python - Show That User Is Logged Into iOS app -



python - Show That User Is Logged Into iOS app -

the login works backend , goes home screen after login on ios. how do guarantee user beingness logged in?

for example, have label user's username displayed in, don't know how user's username .

i have thought can phone call server , homecoming username in json format, isn't kind of inefficient? improve way this?

ps. first time ios programmer

additional info: using flask , flask-login extension backend. using login_user(user) method. has worked in past web dev, how work ios dev.

@app.route('/login/', methods=['post']) def login(): params = json.loads(request.data) username = params['username'] password = params['password'] u = user.query.filter_by(username=username).first() if u: if utils.check_password_hash(password, u.pw_hash): login_user(u) homecoming ('', 200) else: homecoming ('', 400) else: homecoming ('', 400)

take @ parse.com's ios sdk (https://www.parse.com/docs/ios_guide#top/ios). provides login form ability utilize pfuser object determine if user logged in or not. best thing parse it's free. :)

calling [pfuser currentuser] homecoming user that's logged in or nil if there no user.

python ios flask flask-login

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
