 起首一切的Model照樣應用oc來寫——看到這一句是否是想關網頁了- - #，在swift外面直接寫一向報錯所以就遷就用oc來寫了，這裡重要是分享一下搭配Alamofire應用的經歷。

注釋

 這裡不評論辯論JSONModel和Alamofire這兩個項目，直接上代碼，BaseModel.h

#import "JSONModel.h"

@interface BaseModel : JSONModel

-(instancetype)initWithDictionary:(NSDictionary*)dict;

@end

BaseModel.m

#import "BaseModel.h"

@implementation BaseModel

//Make all model properties optional (avoid if possible)
+(BOOL)propertyIsOptional:(NSString*)propertyName
{
  return YES;
}

-(instancetype)initWithDictionary:(NSDictionary*)dict {
  return (self = [[super init] initWithDictionary:dict error:nil]);
}

@end

 一切的Model都要繼續BaseModel，其他寫法都一樣

  BaseAPI.swift

internal func requestModel<T: BaseModel>(method: Method, _ URLString: URLStringConvertible, parameters: [String: AnyObject]? = nil, success: (T) -> Void, failure: (NSError?) -> Void) {
    mHttpManager.request(method, URLString , parameters: parameters, encoding: ParameterEncoding.JSON)
      .responseJSON { (request, response, data, error) in
        if error == nil {
          if let dict = data as? NSDictionary {
            if let model = T(dictionary: dict as [NSObject : AnyObject]) {
              success(model)
              return
            }
          }
        }
        failure(error)
    }
  }
  
  internal func requestArray<T: BaseModel>(method: Method, _ URLString: URLStringConvertible, parameters: [String: AnyObject]? = nil, success: (Array<T>) -> Void, failure: (NSError?) -> Void) {
    mHttpManager.request(method, URLString , parameters: parameters, encoding: ParameterEncoding.JSON)
      .responseJSON { (request, response, data, error) in
        if error == nil {
          if let array = data as? NSArray {
            if let result = T.arrayOfModelsFromDictionaries(array as [AnyObject]).copy() as? Array<T>{
              success(result)
              return
            }
          }
        }
        failure(error)
    }
  }

 代碼解釋

   1、mHttpManager這個是Alamofire的Manager對象

   2、留意辦事真個前往的數據格局，這裡支撐Model和Array<Model>

   3、留意在Swift外面NSDictionary轉Model，用T(dictionary: dict as [NSObject : AnyObject])，這個T就是詳細的泛型類型

   4、留意在Swift外面NSArray轉Model數組，用T.arrayOfModelsFromDictionaries(array as [AnyObject]).copy() as? Array<T>，留意不要用BaseModel. arrayOfModelsFromDictionaries（編譯不會報錯然則類型轉不出來）

   5、詳細用法：

 public func casts(success: (Array<CustomModel>) -> Void, failure: (NSError?) -> Void) {
        requestArray(Method.GET, URL_CASTS, parameters: nil, success: success, failure: failure)
      }
      
      public func like(id: String, success: (CustomModel) -> Void, failure: (NSError?) -> Void) {
        requestModel(Method.PATCH, String(format: URL_CASTS_LIKE, id), parameters: nil, success: success, failure: failure)
      }

以上就是在Swift中應用JSONModel 實例代碼，有須要的同伙可以參考下。
