BZGFormViewController Build Status

BZGFormViewController is a simple library for making dynamic forms.

alt tag

Demo app

Navigate to

SignupForm
, run
pod install
, and open
SignupForm.xcworkspace
. Build and run to see
BZGFormViewController
in action.

Installation

Cocoapods is the recommended method of installing

BZGFormViewController
. Add the following line to your
Podfile
:
pod `BZGFormViewController`

Quick start

First, subclass

BZGFormViewController
.
objc
@interface SignupViewController : BZGFormViewController
Next, import "BZGTextFieldCell.h" and create a cell. ```objc

import "BZGTextFieldCell.h"

// ...

self.usernameCell = [BZGTextFieldCell new]; self.usernameCell.label.text = @"Username";

To validate text and update the cell when the cell's text changes, use the cell's `shouldChangeTextBlock`.
objc self.usernameCell.shouldChangeTextBlock = ^BOOL(BZGTextFieldCell *cell, NSString *newText) { if (newText.length < 5) { cell.validationState = BZGValidationStateInvalid; } else { cell.validationState = BZGValidationStateValid; } return YES; };
Each `BZGTextFieldCell` contains a `BZGInfoCell`. The info cell will be displayed if the cell's `validationState` is either `BZGValidationStateInvalid` or `BZGValidationStateWarning`. You can set the info cell's text using `setText:`.
objc self.usernameCell.shouldChangeTextBlock = ^BOOL(BZGTextFieldCell *cell, NSString *newText) { if (newText.length < 5) { cell.validationState = BZGValidationStateInvalid; [cell.infoCell setText:@"Username must be at least 5 characters long."]; } else { cell.validationState = BZGValidationStateValid; } return YES; }; ``
BZGFormViewController` automatically scrolls the tableview when you begin editing a text field and moves to the next field when you hit return.

You should use

BZGTextFieldCell
's
shouldChangeTextBlock
,
didBeginEditingBlock
,
didEndEditingBlock
, and
shouldReturnBlock
for validation and any other logic you would usually put in
UITextFieldDelegate
methods.

After you've configured your cells, add them into the desired section ```objc [self addFormCells:@[self.usernameCell, self.emailCell, self.passwordCell] atSection:0]; [self addFormCells:@[self.phoneCell] atSection:1];

## Custom sections
`BZGFormViewController` will only manage sections containing form cells. If you'd like to have other sections containing custom cells, you'll have to manage them yourself via the `UITableViewDataSource` methods. Be sure to use the values from `super` for the table view's form section.
```objc
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 3;
}

  • (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (section > 1) {

      return [super tableView:tableView numberOfRowsInSection:section];

    } else {

      return 1;

    } }

  • (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.section > 1) {

      return [super tableView:tableView cellForRowAtIndexPath:indexPath];

    } else {

      return self.otherCell;

    } }
