使用AFNetworking上传多张图像

Question

我使用，PickerController并将一些图像加载到上NSMutableArray。

现在，我需要一次上传所有这些图像。正在使用AFNetworking，我该怎么做？

我浏览了AFNetworking文档，有一个名为的部分Creating an Upload Task for a Multi-Part Request, with Progress。但是，我无法上传中的图像NSMutableArray。

*注意：我想以NSMutableArrayByte Array 的形式上传图像。我怎样才能做到这一点？*

我到目前为止的代码，

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"site.com/upload"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];

Answer 1

UIImage *image1 = [UIImage imageNamed:@"about_app"];
UIImage *image2 = [UIImage imageNamed:@"alter"];
NSArray *array = @[image1,image2];
NSMutableURLRequest *request = [[AFNetWorkSingleton shareInstance] multipartFormRequestWithMethod:@"POST" path:@"Mindex/getimg" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData>formData){
int i = 0;
for(UIImage *eachImage in array)
{
    NSData *imageData = UIImageJPEGRepresentation(eachImage,0.5);
    [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"file%d",i ] fileName:[NSString stringWithFormat:@"file%d.jpg",i ] mimeType:@"image/jpeg"];
    i++;
}
}];

试试这个。
