MTZTableViewManager is a powerful framework that allows you to create table views in a descriptive way, by specifying rows and sections without having to bother with indexes. It also provides a set of tools for creating forms and handling their input, applying masks, performing validations and converting to and from complex objects.

Installation

Manual

• Make sure to pick the right tag (1.1.3 at the moment).
• Drop the file MTZTableViewManager.xcodeproj inside your Xcode project.
• Make sure your submodules are up-to-date.
• Drag the MTZTableViewManager.framework (under Products) to your target Linked Frameworks and Libraries area.

Sample Usage

Rows, sections and data

Getting started is fairly simple. Just declare a strongly-held MTZTableManager somewhere:

@property (nonatomic) MTZTableManager *tableManager;

Then declare your rows, sections and finally the data. Using a custom UITableViewCell subclass is recommended.

MTZTableRow *row = [[MTZTableRow alloc] initWithClazz:[MyCustomCell class] action:^(NSIndexPath * _Nonnull indexPath, id<MTZModel> model) {
        NSLog(@"Tap!");
    }];
MTZTableSection *section = [[MTZTableSection alloc] initWithTableRows:@[row]];
MTZTableData *data = [[MTZTableData alloc] initWithTableSections:@[section]];
self.tableManager = [[MTZTableManager alloc] initWithTableView:self.tableView tableData:data];

And you're good to go! Please note you cannot be the tableViews delegate or data source while using MTZTableManager.

• You can also provide a regular and/or expanded height to a row, and it will toggle between them upon selection.
• You can also hide rows or sections dinamically, just set the hidden property.
• You can instantiate cells using nibs as well. Likewise you can provide custom headers and footers classes for every section.

Models

To declare an object as a possible model, just conform it to MTZModel:

@interface MyCustomCellModel: NSObject<MTZModel>
@property (nonatomic) NSString *text;
@end

Cells can then be configured to display information. Simply conform the cell you want to MTZModelDisplaying and implement the required method:

@interface MyCustomCell: UITableViewCell <MTZModelDisplaying>
@end

@implementation MyCustomCell
- (void)configureWithModel:(id<MTZModel>)model {
    self.textLabel.text = ((MyCustomCellModel *)model).text;
}
@end

• Sections can also have models, and they're provided to custom headers/footers, if any, as long as their classes also conform to MTZModelDisplaying.

Forms

Form objects

Form objects are objects that can be manipulated by a form generated by MTZTableViewManager. Ideally, you want to make all of its properties read-only to avoid external mutation, since the form elements will modify the values directly via KVO. If you're using Swift. Don't forget the dynamic keyword for that! Make sure the object conforms to MTZFormObject:

@interface MyCustomFormObject: NSObject <MTZFormObject>
@property (nonatomic, readonly) NSString *title;
@property (nonatomic, readonly) NSDate *date;
@property (nonatomic, readonly) MyCustomUser *user;
@end

Form rows

For a cell to be compatible with a form, it needs to conform with MTZFormEditing and implement the required method:

@interface MyCustomTextFieldCell: UITableViewCell <MTZFormEditing>
@property (nonatomic) UITextField *textField;
@end

@implementation MyCustomTextFieldCell
// ...
- (UIControl<MTZFormField> *)fieldForFormObject {
    return self.textField;
}
@end

• Note that the form fields must conform to MTZFormField. The framework already provides a default implementation for UITextField, UITextView, UISwitch and UIStepper.

Form fields input accessory view

Form fields automatically provide you with inputAccessoryView for jumping between other fields within the same section. To localise the buttons on the framework-provided input accessory view, simply add the following entries to your  Localizable.strings, replacing the translations to whatever fits your needs:

"mtz_prev" = "Prev";
"mtz_next" = "Next";
"mtz_done" = "Done";

• If the keyboard provides a return button, the "Done" button is ommitted.

Form date rows

Dates are a special topic. Due to that, if you want to interact with a NSDate key path, use MTZTableFormDateRow instead:

MTZTableFormDateRow *dateRow = [[MTZTableFormDateRow alloc] initWithClazz:[MyCustomTextFieldCell class] formObject:self.formObject keyPath:CLASSKEY(MyCustomFormObject, date)];
dateRow.minimumDate = [NSDate date];
dateRow.maximumDate = [[NSDate date] dateByAddingTimeInterval:60*60*24*15];
dateRow.datePickerMode = MTZDatePickerModeDateAndTime;

• MTZTableFormDateRow must also use UITextField as a form field, as we replace the inputView with the adequate picker.
• You can also use MTZDatePickerModeExpirationDate as a picker mode, and it will use the MTZExpirationDatePicker as inputView.

Form options

If you want to provide a set of options, do so by conforming the type of object you want to provide as an option to MTZFormOption:

@interface MyCustomUser: NSObject <MTZFormOption>
@property (nonatomic) NSInteger ID;
@property (nonatomic) NSString *email;
- (instancetype)initWithID:(NSInteger)ID email:(NSString *)email;
@end

@implementation MyCustomUser
// ...
- (NSString *)optionDescription {
return self.email;
}
@end

Then set the availableOptions property on the MTZTableFormRow:

NSArray *allUsers = @[[[MyCustomUser alloc] initWithID:1 email:@"[email protected]"],
                          [[MyCustomUser alloc] initWithID:2 email:@"[email protected]"],
                          [[MyCustomUser alloc] initWithID:3 email:@"[email protected]"]];
MTZTableFormRow *userRow = [[MTZTableFormRow alloc] initWithClazz:[MyCustomTextFieldCell class] formObject:self.formObject keyPath:CLASSKEY(MyCustomFormObject, user)];
userRow.availableOptions = allUsers;

• If you set available options, you must also use UITextField as a form field, as we replace the inputView with the adequate picker.
