect window to controller

(2) Coding

To open,

	NSWindowController* wc =

	[[NSWindowController alloc] initWithWindowNibName:@"NIBFilenameHere(without.nib)"];

	NSWindow* aWindow = [wc window];

	[wc showWindow:self];

When window is opened, subWindowController instance is made.

Methods can be implemented in "SubWindowController.m"

#import "SubWindowController.h"

@implementation SubWindowController

- (void)windowDidBecomeKey:(NSNotification *)aNotification

- (void)windowDidExpose:(NSNotification *)aNotification

@end

to stop timer,

 [aTimer invalidate];

NSTableView (Drag&drop)

NSString (Search in NSString)

Tue, 14 Aug 2007 20:45:27 +1200

NSRange aRange = [aString rangeOfString:aKey];

//result is stored in aRange

NSScrollView (Enable resizeing NSView in NSScrollView)

Tue, 14 Aug 2007 20:45:11 +1200

//config textView

	[aView setHorizontallyResizable:YES];

	[aView setVerticallyResizable:YES];

NSRect

Tue, 14 Aug 2007 20:44:38 +1200

NSRectを最初に宣言するときに

NSRect rect = NSZeroRect;

のように何かを入れておく。

何故かはわからないけど、そうしないと、その後の動作がおかしくなる場合がある。

×NG

NSRect rect;

...

rect = anotherRect;

NSLock

Tue, 14 Aug 2007 20:43:04 +1200

NSLock* lock;

[lock lock]; から、ロックを取得　※取得できるまで待つ

〜この中にロックで保護されるコードを書く。

[lock unlock];　で解除。

別のスレッドでも同様。

なお、

@synchronized(オブジェクト)

{

// ここに書かれたコードは、当該オブジェクトについて一度に一つのスレッドでしか実行されない。

//オブジェクト＝self など

}

NSFileWrapper

Tue, 14 Aug 2007 20:42:44 +1200

How to create directory file wrapper

//ファイルラッパの作成

NSFileWrapper *wrapper = [[[NSFileWrapper alloc] initDirectoryWithFileWrappers:NULL ] autorelease];

//データを追加する

[wrapper addFileWrapper:aWrapper ];

[wrapper addFileWrapper:anotherWrapper ];

[wrapper addRegularFileWithContents:aData preferredFilename:@"aData"];

How to decode file wrapper

NSDictionary* aDic = [wrapper fileWrappers];

NSFileWrapper* aWrapper;

NSFileWrapper* anotherWrapper;

aWrapper = [aDic objectForKey:@"aWrapper's name.rtfd"];

anotherWrapper = [aDic objectForKey:@"anotherWrapper's name.rtfd"];

data1 = [aWrapper serializedRepresentation];

data2 = [anotherWrapper serializedRepresentation];

data3 = [[aDic objectForKey:@"aData"] regularFileContents];

NSDocument, NSSavePanel

Tue, 14 Aug 2007 20:42:21 +1200

EXAMPLE - normal

- (NSData*)dataRepresentationOfType:(NSString*)type

	NSData* mySavingData;

	NSRange mySavingRange;

	mySavingRange.location = 0;

	mySavingRange.length =  [[htmlSource textStorage] length];

	mySavingData = [htmlSource RTFFromRange:mySavingRange];

    // Create data from stirng with encoding

    return mySavingData;

この関数は保存の際に勝手に呼び出される。

NSTextView ---> NSStorage に変換し、NSStorageのlengthメソッドでlengthを取り出している。

EXAMPLE - using file wrapper

ファイルラッパを使った保存

- (NSFileWrapper *)fileWrapperRepresentationOfType:(NSString*)type

	NSData* mySavingData;

	NSRange mySavingRange;

	mySavingRange.location = 0;

	mySavingRange.length =  [[htmlSource textStorage] length];

	mySavingData = [htmlSource RTFDFromRange:mySavingRange];

	NSFileWrapper *wrapper = [[htmlSource textStorage] RTFDFileWrapperFromRange:mySavingRange documentAttributes:(NSDictionary *)NULL];

    // Create data from stirng with encoding

    return wrapper;

Convert NSData to NSString or vise versa

Tue, 14 Aug 2007 20:41:57 +1200

	NSString* aStr;

	aStr = [[NSString alloc] initWithData:aData encoding:NSASCIIStringEncoding];

	NSData* aData;

	aData = [aStr dataUsingEncoding: NSASCIIStringEncoding];

NSSavePanel (opening save dialogue)

		myArray = [NSArray arrayWithObjects:myTableView1Data_A, myTableView1Data_B, NULL];

		[myArray writeToFile:[aPanel filename] atomically:YES];
