[iPhone]全局变量 [英] [iPhone] Global Variables

问题描述

大家好，

有谁能告诉我如何定义可以在整个应用程序中开始使用的全局变量?

目前，我已经尝试过，但是，它显然给我抛出了错误.. ::

http://plaatscode.be/141545/
http://plaatscode.be/141543/

第二个网址的第7、8、9行出现错误:
-从不兼容的类型"id"分配给"NSString"
-从不兼容的类型"id"分配给"NSString"
-从不兼容的类型数据库* __ strong"分配给数据库"

另一种选择是将这些值直接传递给状态机.

Hi everyone,

Is there anyone who could tell me how i could define global variables which I could start using in my entire application?

currently I''ve tried, However, it is throwing me errors obviously..:

http://plaatscode.be/141545/
http://plaatscode.be/141543/

errors on lines 7,8,9 of the second url:
- Assigning to ''NSString'' from incompatible type ''id''
- Assigning to ''NSString'' from incompatible type ''id''
- Assigning to ''Database'' from incompatible type ''Database *__strong''

An alternative would be to pass these values directly to the statemachine.

LoginStateMachine *machine = [[LoginStateMachine alloc] init];
[machine Login];

有谁可以帮助我定义全局变量吗?

亲切的问候，
Lars

The first idea that came into mind was a singleton, and surprisingly it is also the preferred method. Check out this link for more info:
