ios - Why set retain on @property for subviews? -

fairly straightforward question in 2 parts.

if view retains subviews, , create view hierarchy in interface builder views nested within others, why iboutlet property nested subviews need set retain? wouldn't assign acceptable parameter subview properties?

i have uiview subclass adds few subviews upon initialization. capture references specific subviews, @property (nonatomic, assign) suffice need, correct? example, main uiview adds player score subview, later wants talk player score update it. reference needs assigned, view proper automatically retain uiview class, right?

1) doesn't need be. assign fine. made think have utilize retain?

2) yes

by way, using arc? if so, utilize weak instead of assign (please don't inquire why, explained in every corner of stack overflow , net in general).

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...
