1、封裝AFNetworking基本請求方法
封裝原因：當AFNetworking的api改變的時候只需要更改封裝的方法，無需大面積改動代碼（不封裝直接用AFNetworking請求如果AFNetworking的api變化所有用的地方都需要變化）
代碼依賴了MBProgressHUD，顯示加載圖
封裝思路接口：
1、主要封裝了Get Post請求帶HUD和不帶HUD的另外一個可以選擇是否帶HUD的接口
2、將上傳圖片的單獨封裝
3、封裝了https加載證書驗證的方法，只需要設置cer文件的路徑名稱，以及是否需要https驗證
代碼如下：

#import <Foundation/Foundation.h>
#import "NetStatusData.h"
@interface HttpRequstData : NSObject

//置為NO，主要用于這種情況：客戶端請求的是子域名，而證書上的是另外一個域名。因為SSL證書上的域名是獨立的，假如證書上注冊的域名是www.google.com，那么mail.google.com是無法驗證通過的；當然，有錢可以注冊通配符的域名*.google.com，但這個還是比較貴的。

2、封裝網絡狀態監測
思路：用了一個單例，每次請求接口的時候調用小網絡狀態監測api
根據不同的網絡情況顯示提示
#import <Foundation/Foundation.h>
@interface NetStatusData : NSObject
@property(nonatomic,assign)AFNetworkReachabilityStatus status;//網絡狀態
+(NetStatusData*)shareNetStatus;
-(void)checkNetStatus;//檢查網絡狀態
@end
static NetStatusData *_netStatus = nil;
@implementation NetStatusData
+(NetStatusData *)shareNetStatus {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
if (!_netStatus) {
_netStatus = [NetStatusData new];
}
});
return _netStatus;
}
-(void)checkNetStatus {
AFNetworkReachabilityManager *manager=[AFNetworkReachabilityManager sharedManager];
__weak AFNetworkReachabilityManager *weakManager = manager;
[manager startMonitoring];
//檢測網絡狀態有網絡，網絡請求數據，沒網絡提示
[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
self.status = status;
if (!status) {//未連接
UIWindow *window = [[UIApplication sharedApplication].windows lastObject];
UILabel *tipsLable;
if (!tipsLable) {
tipsLable = [[UILabel alloc] initWithFrame:(CGRect){kScreenWidth/2,kScreenHeight/2+80,110,33}];
tipsLable.textColor = [UIColor whiteColor];
tipsLable.textAlignment = NSTextAlignmentCenter;
tipsLable.centerX = window.centerX;
tipsLable.backgroundColor = [UIColor blackColor];
tipsLable.text = @"網絡未連接";
}
[window addSubview:tipsLable];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[tipsLable removeFromSuperview];
});
return;
}else{//連接請求數據
// [self requstData:type];
}
[weakManager stopMonitoring];
}];
}
@end
3、數據解析層（核心思想）
注：利用基類做類別封裝請求，可以直接用模型請求接口，并且封裝解析過程。根據不同的模型及json類型動態解析數據。后期代碼免去解析代碼
代碼分為兩部分，一部分代碼解析，一部分數據請求
1、數據請求
#import <Foundation/Foundation.h>
@interface NSObject (Request)
//請求數據
+(void)requestUrl:(NSString*)url parameters:(NSDictionary*)parameters showHUD:(BOOL)show success:(void(^)(id responseObject)) success failure:(void(^)(NSError *error)) failure;
+(void)requestUrl:(NSString*)url parameters:(NSDictionary*)parameters success:(void(^)(id responseObject)) success failure:(void(^)(NSError *error)) failure;
+(void)requestNoHUDUrl:(NSString*)url parameters:(NSDictionary*)parameters success:(void(^)(id responseObject)) success failure:(void(^)(NSError *error)) failure;
//解析數據
+(id)parseData:(id)responseObject;
//對象轉json
-(NSDictionary*)toJson;
//獲取屬性的類型
+(NSString*)getPropertyType:(NSString*)property;
-(NSString*)getPropertyType:(NSString*)property;
@end
#import "NSObject+Request.h"
#import <objc/runtime.h>
@implementation NSObject (Request)
+(void)requestUrl:(NSString*)url parameters:(NSDictionary*)parameters showHUD:(BOOL)show success:(void(^)(id responseObject)) success failure:(void(^)(NSError *error)) failure {
[HttpRequstData postUrl:url parameters:parameters showHUD:show success:^(id responseObject) {
id obj = [self parseData:responseObject[@"data"]];
success(obj);
} failure:^(NSError *error) {
failure(error);
}];
}
+(void)requestUrl:(NSString*)url parameters:(NSDictionary*)parameters success:(void(^)(id responseObject)) success failure:(void(^)(NSError *error)) failure {
[self requestUrl:url parameters:parameters showHUD:YES success:success failure:failure];
}
+(void)requestNoHUDUrl:(NSString *)url parameters:(NSDictionary *)parameters success:(void (^)(id))success failure:(void (^)(NSError *))failure {
[self requestUrl:url parameters:parameters showHUD:NO success:success failure:failure];
}
+(id)parseData:(id)responseObject {
id obj;
//單個對象
if ([responseObject isKindOfClass:[NSDictionary class]]) {
obj = [[self alloc]init];
[obj setValuesForKeysWithDictionary:responseObject];
}
// 多個對象
else if ([responseObject isKindOfClass:[NSArray class]]) {
obj = [NSMutableArray new];
