objective c - iOS Simulator Not Recognizing Gestures -


i adding uiswipegesturerecognizer , uitapgesturerecognizer view in view controller's viewdidload method.

- (void)viewdidload {         [super viewdidload];         [self.view addgesturerecognizer:[[uiswipegesturerecognizer alloc] initwithtarget:self action:@selector(cardswipe:)]];         [self.view addgesturerecognizer:[[uitapgesturerecognizer alloc] initwithtarget:self action:@selector(cardtap:)]];     } - (void)cardswipe:(uiswipegesturerecognizer *)sender {     //get card. set faceup false.     cgpoint location =  [sender locationinview:sender.view];     nsindexpath *cellindex = [self.cardcollectionview indexpathforitematpoint:location];     if(cellindex){         uicollectionviewcell *cell = [self collectionview:self.cardcollectionview cellforitematindexpath:cellindex];         if(cell && [cell iskindofclass:[cardcollectionviewcell class]]){             [[((cardcollectionviewcell *)cell) cardview] handlecardswipe];         }     } } - (void)cardtap:(uitapgesturerecognizer *)sender {     //get card. set faceup false.     cgpoint location =  [sender locationinview:sender.view];     nsindexpath *cellindex = [self.cardcollectionview indexpathforitematpoint:location];     if(cellindex){         uicollectionviewcell *cell = [self collectionview:self.cardcollectionview cellforitematindexpath:cellindex];         if(cell && [cell iskindofclass:[cardcollectionviewcell class]]){             [[((cardcollectionviewcell *)cell) cardview] handlecardswipe];         }     } }

in case relevant: view contains uicollectionview.

the taps , swipes not getting recognized. there obvious missing? thanks.

turns out view not responding gestures - scrolling, taps on buttons or swipe actions. deleted generated folders ~/library/application support/iphone simulator / 6.1/applications , ~/library/developer/xcode/deriveddata, reset simulator settings (from ios simulator > reset contents , settings), did clean in xcode (product > clean) , ran app again. gestures recognized. not sure of above fixed problem...it possible resetting simulator's contents , settings have been enough.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
