ios - CloudKit fetchUserRecordIDWithCompletionHandler completion code not calling? -

-

i trying fetch current user id cloudkit using fetchuserrecordidwithcompletionhandler when run code, completion handler skipped over.

let container = ckcontainer.defaultcontainer() let publicdatabase = container.publicclouddatabase  var userid: ckrecordid!  container.fetchuserrecordidwithcompletionhandler( { recordid, error in     if error == nil {         userid = recordid      } else {         nslog("\(error.localizeddescription)")     } })   let predicate = nspredicate(format: "personid = \(userid)")  let query = ckquery(recordtype: "person", predicate: predicate)

because of this, value of userid stays nil, , query throws exception because of it.

the completion handler run once fetch request complete, happen asynchronously. cannot use result of fetch request after call. move query completion handler of other part of code can called or otherwise triggered handler.

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...
