迁移到 swift - 完成处理程序有问题

Question

我正在尝试 "translate" 来自 Objective C 的方法，因为我用 swift 做得更好，但我遇到了一个我无法解决的错误。

这是方法：

+(void) getFormObjectForWorkflowTypeId: (NSNumber *) workflowTypeId andEmployeeId: (NSNumber *) employeeId onCompletion: (void (^)(VOCForm *form)) completionHandler {

    VOCGetFormRC *configuration = [[VOCGetFormRC alloc] initWithWorkflowTypeId: workflowTypeId andEmployeeId: employeeId];
    VOCNetworkManager *networkManager = [VOCNetworkManager sharedManager];
    [networkManager startRequestWithConfiguration: configuration
                                        onSuccess:^(NSArray * _Nonnull jsonResponse) {

                                            BOOL responseState = [jsonResponse valueForKey:@"success"];

                                            if (responseState) {

                                                NSDictionary *formData = [[[jsonResponse valueForKey: @"data"] valueForKey: @"elements"] valueForKey: @"form"];

                                                NSError *error;
                                                VOCForm *form = [[VOCForm alloc] initWithDictionary: formData error: &error];

                                                if (error) {

                                                    [VOCLogUtils printLogForClass: self methodName: NSStringFromSelector(_cmd) andError: error];

                                                    if (completionHandler) {
                                                        completionHandler (nil);
                                                    }
                                                }
                                                else {

                                                    if (completionHandler) {
                                                        completionHandler (form);
                                                    }
                                                }
                                            }
                                            else {

                                                if (completionHandler) {
                                                    completionHandler(nil);
                                                }
                                            }
                                        }
                                        onFailure:^(VOCNetworkManagerResponse *networkManagerResponse) {

                                            if (completionHandler) {
                                                completionHandler(nil);
                                            }
                                        }];
}

当我尝试调用

时，问题就在一开始就出现了

networkManager.startRequest

Xcode 使用 "onCompletion" 而不是 onSuccess 自动完成方法。无论如何它都无法识别 "jsonResponse"。

在VOCNetworkManager class中有两个同名的方法（我不知道这在Objective C中是否常见）：

一个电话'onSucces'

-(void) startRequestWithConfiguration: (VOCRequestConfiguration *) configuration onSuccess: (void ( ^ _Nonnull)(NSArray * _Nonnull jsonResponse)) success
                        onFailure: (void (^)(VOCNetworkManagerResponse *networkManagerResponse)) failure {
//NSLog(@"STARTING REQUEST NETWORK MANAGER");
NSString *url = [NSString stringWithFormat: @"%@%@", configuration.baseUrl, configuration.endPoint];

第二个调用 'onCompletion'

-(void) startRequestWithConfiguration: (VOCRequestConfiguration *) configuration onCompletion: (void (^)(NSDictionary *jsonResponse, NSError *error)) completionHandler {

NSString *url = [NSString stringWithFormat: @"%@%@", configuration.baseUrl, configuration.endPoint];

[[self getNetworkingManager] POST: url parameters: configuration.parameters progress: nil
                          success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

但是从我的Swift class看来好像只能得到第二个，所以我根本无法转换方法。

这不是我第一次遇到此类 completionHandlers tbh 问题

头文件

#import <Foundation/Foundation.h>

@class VOCRequestConfiguration;
@class VOCNetworkManagerResponse;
@class VOCMultipartRequestConfiguration;

@interface VOCNetworkManager : NSObject

+(id _Nullable) sharedManager;

-(void) startRequestWithConfiguration: (VOCRequestConfiguration *_Nullable) configuration onSuccess: (void ( ^ _Nonnull)( NSArray * _Nonnull jsonResponse)) success
                            onFailure: (void (^_Nullable)(VOCNetworkManagerResponse * _Nullable networkManagerResponse)) failure;

-(void) startApplicationJSONContentRequestWithConfiguration: (VOCRequestConfiguration *_Nullable) configuration onSuccess: (void ( ^ _Nonnull)( NSArray * _Nonnull jsonResponse)) success
                            onFailure: (void (^_Nullable)(VOCNetworkManagerResponse * _Nullable networkManagerResponse)) failure;

-(void) startRequestForFile: (VOCMultipartRequestConfiguration *_Nullable) configuration onSuccess: (void (^_Nullable)(NSArray * _Nullable response)) success onFailure: (void (^_Nullable)(void)) failure;

-(void) startRequestWithConfiguration: (VOCRequestConfiguration *_Nullable) configuration onCompletion: (void (^_Nullable)(NSDictionary * _Nullable jsonResponse, NSError * _Nullable error)) completionHandler;

-(void) uploadFile: (VOCMultipartRequestConfiguration *_Nullable) configuration onSuccess: (void (^_Nullable)(NSArray * _Nullable response)) success onFailure: (void (^_Nullable)(void)) failure;

@end

Answer 1

嘿，编译器似乎想知道所有信息以使这些方法可用于 swift。

所以不用

@class VOCRequestConfiguration;
@class VOCNetworkManagerResponse;
@class VOCMultipartRequestConfiguration;

使用

#import "VOCRequestConfiguration.h"
#import "VOCNetworkManagerResponse.h"
#import "VOCMultipartRequestConfiguration.h"
