Memory problem in NSXMLParser (iPhone) -

-

hi i'm trying parse xml , use currentelementvalue inside code expiredate. code.

if([elementname isequaltostring:@"utlop"]) {     nsdate *now = [nsdate datewithtimeintervalsincenow:0];     nsdateformatter *dateformat = [[nsdateformatter alloc] init];     [dateformat setdatestyle:nsdateformattershortstyle];     int numberofdays = [currentelementvalue intvalue];     nsdate *expiredate = [now addtimeinterval:60*60*24*numberofdays];     nsstring *expirestring = [dateformat stringfromdate:expiredate];     nslog(@"expirystring :%@", expirestring);        //add values vare     envare.utlop = expirestring;     envare.enhet = enhet;     envare.isdirty = no;      //add vare     [appdelegate addvare:envare];       //releasing     [dateformat release];     [envare release];     envare = nil;     [currentelementvalue release];     currentelementvalue = nil;     [expirestring release];     expirestring = nil;

this results in memory leak, im new objective c can't find error. when this, works:

 envare.utlop = currentelementvalue;

do not release objects not owned you. own object when u create them using new or alloc. release objects created using these functions. make sure release such objects once have finished using them.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
