uisplitviewcontroller - iPad UISplitView Detail Toolbar NULL on Startup -

-

i've been racking brain trying figure out little bug in ipad half of app i'm working on. it's related problem in post:

ipad splitviewcontroller strange behaviour

actually, should it's same problem. however, solution given there won't work me, since app has main menu swaps on uisplitviewcontroller's view when proper button pressed. controller , contained view controllers aren't created until button press. thus, can't set controller's delegate before calling [window makekeyandvisible], since that's done way when main menu loads.

now, i've added nslog calls delegate's willhideviewcontroller function follows:

nslog(@"will hide popover view controller!"); nslog(@"self=%p",self); nslog(@"%@",detailpad.tbtoolbar);

when start app on ipad in portrait mode, , click switch on split view controller, delegate's willhideviewcontroller indeed called, when finishes, i'm left empty toolbar in detail view. strange part that third nslog call, should output info detail view controller's toolbar, spits out (null) instead. made stranger fact preceding code sets toolbar's items, , code doesn't cause single exception raised, though toolbar apparently doesn't exist.

as can see, subsequent logs show toolbar alive , well, , know calls coming same object in cases. these later calls came rotating landscape , portrait, it's same detail view controller well.

so question this: cause toolbar come null first time, work after doing nothing rotating ipad, , can fix it?

thanks in advance, ryan

and... found workaround. had master view controller set split view controller's delegate, fine. however, first time willhideviewcontroller called happens before detail view has been set up; that's why toolbar doesn't exist yet. moved several things on detail controller, , made delegate instead. then, in addition setting toolbar's items in willhideviewcontroller, set them in viewdidload. detail view controller hands popover button , controller master view controller, since master needs able create new detail view controllers , assign them popover button (i neglected mention before detail view controllers pushed , popped navigation controller).

it ain't pretty, works.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
