ios - UICollectionView cell.ViewWithTag returning nil for UILabel -

-

this label seems return nil, though have reuseidentifier , tag set properly. 

override func collectionview(collectionview: uicollectionview, cellforitematindexpath indexpath: nsindexpath) -> uicollectionviewcell {     var identifier: string = "collectioncell"     var cell: uicollectionviewcell = collectionview.dequeuereusablecellwithreuseidentifier(identifier, forindexpath: indexpath) as! uicollectionviewcell      // configure cell       //save till later, when images present      //var cellitem1 = hostmanager[indexpath.row * 2]      let label:uilabel = cell.viewwithtag(1) as! uilabel     return cell  }

the program breaks label set = viewwithtag. have no custom class set cell, prototype. tag set on storyboard. getting error "exc_bad_instruction...". appreciated, thanks!

try removing line viewdidload:

self.collectionview!.registerclass(uicollectionviewcell.self, forcellwithreuseidentifier: reuseidentifier)

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
