swift - iOS Parse notification with custom radius geopoint from key -

-

i have huge problem parse ios , geo-query push notifications. want schematically. class "helplocationlistener"

| location | radius | user |

| xxx | 2 | usera |

| xxy | 5 | userb |

| xyy | 2.5 | userc |

when user sends "help" geo-located, other users should notified if "help" within area calculated | location | , | radius | if coordinates of "help" contained in area date xxx radius 2, user usera receive push notification.

absurdly need this: userquery.wherekey ("location", neargeopoint: "help", withinmiles "radius")

i searched hours not find answer, if not possible application not make sense exist. seems impossible possibility has not been provided.

i'm using swift lang.

i ask sincere help! (sorry english)

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/
