使用Objective c在后台调用类方法

Question

在下面的摘录中,

/*A ClassName with instanceMethod and ClassMethod  */

-(void)instanceMethod;

+(void)ClassMethod;

/*To call a instance method in background */

ClassName  class1obj = [ClassName alloc] init];

[class1obj performSelectorInBackground:@selector(instanceMethod) withObject:nil];

同样,如何使用后台调用ClassMethod performSelectorInBackground？

如果可能,请解释!请伙计们携手..

Answer 1

打电话吧

[ClassName performSelectorInBackground:@selector(ClassMethod) withObject:nil];

因为类本身就是对象,所以这将起作用.
