Demo Project

To run the example project, clone the repo, and run pod install from the Example directory first.

Getting Started

Requirements

Requires iOS SDK version > 7.0

Requires ARC

Installation with CocoaPods

CocoaPods is a 3rd-party dependency manager for Swift and Objective-C projects. For more information, refer to the CocoaPods Getting Started Guide. Otherwise, you can install CocoaPods with the following command:

$ gem install cocoapods

Podfile

To integrate MEVHorizontalContacts into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
pod 'MEVHorizontalContacts'

Then, run the following command:

$ pod install

Installation Manually

To integrate MEVHorizontalContacts into your Xcode project manually, just include the filest from /Pod/Classes/ folder in your App’s Xcode project.

Then, import the following file your classes:

#import "MEVHorizontalContacts.h"

Quick Guide

Usage

1. Import class
#import "MEVHorizontalContacts.h"
2. Add Datasource and Delegate protocols.
@interface ViewController () <MEVHorizontalContactsDataSource, MEVHorizontalContactsDelegate>
@property (nonatomic, strong) MEVHorizontalContacts *horizontalContacts;
@end
3. Create, initialize and add MEVHorizontalContacts view.
_horizontalContacts = [MEVHorizontalContacts new];
_horizontalContacts.backgroundColor = [UIColor whiteColor];
_horizontalContacts.dataSource = self;
_horizontalContacts.delegate = self;
[self addSubview:_horizontalContacts];
[self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[horizontalContacts]|" options:NSLayoutFormatAlignAllCenterX metrics:nil views:@{@"horizontalContacts" : _horizontalContacts}]];
[self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[horizontalContacts]|" options:NSLayoutFormatAlignAllCenterY metrics:nil views:@{@"horizontalContacts" : _horizontalContacts}]];
4. Implement Datasource Methods
#pragma mark - MEVHorizontalContactsDataSource Methods

- (NSInteger)numberOfContacts;
- (NSInteger)numberOfItemsAtContactIndex:(NSInteger)index;
- (MEVHorizontalContactsCell *)contactAtIndex:(NSInteger)index;
- (MEVHorizontalContactsCell *)item:(NSInteger)item atContactIndex:(NSInteger)index;
- (UIEdgeInsets)horizontalContactsInsets;
- (NSInteger)horizontalContactsSpacing;

5. Implement Delegate Methods
#pragma mark - MEVHorizontalContactsDelegate Methods

- (void)contactSelectedAtIndex:(NSInteger)index;
- (void)item:(NSInteger)item selectedAtContactIndex:(NSInteger)index;

Example

Customization 1

- (MEVHorizontalContactsCell *)contactAtIndex:(NSInteger)index {
    MEVHorizontalContactsCell *cell = [_horizontalContacts dequeueReusableContactCellForIndex:index];
    [cell.imageView setImage:[UIImage imageNamed:[self getImageNameAtIndex:index]]];
    [cell.imageView.layer setBorderColor:[UIColor colorWithRed:34/255.0f green:167/255.0f blue:240/255.0f alpha:1].CGColor];
    [cell.imageView.layer setBorderWidth:1.0f];
    [cell.label setText:[self getUserNameAtIndex:index]];
    [cell.label setFont:[UIFont boldSystemFontOfSize:12.0f]];
    return cell;
}

- (MEVHorizontalContactsCell *)item:(NSInteger)item atContactIndex:(NSInteger)index {

    UIImage *image;
    NSString *labelText;
    switch (item) {
        case 0:
            labelText = @"Call";
            image = [UIImage imageNamed:@"actionCall"];
            break;
        case 1:
            labelText = @"Email";
            image = [UIImage imageNamed:@"actionEmail"];
            break;
        case 2:
            labelText = @"Message";
            image = [UIImage imageNamed:@"actionMessage"];
            break;
        default:
            labelText = @"Call";
            image = [UIImage imageNamed:@"actionCall"];
            break;
    }
    
    MEVHorizontalContactsCell *cell = [_horizontalContacts dequeueReusableItemCellForIndex:index];
    [cell.imageView setImage:image];
    [cell.imageView setTintColor:[UIColor colorWithRed:34/255.0f green:167/255.0f blue:240/255.0f alpha:1]];
    [cell.imageView.layer setBorderColor:[UIColor colorWithRed:34/255.0f green:167/255.0f blue:240/255.0f alpha:1].CGColor];
    [cell.imageView.layer setBorderWidth:1.0f];
    [cell.label setText:labelText];
    [cell.label setFont:[UIFont boldSystemFontOfSize:10.0f]];

    return cell;
}

    [cell.imageView setImage:[UIImage imageNamed:[self getImageNameAtIndex:index]]];
    [cell.label setText:[self getUserNameAtIndex:index]];
    return cell;
}

- (MEVHorizontalContactsCell *)item:(NSInteger)item atContactIndex:(NSInteger)index {
    
    UIImage *image;
    NSString *labelText;
    switch (item) {
        case 0:
            labelText = @"Call";
            image = [UIImage imageNamed:@"actionCall"];
            break;
        case 1:
            labelText = @"Email";
            image = [UIImage imageNamed:@"actionEmail"];
            break;
        case 2:

            image = [UIImage imageNamed:@"actionCall"];
            break;
    }
    
    MEVHorizontalContactsCell *cell = [_horizontalContacts dequeueReusableItemCellForIndex:index];
    [cell.imageView setImage:image];
    [cell.imageView setBackgroundColor:[UIColor colorWithRed:34/255.0f green:167/255.0f blue:240/255.0f alpha:1]];
    [cell.imageView setTintColor:[UIColor whiteColor]];
    [cell.label setText:labelText];
