		"description": "Hi,\r\n\r\nLots of problem with remove method. Didn't find any function to clear all children.\r\nCreate a simple scrollView (i guess it's the same for views), add some ImageViews inside and try :\r\n\r\n{code}\r\nvar simpleView = Ti.UI.createView({\r\n\t\t\tid : 'mainView',\r\n\t\t\ttop : 0,\r\n\t\t\tleft : 0,\r\n\t\t\tlayout : 'absolute',\r\n\t\t\twidth : Ti.Platform.displayCaps.platformWidth,\r\n\t\t\theight : Ti.Platform.displayCaps.platformHeight\r\n\t\t});\r\n{code}\r\nor\r\n{code}\r\nvar simpleView == Ti.UI.createScrollView({\r\n\t\t\ttop : 0,\r\n\t\t\tzoomScale : 1,\r\n\t\t\tminZoomScale : 1,\r\n\t\t\tmaxZoomScale : 2,\r\n\t\t\twidth : Ti.Platform.displayCaps.platformWidth,\r\n\t\t\theight : Ti.Platform.displayCaps.platformHeight,\r\n\t\t\tcontentWidth : 'auto',\r\n\t\t\tcontentHeight : 'auto'\r\n}\r\n{code}\r\n\r\nthen ...\r\n\r\n{code}\r\nvar images = [];\r\n\r\nfor(var i=0; i < 10; i++){\r\n         images.push(Ti.UI.createImageView({\r\n\t\t\t\t\timage : 'image' + i + '.jpg',\r\n\t\t\t\t\twidth : 600,\r\n\t\t\t\t\theight : 400,\r\n\t\t\t\t\tleft : 0,\r\n\t\t\t\t\ttop : 0\r\n\t\t\t\t}));\r\n}\r\n\r\nfor(var i=0; i<imgs.length; i++){\r\n    simpleView.add(images[i]);\r\n}\r\n\r\n\r\nvar removeChildren = function(view){\r\n\twhile(view.children != undefined){\r\n\t\tview.remove(view.children[0]);\r\n\t}\r\n}\r\n\r\nremoveChildren(simpleView);\r\n{code}\r\n\r\nGetting sometimes : \r\n{code}\"*** -[__NSArrayM objectAtIndex:]: index N beyond bounds [0 .. X]\";{code}\r\nat this line :\r\n{code}while(view.children != undefined){code}\r\n\r\nI tried other ways to do removeChildren method but none works well on titanium mobile 1.8.1.0 ( http://developer.appcelerator.com/question/131151/emptying-a-view#228486 )\r\n\r\n********************\r\n\r\nAnother method is the following : \r\n{code}\r\nvar removeAllChildren = function(viewObject) {\r\n\tif(viewObject.children != undefined){\r\n\t\tvar children = viewObject.children.slice(0);\r\n\t\t\r\n\t\tfor(var i = 0; i < children.length; i++) {\r\n\t\t\ttry {\r\n\t\t\t\tviewObject.remove(children[i]);\r\n\t\t\t} catch(e) {\r\n\t\t\t\tTi.API.error('removeAllChildren error : ' + e.message + ' ' + viewObject);\r\n\t\t\t}\r\n\t\t}\r\n\t\tchildren = null;\r\n\t}\r\n}\r\n{code}\r\n\r\nbut there's a warning on each remove invocation (in my case it's a scrollView instead of a view but i guess it's the same pb) :\r\n\r\n{code}\r\ncalled remove for [object TiUIImageView] on [object TiUIScrollView], but [object TiUIImageView] isn't a child or has already been removed\r\n{code}\r\n\r\nand sometimes i get\r\n{code}\"Result of expression 'viewObject.children' [undefined] is not an object.\";{code}\r\nfor line\r\n{code}if(viewObject.children != undefined){code}\r\n\r\n********************\r\n\r\n- In general it's hard to loop through children of a view an to remove some children. This kind of way to do return sometimes an error :\r\n\r\n{code}\r\nfor(var i=0; i< simpleView.children.length; i++){\r\n\tif(XXXXX){\r\n\t\tsimpleView.remove(player.ui.mainView.children[i]);\r\n\t\ti--;\r\n        }\r\n}\r\n{code}\r\n\r\nat line {code}for(var i=0; i< simpleView.children.length; i++){code} it launch sometimes this exception\r\n{code}\"*** -[__NSArrayM objectAtIndex:]: index X beyond bounds [0 .. X]\";{code}\r\n\r\n\r\n\r\nBest Regards\r\n",
