Requirements

iOS 8.0+ / macOS 10.13.6+
Xcode 10.1 (10B61) +

Example

To run the FFPopup project, clone the Repo, and start FFPopup in Xcode.

$ git clone https://github.com/JonyFang/FFPopup.git
$ cd FFPopup
$ cd Shell && sh install-bundle.sh && sh install-pods.sh && cd ..
$ open FFPopup.xcworkspace

Installation

There are three ways to use FFPopup in your project:

Installation with CocoaPods
Installation with Carthage
Manually install

CocoaPods

CocoaPods is a dependency manager, which automates and simplifies the process of using 3rd-party libraries like FFPopup in your projects. First, add the following line to your Podfile:

pod 'FFPopup'

If you want to use the latest features of FFPopup use normal external source dependencies.

pod 'FFPopup', :git => 'https://github.com/JonyFang/FFPopup.git'

This pulls from the master branch directly.

Second, install FFPopup into your project:

$ pod install

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate FFPopup into your Xcode project using Carthage, specify it in your Cartfile:

github "JonyFang/FFPopup"

Run the following command to build the framework:

$ carthage update

Drag the built FFPopup.framework binaries from Carthage/Build/iOS into your application’s Xcode project.

On your application targets’ Build Phases settings tab, click the + icon and choose New Run Script Phase. Create a Run Script in which you specify your shell (ex: /bin/sh), add the following contents to the script area below the shell:

/usr/local/bin/carthage copy-frameworks

Add the following paths to the frameworks you want to use under Input Files.

$(SRCROOT)/Carthage/Build/iOS/FFPopup.framework

For an in depth guide, read on from Adding frameworks to an application

Manually

Alternatively you can directly add the FFPopup.h and FFPopup.m source files to your project.

Download the latest code version or add the repository as a git submodule to your git-tracked project.
Open your project in Xcode, then drag and drop FFPopup.h and FFPopup.m onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.
Include FFPopup wherever you need it with #import "FFPopup.h".

Swift

Even though FFPopup is written in Objective-C, it can be used in Swift with no hassle. If you use CocoaPods add the following line to your Podfile:

use_frameworks!

If you added FFPopup manually, just add a bridging header file to your project with the FFPopup header included.

Usage

Import the library where you want to use it.

Objective-C

#import <FFPopup.h>

- (void)showPopup {
    FFPopup *popup = [FFPopup popupWithContentView:self.contentView showType:FFPopupShowType_BounceIn dismissType:FFPopupDismissType_ShrinkOut maskType:FFPopupMaskType_Dimmed dismissOnBackgroundTouch:YES dismissOnContentTouch:NO];
    FFPopupLayout layout = FFPopupLayoutMake(FFPopupHorizontalLayout_Center, FFPopupVerticalLayout_Center);
    [popup showWithLayout:layout];
}

Swift

import FFPopup

func showPopup() {
    let popup = FFPopup(contentView: self.contentView, showType: .bounceIn, dismissType: .shrinkOut, maskType: .dimmed, dismissOnBackgroundTouch: true, dismissOnContentTouch: false)
    let layout = FFPopupLayout(horizontal: .center, vertical: .center)
