I'm using multiple instances of an object creating a form:

BPFormInputTextFieldCell *nameCell = [[inputTextFieldClass alloc] init];
    nameCell.backgroundColor = cellBgnd;
    nameCell.textField.placeholder = @"business_name";
    nameCell.mandatory = YES;
    nameCell.textField.delegate = self;
    nameCell.customCellHeight = 40.0f;

    BPFormInputTextFieldCell *addressCell = [[inputTextFieldClass alloc] init];
    addressCell.backgroundColor = cellBgnd;
    addressCell.textField.placeholder = @"contact_name";
    addressCell.mandatory = YES;
    addressCell.textField.delegate = self;
    addressCell.customCellHeight = 40.0f;

    BPFormInputTextFieldCell *dobCell = [[inputTextFieldClass alloc] init];
    dobCell.backgroundColor = cellBgnd;
    dobCell.textField.placeholder = @"address";
    dobCell.mandatory = YES;
    dobCell.textField.delegate = self;
    dobCell.customCellHeight = 40.0f;

    BPFormInputTextFieldCell *sexCell = [[inputTextFieldClass alloc] init];
    sexCell.backgroundColor = cellBgnd;
    sexCell.textField.placeholder = @"city";
    sexCell.mandatory = YES;
    sexCell.textField.delegate = self;
    sexCell.customCellHeight = 40.0f;

    BPFormInputTextFieldCell *contexturaCell = [[inputTextFieldClass alloc] init];
    contexturaCell.backgroundColor = cellBgnd;
    contexturaCell.textField.placeholder = @"region";
    contexturaCell.mandatory = YES;
    contexturaCell.textField.delegate = self;
    contexturaCell.customCellHeight = 40.0f;

    self.formCells = @[@[nameCell, addressCell, dobCell, sexCell, contexturaCell, pesoCell, estaturaCell, actividadCell, deseoCell, cuantosKilosCell, cuantoTiempoCell, ...];

As you can see, I need to refactor this badly. The objects should also go into the array. What is the best approach?

  • \$\begingroup\$ Is BPFormInputTextFieldCell your own subclass? Why not just move all of the redundant code to the initialization and pass in the textfield placeholder to the initializer? \$\endgroup\$

  • \$\begingroup\$ hi @bazola, is not my class, is a cocoapods form generator... \$\endgroup\$ Mar 27, 2015 at 19:19
  • \$\begingroup\$ Can you subclass it? That will probably be the best approach \$\endgroup\$

I would subclass the Cell class and pass in arguments during initialization. The subclass would look something like this:


@interface MyBPFormInputTextFieldCell : BPFormInputTextFieldCell

+(MyBPFormInputTextFieldCell *) cellWithBackgroundColor:(UIColor *)color
                                                   text:(NSString *)text
                                               delegate:(Thing *)delegate



@implementation MyBPFormInputTextFieldCell

+(MyBPFormInputTextFieldCell *) cellWithBackgroundColor:(UIColor *)color
                                                   text:(NSString *)text
                                               delegate:(Thing *)delegate
                                                 height:(CGFloat)height {

    return [[MyBPFormInputTextFieldCell alloc]initWithBackgroundColor:color

-(id) initWithBackgroundColor:(UIColor *)color text:(NSString *)text mandatory:(BOOL)isMandatory delegate:(Thing *)delegate height:(CGFloat)height {
    self = [super init];
    if (self) {
        this.backgroundColor = color;
        this.textField.placeholder = text;
        this.mandatory = isMandatory;
        this.textField.delegate = delegate;
        this.customCellHeight = height;
    return self;


Then your code would look more like this:

MyBPFormInputTextFieldCell *sexCell = [MyBPFormInputTextFieldCell cellWithBackgroundColor:cellBgnd text:@"city" mandatory:YES delegate:self height:40.f];

Or alternatively for increased readability:

MyBPFormInputTextFieldCell *sexCell = [MyBPFormInputTextFieldCell cellWithBackgroundColor:cellBgnd

However I will say that if you cannot subclass the Cell class, then the way you are doing things is alright. UI code is often ugly even after you use methods like this to make it cleaner.

Finally, if most of your values are always going to be the same, then you would not need to pass in all of those arguments, you could just have the init method of your subclass automatically set all the properties (except the delegate and the text field).


As far as I can tell, the only difference between these objects is the placeholder text, right? I'm not sure how valuable it is that we have so many text fields and don't have a way of accessing them individually (to know what the user input in each... but nonetheless...).

So all we need is an array with the placeholder strings, and a for in loop.

NSArray *placeholders = @[@"business_name", @"contact_name", @"address", @"city", @"region"];

NSMutableArray *textFields = [NSMutableArray arrayWithCapacity:placeholders.count];

for (NSString *placeholder in placeholders) {
    BPFormInputTextFieldCell *textField = [[inputTextFieldClass alloc] init];
    textField.backgroundColor = cellBgnd;
    textField .textField.placeholder = placeholder;
    textField.mandatory = YES;
    textField.textField.delegate = self;
    textField.customCellHeight = 40.0f;
    [textFields addObject:textField];

self.formCells = textFields;

So much copy-and-pasting should almost always be a red flag for needing a loop.
