MBProgressHUD armv7 error

Question

i'm trying to use MBProgressHUD. i added header an .m to project, imported header in class and call MBProgressHUD from an ibaction in this way:

-(IBAction)submitForm:(id)sender{
    MBProgressHUD *HUD = [[MBProgressHUD alloc] initWithView:self.view];
    [self.view addSubview:HUD];
    HUD.labelText = @"Connecting";
    [HUD show:YES];
}

when i build project it happens an error:

Undefined symbols for architecture armv7:
    "_OBJC_CLASS_$_MBProgressHUD", referenced from:
    objc-class-ref in FormViewController.o
    ld: symbol(s) not found for architecture armv7
    collect2: ld returned 1 exit status

How can i fix it? can you help me?

Looks like you are missing the `arm7` architecture for your library. Did you compile the source code of MBProgressHUD framework yourself or did you download the `.framework` or static `.a` files without building it yourself? — Michael Dautermann, Jan 13 '12 at 14:50
i've downloaded .h e .m from https://github.com/jdg/MBProgressHUD — Jayyrus, Jan 13 '12 at 15:16

In your Xcode project, select your MBProgressHUD.m file in the list of files (along the left edge of the workspace) and look at the File Inspector for that file.

Make sure the checkbox is ON for your project in the "Target Membership" setting.

Make sure Target Membership is selected for your .m file

For me this checkbox was greyed out. I deleted files, and re-added them. This checkbox appears on the "add files" screen and is not greyed out there...solved my issue. thx! – sixstatesaway Jun 27 '12 at 07:55

Just a guess, but check to make sure that MBProgressHUD.m is added to your Build Sources build phase.
