AFNetworking 上传文件、显示上传进度 - 家柱

AFNetworking2.6.0,上传文件且显示上传进度，直接贴代码：
1、只上传文件，不显示进度：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

[manager POST:URL parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:@"upfile" fileName:fileName mimeType: @"image/png"];
} success:^(AFHTTPRequestOperation * task, id responseObject) {
NSLog(@"%@",@"success");
} failure:^(AFHTTPRequestOperation * task, NSError * error) {
NSLog(@"%@",error.description);
}];

2、上传文件并显示进度

// 这里上传方法也可以合并在一起，按照上面上传文件方式，返回AFHTTPRequestOperation对象就行
AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];
NSMutableURLRequest *request = [serializer multipartFormRequestWithMethod:@"POST" URLString:URL parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
[formData appendPartWithFileData:imageData name:@"upfile" fileName:fileName mimeType: @"image/png"];
} error:nil];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {
NSLog(@"%@",@"success");
} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {
NSLog(@"%@",error.description);
}];

[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
// Wrote的值就是上传进度百分比
NSLog(@"Wrote %lld/%lld", totalBytesWritten, totalBytesExpectedToWrite);
}];

// 这里一定要start
[operation start];

希望对大家有所帮助，总结留着回顾。
