How to ignore placeholder text in iOS6 UITextField

Question

I have a data entry app which I have developed primarily with iOS7 in focus but it will support ios 6. I noticed that when I am trying to check if a UITextField is empty when I try to validate a form in iOS6 it will tell me that it is not empty if there is a placeholder text there. In iOS 7 I don't have this problem.

Does anyone have any efficient solution for this except for matching every UITextField's content with its placeholdet text for all the UITextFields in the whole app?

EDIT: If the validation is the issue, here is my validation code. Very simply I iterate through an array with the mandatory UITextFields and check if there is any input in them.

-(void)checkIfComplete{
    BOOL complete = YES;
    for(int i = 0; i < self.mandatoryFields.count; i++){
        UITextField *tempTextField = self.mandatoryFields[i];

        if([tempTextField.text  isEqual: @""]){
            complete = NO;
        }
    }

    if(complete){
        self.btnSave.enabled = YES;
    }else{
        self.btnSave.enabled = NO;
    }
}

EDIT 2: Okey this is very weird. When I load the ViewController with the UITextFields the validation is wrong (it says the form is complete even though it is not). But if I enter a UITextField, write something and then delete what I just wrote the validation is correct (it says the form is incomplete when it is). I am setting my placeholders from the Storyboard if that makes any difference.

Thank you

Try this

-(void)checkIfComplete{
    BOOL complete = YES;
    for(int i = 0; i < self.mandatoryFields.count; i++){
        UITextField *tempTextField = self.mandatoryFields[i];

        if(tempTextField.text.length == 0){
            complete = NO;
            break;
        }
    }

    self.btnSave.enabled = complete;
}
