Printing Ivars
Often just typing *varName works:
cy# *controller
{isa:"PrefsRootController",_contentView:"<UIView: 0x10bd70; frame = (0 0; 320 460); autoresize = W+H; layer = <CALayer: 0x150120>>",_navBar:"<UINavigationBar: 0x150d40; frame = (0 0; 320 44); autoresize = W; layer = <CALayer: 0x150e00>>",_controllers:["<PrefsListController 0x1525e0: title Settings, view <UIPreferencesTable: 0x1529d0; frame = (0 0; 320 416); clipsToBounds = YES; autoresize = H; layer = <CALayer: 0x152c00>>>"],_title:"Settings",_idStr:"com.apple.preferences.settings",_size:{width:320,height:416},_navBarRightButtonTitle:null,_navBarRightButtonStyle:0,_navBarRightButtonDirty:0,_tasks:"{(\n)}",_deallocating:0,_hasTelephony:1,_togglingAirplaneMode:0,_airplaneMode:"Airplane Mode\t\tID:Airplane Mode 0x15b600",_airplaneSheet:null,_airplaneSheetTarget:null,_airplaneSheetAction:null,_numberOfInstalledApps:61}
cy#
Sometimes it doesnt...
cy# *UIApp
{message:"hasProperty callback returned true for a property that doesn't exist.",name:"ReferenceError"}
then you can do:
cy# a = []; for (i in *UIApp) a.push(i); a ["isa","_delegate","_touchMap","_exclusiveTouchWindows","_event","_touchesEvent","_motionEvent","_topLevelNibObjects","_orientation","_networkResourcesCurrentlyLoadingCount","_hideNetworkActivityIndicatorTimer","_editAlertView","_applicationFlags","_controller","_window","_isLocked","_settingTimeZone","_busyControllers"]
