ios - How to read the response headers every time using AFNetworking? -

-

while using 3rd party api, have requirement cancel traffic when custom response header set value. trying find nice place check once in code (and not in every success/failure block, works fine). understand, done overriding -(void)enqueuehttprequestoperation:(afhttprequestoperation *)operation in custom afhttpclient subclass, when implement that:

-(void)enqueuehttprequestoperation:(afhttprequestoperation *)operation {     nslog(@"[request url]\n%@\n", [operation.request.url description]);     nslog(@"[response headers]\n%@\n", [[operation.response allheaderfields] descriptioninstringsfileformat]);      [super enqueuehttprequestoperation:operation]; }

the response headers nil. can me that?

at moment when operations being created , enqueued in afhttpclient, not have response server--that assigned when request operation executed.

although requirement cancel traffic seems unorthodox (at least if outside of conventions of http), easy accomplish:

in afhttpclient subclass, add bool property stores if requests should prevented, , used in enqueuehttprequestoperation. then, override httprequestoperationwithrequest:success:failure: execute specified success block along logic set aforementioned property if salient response present.

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...
