ios - Using the UIDocumentPickerViewController, is it possible to show a default service (Dropbox, Google Drive, etc) on first open like in Slack? -

-

normally, behavior uidocumentpicker present, user must use "locations" menu on top right switch between services. possible display either "dropbox" or "google drive" first default? if we're "deeplinking" uidocumentpicker service.

it seems slack app able , mymail app wasn't able find api it. ideas?

slack app

instead of using uidocumentpickerviewcontroller, try using uidocumentmenuviewcontroller. here relevant documentation.

uidocumentmenuviewcontroller *documentprovidermenu = [[uidocumentmenuviewcontroller alloc] initwithdocumenttypes:[self utis]                                                      inmode:uidocumentpickermodeimport];  documentprovidermenu.delegate = self; [self presentviewcontroller:documentprovidermenu animated:yes completion:nil];

by default, display apps include document provider extension (such dropbox, google drive, icloud, etc.). if user has dropbox or google drive installed on device, these options show automatically.

you can add custom options menu calling addoptionwithtitle:image:order:handler: method.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
