如何使用 objc_class 變量調用類方法

Question

@interface SomeClass
- (void)funcA;
+ (void)funcB;
@end

@interface Test
@property(nonatomic, assign) Class aClass;
@end

@implementation Test
- (void) test {
    // that's ok
    [[aClass new] funcA];
    // but how to call class method?
    [aClass funcB] ?
}
@end

XCode 注釋“實例方法‘函數’被用於不在根類中的‘類’”

Answer 1

你有沒有嘗試過 ？

[[aClass class] performSelector:@selector(funcB)];

Answer 2

[((id)aClass) funcB];

或類似於@Pancho的回答

[[aClass class] funcB];
