ios - NSPredicate ANY with multiple columns -

-

I have 2 tables, person and social

There are multiple societies in person; Usernames and services in Social

I am trying to write a bill on the person table which will match with the appropriate username and service from the social table. The statement below is incorrect Please let me know whether to use the same syntax or if there is a better way to get it. [AddObject predicts: [NSPredicate predicateWithFormat: @ "Anyone (Social usernames =% @ and socials.service =% @)", @ "Username", @ " Service "]];

This is a special use case for SUBQUERY:

< Pre> [NSPredicate predicateWithFormat: @ "SUBQUERY (social, $ s, $ s.username =% @ AND $ s.service =% @). @ Calculation> 0", @ "user name", @ "Service"]

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
