ios - Asynchronous image loading in a uitableview -

-

i'm integrating facebook in application , i'm @ point i'm loading profile pictures of friends of loggedin user. i'm presenting these users in uitableview, in each cell picture , name of friend. i've subclassed uiimageview , when corresponding cell handled in cellforview method, image loaded asynchronously.

however, when scroll , down several times, image flickering, first wrong pictures loaded, displayed short time , right image loaded. think have way stop loading of image when cell outside view.

is there can me problem , give me solution?

thanks in advance!

you consider not reusing cells. could, however, impair performance if have lot of table cells need loaded (e.g., lot of friends). since every cell has own image, flickering won't occur because of cell reusing.

another thing @ file size of images. chances they're bigger size you're showing them at. if there's way smaller version, help, too.

third, can set image view default image in tableview:willdisplaycell:forrowatindexpath. flickering still occur, default image, looks better if it's else's picture. in fact, think facebook app does.

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...
