问题是什么?我已将完整的imagePickerController

数组中的第二个参数不应该也是您写入文件的位置吗
所以这个
NSArray *parameters = @[ @{ @"name": @"task", @"value": @"4b363547-58da-48a8-b76d-8877dd816d13" },
@{ @"name": @"image_file", @"fileName": @"/private/var/mobile/Containers/Data/Application/C7C8D8A8-B9E7-4E4E-B35C-DBFB061804D6/tmp/IMG_0082.JPG" } ];
应该是
NSArray *parameters = @[ @{ @"name": @"task", @"value": @"4b363547-58da-48a8-b76d-8877dd816d13" },
@{ @"name": @"image_file", @"fileName": path} ];
让我试试,几分钟后再打给你。
