Display Contents of PDF opened in iOS App (Swift) -

-

i have app configured pdfs in other applications such mail, can hold down on pdf , have open "open in" app; have working , app opens, want display document in app, how do that? pretty sure have use appdelegate, started using swift , lost , cannot find tutorial helps task, appreciated.

appdelegate.swift

class appdelegate: uiresponder, uiapplicationdelegate {

var window: uiwindow? let uiapplicationlaunchoptionsurlkey: string = ""  func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {     if uiapplicationlaunchoptionsurlkey.isempty {         print("string empty.")     }     else{      let alertview:uialertview = uialertview()     alertview.title = "pdf upload"     alertview.message = "??"     alertview.delegate = self     alertview.addbuttonwithtitle("ok")     alertview.show()     }     return true }

in appdelegate's didfinishlaunchingwithoptions, can handle setting ui display pdf. can use uiwebview render document.

iphone : can open pdf file using uiwebview?

edit:

this link explains launch options can listen in appdelegate. didfinishlaunchingwithoptions. uiapplicationlaunchoptionsurlkey contain url pointing file.

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/...
