从Obj-C内部调用静态Swift方法

// SwiftClass.h

#import <Foundation/Foundation.h>

@class SwiftClass;

@interface SwiftClassWrapper : NSObject

+ (void)callStaticMethod;

@end

// SwiftClassWrapper.m

#import "ProjectName-Swift.h"
#import "SwiftClassWrapper.h"

@implementation SwiftClassWrapper

+ (void)callStaticMethod {
    [SwiftClass staticMethod];
}

@end

// SwiftClass.swift

import Foundation

@objc public class SwiftClass: NSObject {
    
    @objc public static func staticMethod() {
        // 静态方法的实现
    }
    
}

// ObjectiveCClass.m

#import "ProjectName-Swift.h"
#import "SwiftClassWrapper.h"

@implementation ObjectiveCClass

- (void)callSwiftStaticMethod {
    [SwiftClassWrapper callStaticMethod];
}

@end
