MTBlockAlertView Convenience Methods cause ucol_getVersion bad_access

[horstleung]

Temporary solved by calling MTBlockAlertView in async way:

+ (void) showWithTitle:(NSString *)title
               message:(NSString *)message
     cancelButtonTitle:(NSString *)cancelButtonTitle
      otherButtonTitle:(NSString *)otherButtonTitle
        alertViewStyle:(UIAlertViewStyle)alertViewStyle
       completionBlock:(void (^)(UIAlertView *alertView, NSInteger buttonIndex))completionBlock {


    dispatch_async(dispatch_get_main_queue(), ^{
        MTBlockAlertView *alertView = [[MTBlockAlertView alloc] initWithTitle:title
                                                                      message:message
                                                            completionHanlder:completionBlock
                                                            cancelButtonTitle:cancelButtonTitle
                                                            otherButtonTitles:otherButtonTitle, nil];

        alertView.alertViewStyle = alertViewStyle;
        [alertView show];
    });
}

I don't know if it is a good way to solve it, but at least it works.
