我是靠谱客的博主鳗鱼黄蜂，这篇文章主要介绍iOS使用AFN进行单图和多图上传的实例代码，现在分享给大家，希望可以做个参考。

图片上传时必要将图片进行压缩,不然会上传失败

1.单张图上传

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];  [manager POST:urlString parameters:params constructingBodyWithBlock:^(id_Nonnull formData) {

//使用日期生成图片名称

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss";

NSString *fileName = [NSString stringWithFormat:@"%@.png",[formatter stringFromDate:[NSDate date]]];

[formData appendPartWithFileData:imageData name:@"uploadFile" fileName:fileName mimeType:@"image/png"];

} success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {

//上传图片成功执行回调

completion(responseObject,nil);

} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {

//上传图片失败执行回调

completion(nil,error);

}];

2.多图上传

多图上传和单图上传区别在于文件名称

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];  [manager POST:urlString parameters:params constructingBodyWithBlock:^(id_Nonnull formData) {

NSInteger imgCount = 0;

for (NSData *imageData in imageDatas) {

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss:SSS";

NSString *fileName = [NSString stringWithFormat:@"%@%@.png",[formatter stringFromDate:[NSDate date]],@(imgCount)];

[formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"uploadFile%@",@(imgCount)] fileName:fileName mimeType:@"image/png"];

imgCount++;

}

} success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {

completion(responseObject,nil);

} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {

completion(nil,error);

}];
