实现af 3.0 以后 图片多张上传的封装 没升级3.0的af 更便捷，不知为何被舍弃掉了，只能自己搞下了。不过已封装好。
封装一下还是挺方便的。都已整理好，复制即可
1. 把图片数组转为data数据 副值与新的数组
NSMutableArray*array=[NSMutableArray array];
for (int i=0; i<_ImagePothosView.selectedPhotos.count; i++) {
UIImage*image=_ImagePothosView.selectedPhotos[i];
NSData *data=UIImageJPEGRepresentation(image, 0.3);
[array addObject:data];
}
2. 根据要求设置相应参数
NSMutableDictionary*dictionary=[NSMutableDictionary dictionary];
dictionary[@"userId"]=UID;
3. 调取上传的a f 3.0方法
[[ApiHttpTool sharedClient]uploadMostImageWithURLString:WPuploadpicServerUrl parameters:dictionary uploadDatas:array success:^(id json){
NSLog(@"%@",json);
} failure:^(NSError *erroe) {
}];
#pragma mark -- 图片上传 --
- (void)uploadMostImageWithURLString:(NSString *)URLString
parameters:(id)parameters
uploadDatas:(NSArray *)uploadDatas
success:(void (^)(id))success
failure:(void (^)())failure{
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
4设置 超时时间
manager.requestSerializer.timeoutInterval = 60.f;
[manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];
[manager POST:URLString parameters:parameters constructingBodyWithBlock:^(id< AFMultipartFormData > _Nonnull formData) {
for (int i=0; I<uploadDatas.count; I++){
5根据 图片文件设置。 img／jpg格式
NSString *imageName = [NSString stringWithFormat:@"%@[%i]", @"img", i];
[formData appendPartWithFileData:uploadDatas[i] name:@"img" fileName:imageName mimeType:@"image/jpeg"];
} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"%@",responseObject);
if (success) {
success(responseObject);
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if (failure) {
failure(error);
}
}];
