ios - Objective-C中的“发现扩展时遇到的错误”

Question

我正在使用UIImagePickerController将用户选择的图像发送到API，但是出现此错误:
warning: could not execute support code to read Objective-C class data in the process. This may reduce the quality of type information available.
[discovery] errors encountered while discovering extensions: Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled}
这是发生错误的代码:

NSError *error;
NSMutableString *body = [NSMutableString string];
for (NSDictionary *param in parameters) {
    [body appendFormat:@"--%@\r\n", boundary];
    if (param[@"fileName"]) {
        [body appendFormat:@"Content-Disposition:form-data; name=\"%@\"; filename=\"%@\"\r\n", param[@"name"], param[@"fileName"]];
        [body appendFormat:@"Content-Type: %@\r\n\r\n", param[@"contentType"]];
        [body appendFormat:@"%@", [NSString stringWithContentsOfFile:param[@"fileName"] encoding:NSMacOSRomanStringEncoding/*NSUTF8StringEncoding*/ error:&error]];
        if (error) {
            NSLog(@"%@", error);
        }
    } else {
        [body appendFormat:@"Content-Disposition:form-data; name=\"%@\"\r\n\r\n", param[@"name"]];
        [body appendFormat:@"%@", param[@"value"]];
    }
}
[body appendFormat:@"\r\n--%@--\r\n", boundary];
NSData *postData = [body dataUsingEncoding:NSUTF8StringEncoding];

该代码在此方法内部: (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info。

这是什么问题？

对我有用的解决方案只是进入Product(在屏幕顶部)-> Scheme-> EditScheme-> Arguments

在环境变量中，添加OS_ACTIVITY_MODE的值为“禁用”

希望这对其他人有用!

我将附上屏幕截图，以防我的描述令人困惑
