Change this
改变这个
-(void)GetCountries:(id)sender detailDictionary:(id)details
{
{
}
}
To
到
+(void)GetCountries:(id)sender detailDictionary:(id)details
{
{
}
}
And then to call it in another class simply do
然后在另一个类中调用它简单地做
[JewelsSharedController GetCountries];
What we are doing is creating a class function, what that means is you can call the function directly on the class without having to initialize an instance of the class first.
我们正在做的是创建一个类函数，这意味着您可以直接在类上调用该函数，而无需先初始化类的实例。
