Question

我在项目中添加了ful SDWebImage文件夹。还添加了一个桥接头。我的应用程序在安装过程中不会产生任何问题但是当我尝试访问SDWebImage方法时，它会给出以下异常“无法识别的选择器发送到实例”，错误代码为：

这是我的桥接头文件代码：

#ifndef Messenger_Bridging_Header_h
#define Messenger_Bridging_Header_h

#import <authsdk/AuthSDKManager.h>
#import <IMSDK/IMManager.h>
#import "OpenUDID.h"
#import "UIImageView+WebCache.h"
#import "OrderedDictionary.h"
#import "UINavigationController+SGProgress.h"
#import "KASlideShow.h"

#endif /* Messenger_Bridging_Header_h */

这是我在我的项目中使用SDWebImage方法的代码：

    func showImageFromURLString(urlString: String, in imageView: UIImageView, with activityIndicatorView: UIActivityIndicatorView) -> Void {
        let imageURL = URL(string: urlString)
        if let url = imageURL{
            activityIndicatorView.isHidden = false
            activityIndicatorView.startAnimating()

//          imageView.setImageWith(url, placeholderImage: nil, options: .cacheMemoryOnly){
//              (image, error, cacheType) in
//              activityIndicatorView.stopAnimating()
//              activityIndicatorView.isHidden = true
//          }
            imageView.sd_setImage(with: url, placeholderImage: nil, options: .cacheMemoryOnly) {
                (image, error, cacheType, url) in
                activityIndicatorView.stopAnimating()
                activityIndicatorView.isHidden = true
            }
        }
    }

Answer 1

原因：

从＆＃34; Build Phases - ＆gt;添加Link Binary with Libraries＆＃34;这补充说该框架并在该根文件夹中制作了该框架的副本这些项目。

解决方案：

使用Libraries从Link Binary中删除库，也从中删除 Project Navigator，然后复制＆＃34; AppName - ＆gt;下的框架文件。 AppName - ＆gt;框架＆＃34;，然后添加项目导航器，然后添加链接二进制文件与库

最后在项目桥接标题上添加此行，如下所示，问题应该解决

#ifndef Messenger_Bridging_Header_h
#define Messenger_Bridging_Header_h

#import <SDWebImage/UIImageView+WebCache.h>

#endif /* Messenger_Bridging_Header_h */
