描画

  • UIViewのサブクラスを作成して
- (void)drawRect:(CGRect)rect {
    // Drawing code
    // グラフィックコンテキスト取得

    CGContextRef context = UIGraphicsGetCurrentContext();

    // CoreGraphicsの原点が左下なので原点を合わせる
    CGContextTranslateCTM(context, 0, rect.size.height);
    CGContextScaleCTM(context, 1.0, -1.0);

    // 線の色を R,G,B,A で設定
    CGContextSetRGBStrokeColor(context, 0.0, 1.0, 0.0, 1.0);
    // 線の太さ
    CGContextSetLineWidth(context, 10);

    // Pathを作成
    CGContextBeginPath(context);
    // Pathの位置設定
    CGContextMoveToPoint(context, 100.0, 100.0);
    CGContextAddLineToPoint(context, 50.0, 150.0);
    CGContextAddLineToPoint(context, 100.0, 150.0);
    // Pathの描画
    CGContextDrawPath(context, kCGPathStroke);

    NSString* str = [NSString stringWithFormat:@"Elapsed time: %f", -elapsedTime]; 
    UIFont *font = [UIFont systemFontOfSize:24];
    [[UIColor whiteColor] set];//色
    [str drawAtPoint:CGPointMake(0,0) withFont:font];
}
  • UIGraphicsGetCurrentContext?
  • CGContextRef?

メモ

  • 概念上は、iPhone OSのウインドウとビューは、Mac OS Xの場合と同様に同じ構成体を表しています。しかし、実装の観点では、この2つのプラットフォームはウインドウとビューをまったく異なった方法で実装しています。Mac OS Xでは、NSWindowクラスはNSResponderのサブクラスですが、iPhone OSでは、UIWindowクラスは実際はUIViewのサブクラスです。この継承関係の違いは、ウインドウがCore Animationレイヤを使用して描画サーフェスを実現していることを意味します。UIKitのすべてでウインドウオブジェクトを持つ理由は、オペレーティングシステム内でウインドウのレイヤ化をサポートするためです。
