UIView の階層を lldb の print-object で見てみた

xcode lldb

iPhone の画面に張り付いている UIView の階層をコマンド一つで確認できるなんて知らなかった…。
こんな感じ。

(lldb) po [[self view] recursiveDescription]
(id) $1 = 0x0945f030 <UIView: 0x8777ac0; frame = (0 0; 320 411); autoresize = W+H; layer = <CALayer: 0x8777bd0>>
   | <UIButton: 0x9450b80; frame = (25 63; 270 113); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x9450c10>>
   |    | <UIImageView: 0xcd68790; frame = (0 0; 270 113); clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0xcd6b060>>
   |    | <UIButtonLabel: 0x8779da0; frame = (270 47; 0 19); text = 'Sleep'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0x8752c20>>
   | <UIImageView: 0x8774700; frame = (0 0; 320 56); autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x8776780>>
   | <UIButton: 0x944efb0; frame = (25 186; 270 113); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x944f070>>
   |    | <UIImageView: 0xcd714d0; frame = (0 0; 270 113); clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0xcd71510>>
   |    | <UIButtonLabel: 0x9450670; frame = (0 0; 0 0); clipsToBounds = YES; hidden = YES; opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0x9450740>>
   | <UILabel: 0x87779d0; frame = (25 336; 270 21); text = ''; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x8777a40>>
   | <UILabel: 0x877a5d0; frame = (25 307; 270 21); text = ''; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x877a110>>
   | <UIView: 0x92536a0; frame = (100 146; 120 120); clipsToBounds = YES; alpha = 0.3; hidden = YES; tag = 10001; layer = <CALayer: 0x9254b60>>
   | <UIActivityIndicatorView: 0x9251b90; frame = (141 187; 37 37); hidden = YES; tag = 10002; layer = <CALayer: 0x92505c0>>
   |    | <UIImageView: 0x9274da0; frame = (0 0; 37 37); opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0x9254cc0>>
   | <UIImageView: 0x87774e0; frame = (0 411; 320 50); autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x87769c0>>
(lldb)

で、この画面はこんな画面。

@interface MainViewController : UIViewController <UIGestureRecognizerDelegate> {    
	UIButton *sButton;
	UIButton *gButton;
	UILabel *messageLabel;
	UILabel *messageLabel2;
	UIImageView *bannerImageView;
	UIImageView *bottomBannerImageView;
}

あ、UIActivityIndicatorView はここに出てないけどコードの中で作って貼り付けてある。


というわけで、lldb で po する時って objective-c のコードを入力できるのが面白いな〜。