for (NSDictionary *dic in responseObject) {
id o = [[self alloc]init];
[o setValuesForKeysWithDictionary:dic];
[obj addObject:o];
}
}
return obj;
}
-(NSDictionary *)toJson
{
NSMutableDictionary *params = [NSMutableDictionary dictionary];
unsigned int count = 0;
Ivar *ivars = class_copyIvarList(self.class, &count);
for (int i = 0; i < count; i++) {
const char *cname = ivar_getName(ivars[i]);
NSString *name = [NSString stringWithUTF8String:cname];
NSString *key = [name substringFromIndex:1];
id value = [self valueForKey:key];
if ([value isKindOfClass:[NSString class]]&&[(NSString*)value length]) {
[params setValue:value forKey:key];
}
}
return params;
}
#pragma mark-------//獲取屬性的類型
+(NSString *)getPropertyType:(NSString *)property {
//獲取對象的類型objc_getClass("UserModel")
objc_property_t p = class_getProperty(self, property.UTF8String);
if (!p) {
return nil;
}
const char *cname = property_getAttributes(p);
DDLog(@"%s==",cname);
// 2.成員類型
NSString *attrs = @(property_getAttributes(p));
NSUInteger dotLoc = [attrs rangeOfString:@","].location;
NSString *code = nil;
NSUInteger loc = 3;
if (dotLoc == NSNotFound) { // 沒有,
code = [attrs substringFromIndex:loc];
} else {
code = [attrs substringWithRange:NSMakeRange(loc, dotLoc - loc-1)];
}
DDLog(@"%@===%@====",code,attrs);
return code;
}
-(NSString *)getPropertyType:(NSString *)property {
//獲取對象的類型objc_getClass("UserModel")
objc_property_t p = class_getProperty(self.class, property.UTF8String);
if (!p) {
return nil;
}
const char *cname = property_getAttributes(p);
DDLog(@"%s==",cname);
// 2.成員類型
NSString *attrs = @(property_getAttributes(p));
NSUInteger dotLoc = [attrs rangeOfString:@","].location;
NSString *code = nil;
NSUInteger loc = 3;
if (dotLoc == NSNotFound) { // 沒有,
code = [attrs substringFromIndex:loc];
} else {
code = [attrs substringWithRange:NSMakeRange(loc, dotLoc - loc-1)];
}
DDLog(@"%@===%@====",code,attrs);
return code;
}
@end
2、數據解析
思路：通過kvc解析數據，判斷json的key值是否是json和數組是的話進一步解析。不是的話直接賦值，解決復雜類型的json動態解析。
注意：數據字段的時候需要指明數據放的對象類型
使用時需要解析的模型類需要繼承Model類
/*
*對象中含有的模型數據對應的對象名稱例如
*@{
@"statuses" : @"Status",===字段有statuses的數組含有的對象為Status類型
*};
*/
@property(nonatomic,strong)NSDictionary *classInArrayDic;
代碼如下
#import <Foundation/Foundation.h>
#import "NSObject+Request.h"
@interface Model : NSObject<NSCoding,NSCopying>
//對象轉json
-(NSDictionary*)toJson;
/*
*對象中含有的模型數據對應的對象名稱例如
*@{
@"statuses" : @"Status",===字段有statuses的數組含有的對象為Status類型
*};
*/
@property(nonatomic,strong)NSDictionary *classInArrayDic;
@end
#import "Model.h"
@implementation Model
-(void)setValue:(id)value forKey:(NSString *)key{
if ([value isKindOfClass:[NSNumber class]]) {
[self setValue:[NSString stringWithFormat:@"%@",value] forKey:key];
}else if ([value isKindOfClass:[NSArray class]]) {
}else{
if (!value||[value isKindOfClass:[NSNull class]]) {
[super setValue:@"" forKey:key];
}else{
[super setValue:value forKey:key];
}
}
}
-(void)setValue:(id)value forUndefinedKey:(NSString *)key{
if ([key isEqualToString:@"description"]) {
[self setValue:value forKey:@"descriptionStr"];
}else if ([key isEqualToString:@"id"]){
[self setValue:value forKey:@"Id"];
}else if([key isEqualToString:@"newPrice"]){
[self setValue:value forKey:@"price"];
}else if([key isEqualToString:@"code"]){
[self setValue:value forKey:@"codePara"];
}else{
DDLog(@"沒有key＝＝%@",key);
}
}
-(void)setValuesForKeysWithDictionary:(NSDictionary<NSString *,id> *)keyedValues {
for (NSString *key in keyedValues) {
id value = keyedValues[key];
//對象中含有對象數組
if ([value isKindOfClass:[NSArray class]]) {
if (![self.classInArrayDic objectForKey:key]) {
DDLog(@"請給數組對象對應類型");
continue;
}
//設置數組的值
NSMutableArray *values = [NSMutableArray new];
//取出數組含有對象類型
Class ObjectType = NSClassFromString(self.classInArrayDic[key]);
DDLog(@"%@",ObjectType);
for (NSDictionary *dic in value) {
//獲取對象類型生成實例
id obj = [[ObjectType alloc]init];
[obj setValuesForKeysWithDictionary:dic];
[values addObject:obj];
}
[self setValue:values forKey:key];
}else if ([value isKindOfClass:[NSDictionary class]]) {//對象中含有對象
//獲取對象的類型
NSString *type = [self getPropertyType:key];
if (type.length) {

}
