[iPhone]UIDatePickerのメモ（自分用）

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
CGRect frameForWindow = [[UIScreen mainScreen] bounds];
_window = [[UIWindow alloc] initWithFrame:frameForWindow];

//アプリのウインドウと同じサイズの四角形を取得
CGRect rect = CGRectMake(0.0, 20.0, 320.0, 460.0);

//上記で取得したサイズのピッカーを作成
picker_ = [[UIDatePicker alloc] initWithFrame:rect];

NSDate *date = [NSDate date];

[picker_ setDate:date animated:NO];
[picker_ setMinimumDate:date];
[picker_ setMaximumDate:[NSDate dateWithTimeIntervalSinceNow:3600*24*365]];
[picker_ setCalendar:[NSCalendar currentCalendar]];
[picker_ setTimeZone:[NSTimeZone systemTimeZone]];

[_window addSubview:picker_];

// [picker release];


// 標準ボタン例文
btn_ = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn_.frame = CGRectMake(100, 300, 100, 30);
[btn_ setTitle:@"押してね" forState:UIControlStateNormal];
[btn_ setTitle:@"ぽち" forState:UIControlStateHighlighted];
[btn_ setTitle:@"押せません" forState:UIControlStateDisabled];
// ボタンがタッチダウンされた時にhogeメソッドを呼び出す
[btn_ addTarget:self action:@selector(pushBtn:)forControlEvents:UIControlEventTouchDown];
[_window addSubview:btn_];

// [btn release];

[_window makeKeyAndVisible];

return YES;
}
- (void)pushBtn:(UIButton*)button{
NSDateFormatter *inputDateFormatter = [[NSDateFormatter alloc] init];
[inputDateFormatter setDateFormat:@"yyyy/MM/dd HH:mm:ss"];
NSString *intputDateStr = @"2012/09/02 03:04:05";
[inputDateFormatter setTimeZone:[NSTimeZone systemTimeZone]];
[inputDateFormatter setCalendar:[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]];
NSDate *inputDate = [inputDateFormatter dateFromString:intputDateStr];

[inputDateFormatter release];

[picker_ setDate:inputDate animated:YES];

NSLog(@"picker_ => %@",[picker_ description]);
NSLog(@"picker_.date => %@",[picker_.date description]);
NSLog(@"picker_.minimumDate => %@",[picker_.minimumDate description]);
NSLog(@"picker_.maximumDate => %@",[picker_.maximumDate description]);
NSLog(@"picker_.calendar => %@",[picker_.calendar description]);
NSLog(@"picker_.timeZone => %@",[picker_.timeZone description]);
}

UIDataPickerのdateは本体のカレンダー設定にどうしても引きずられるようです。
それはどうしようもなさそう。。
設定するdateはフォマッタで文字列の与える文字列のフォーマットを
カレンダーとフォーマットストリングで指定してあげればよい。
