我创建了一个 Swift 框架，它以编程方式创建一个按钮，按钮的操作显示一个 webView 并关闭它，我的框架在 Swift 项目中工作正常，但在 Objective C 中它只是创建按钮，但它没有采取行动，也没有显示我的 webView，注意：我使用 SwiftyJSON 通过 JSON 从服务器获取按钮配置
下面是框架项目中除了 SwiftyJSON 之外的我的 Swift 类

我创建了一个 Objective-C 并在其中添加了构建的框架，它的 .m 文件代码如下：
#import "ViewController.h"
@import myFrameWork;
#import <myFrameWork/myFrameWork-Swift.h>
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
predictionButton *btn = [[predictionButton alloc] init];
[btn addButtonPredictWithView:self.view phone:@"XXXXXXX"
token:@"XXXXXXXXXXXXXXXXXXXXXXXXXXX"];
}
@end
注意：这个框架在 Swift 项目中运行良好
这是工作快速代码：
import UIKit
import myFrameWork
import WebKit
class ViewController: UIViewController {
var button = predictionButton()
override func viewDidLoad() {
super.viewDidLoad()
button.addButtonPredict(view: self.view, phone: "XXXXXXXXXX", token: "XXXXXXXXXXXXXXXXXXXXXXXXX")
}
