iphone - How to read a random line from a textfile? -

-

i'm absolute beginner xcode , objective-c, hey sounded book i'm reading rory lewis ! i'm trying write simple question game ios.

this first app, except few versions "hello world" ;-) have read large number of forums, , haven't yet found i'm looking for.

so read out random line plain textfile, let's "file.txt" wich contains 500 lines. when press button, app fetch random line file.txt , present on screen. have tried number things, , feel i'm fumbling in dark ! hoping point me in right direction (a basic 1 please ;-).

something should work:

#include <stdlib.h> #include <time.h>  nsstring *file = [[nsbundle mainbundle] pathforresource:@"file" oftype:@"txt"];  nsstring *filecontents = [nsstring stringwithcontentsoffile:file];  nsarray *lines = [filecontents componentsseparatedbystring:@"\n"];   /* initialize random seed: */   srand ( time(null) );    /* generate random number: */   int index = rand() % [lines count];  nsstring *string = [lines objectatindex:index];

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.
