uiviewcontroller - Crash when Adding a WebView to a Multiview Tab Bar App -

-

i new , working thru "teach book". have 2 questions. how trouble-shoot in future , how darn thing work now.

i have simple 3 tab bar app points 3 uiviewcontroller. 3 views work fine until add webview 1 of xibs. bring view webview included in simulator, kicked out of app.

the debugger console says"'nsunknownkeyexception', reason: '[ setvalue:forundefinedkey:]: class not key value coding-compliant key bannerview.'" don't know means.

.h file code....

@interface convnavcontroller : uiviewcontroller { iboutlet uiwebview *bannerview; } -(ibaction)loadbannerview:(id)sender;

@property (nonatomic, retain)iboutlet uiwebview *bannerview;

========= .m file code -(ibaction)loadbannerview:(id)sender{

nsurl *bannerurl;  nsstring *bannerurlstring;  bannerurlstring=[[nsstring alloc] initwithstring:@"http://www.tak2000.com/banner_test.html"]; bannerurl =[[nsurl alloc] initwithstring:bannerurlstring];   [bannerview loadrequest:[nsurlrequest requestwithurl:bannerurl]];     [bannerurl release]; [bannerurlstring release];

}

i used simple button connected loadbannerview.

webview code worked great in simple 1 view example. why dying when use in multi uiviewcontroller app? btw: used "windows based app" template starting point. ensured class identity uiwebview.

thanks in advance...

bannerview property, should be

[self.bannerview loadrequest ....]

and make sure in interface builder you've connected uiwebview bannerview outlet.

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.
