ios - Does dismissViewControllerAnimated:completion: retain previous view controllers? -

-

i having memory leaks , crashes in app , know if due way container view controller switches between view controllers. app should allow user navigate long series of pages. each page laid out viewcontroller in storyboard (each page has number identifier).

by time page 14 in app, can see in instruments' activity monitor app takes 600mb of memory (on ipad 3). because each view controllers have uiimageviews big images.

i using arc.

below code container view controller. can see memory management problem somewhere?

@implementation pagenavigator  int startingpage = 0; int currentpage = 0;  -(void)viewdidappear:(bool)animated{     nslog(@"starting book page %d", startingpage);      //do first time app runs     if(startingpage != -1){         uiviewcontroller *currentpagevc = [self.storyboard instantiateviewcontrollerwithidentifier:[nsstring stringwithformat:@"%d", startingpage]];         [self presentmodalviewcontroller:currentpagevc animated:yes];         currentpage = startingpage;         startingpage = -1;     } }  //currentpagevc , outlets should released when gets out of scope, right?  -(ibaction)gotonextpage{     [self dismissviewcontrolleranimated:yes completion:^{          currentpage++;         uiviewcontroller *currentpagevc = [self.storyboard instantiateviewcontrollerwithidentifier:[nsstring stringwithformat:@"%d", currentpage ]];         [self presentmodalviewcontroller:currentpagevc animated:yes];          nslog(@"current page %d", currentpage);      }]; }

when dismissviewcontrolleranimated called control goes dealloc method of controller, if not using arc , allocating memory ui controls need release those, , won't need take care of view controller's memory.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
