iphone - Weird behavior of hidesBottomBarWhenPushed = YES (moves views when popping back) -

-

so i've got weird going on here, , can't quite put figure on it. basically, i've got view has 2 subviews: 1 webview, other button controller

see here bug: http://screencast.com/t/ztjaup8axgz

now when pushviewcontroller controller , pop back, works fine, except when pushviewcontroller view controller (the 1 magnifying glass). when that, see following bugs:

  1. the webview gets 20 pixels shorter
  2. the button controller gets pushed 7-8 pixels.

i've isolated down fact when tab bar hidden (with hidesbottombarwhenpushed = yes), bug no longer seen:

http://screencast.com/t/vargpr4u

what cause this? bug in hidesbottombarwhenpushed ? if so, how can compensate it?

with little bit of debugging, ended finding out subview in question growing 10 px, being shifted -5.

i wasn't updating height of view anywhere - coworker suggested turn off autoresizessubviews (which did in nib of parent controller). fixed issue.

presumably, parent (containing) controller's view bounds had changed, although saw no evidence of in debugger.

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.
