①封裝
創(chuàng)建一個(gè)新的類,我暫且命名為HttpRequest
.h文件
#import <Foundation/Foundation.h>
@class AFNetworking;
@interface HttpRequest : NSObject
+(HttpRequest *)sharedInstance;
-(void)GET:(NSString *)URLString dict:(id)dict succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure;
-(void)POST:(NSString *)URLString dict:(id)dict succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure;
@end
.m文件
#import "HttpRequest.h"
#import "AFNetworking.h"
@implementation HttpRequest
/**
* 創(chuàng)建網(wǎng)絡(luò)請求類的單例
*/
static HttpRequest *httpRequest = nil;
+(HttpRequest *)sharedInstance
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
if (httpRequest == nil) {
httpRequest = [[self alloc] init];
}
});
return httpRequest;
}
+(instancetype)allocWithZone:(struct _NSZone *)zone
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
if (httpRequest == nil) {
httpRequest = [super allocWithZone:zone];
}
});
return httpRequest;
}
-(instancetype)copyWithZone:(NSZone *)zone
{
return httpRequest;
}

②使用
調(diào)用時(shí)代碼很少,很方便使用(也可以把調(diào)用的代碼寫成代碼片段,提高效率)
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:<#(nonnull id), ...#>, nil nil];
HttpRequest *httpRequest = [HttpRequest sharedInstance];
[httpRequest GET:<#(NSString *)#> dict:dict succeed:^(id data) {
NSLog(@"%@", data);
} failure:^(NSError *error) {
NSLog(@"%@", error);
}];
如果不需要傳參數(shù),就不用創(chuàng)建dict了,get請求那里直接寫nil就行.
post跟get一樣,除了把get改成post,其余地方都不用改動(dòng)
