Overview
The SVGPath library is a powerful tool for working with SVG paths in your iOS application. It provides a convenient way to parse, manipulate, and generate SVG path commands.
Key Features
- Parse SVG path commands for further manipulation
- Modify existing path commands
- Create new path commands programmatically
- Generate valid SVG path strings
- Optimize and simplify path commands
Installation
Step 1: Requirements
Before using SVGPath, make sure your Xcode project meets the following requirements:
- iOS 9.0 or later
- Swift 5.0 or later
Step 2: CocoaPods
To integrate SVGPath into your Xcode project using CocoaPods, follow these steps:
- Add the following line to your Podfile:
// Podfile
platform :ios, '9.0'
use_frameworks!
target 'YourTargetName' do
pod 'SVGPath'
end
- Run the following command:
pod install
Step 3: Manual Installation
If you prefer not to use CocoaPods, you can manually add SVGPath to your project by following these steps:
- Clone or download the SVGPath repository from GitHub.
- In your Xcode project, select File > Add Files to “YourProjectName” and choose the “SVGPath.xcodeproj” file.
- In the project settings, select your target and go to the “General” tab.
- Add “SVGPath.framework” under “Frameworks, Libraries, and Embedded Content”. Make sure to set it to “Embed & Sign”.
Usage
Example 1: Parsing an SVG Path
import SVGPath
let svgPathString = "M10 10 L20 30 C40 20 50 10 60 30"
if let path = SVGPath(svgPathString: svgPathString) {
print("Parsed SVG Path: \(path.commands)")
}
Example 2: Modifying a Path Command
import SVGPath
let svgPathString = "M10 10 L20 30 C40 20 50 10 60 30"
if let path = SVGPath(svgPathString: svgPathString) {
if let command = path.commands.first as? LineToCommand {
command.x = 50
command.y = 50
}
print("Modified SVG Path: \(path.svgPathString)")
}
Example 3: Creating a New Path Command
import SVGPath
let path = SVGPath()
path.moveTo(x: 10, y: 10)
path.lineTo(x: 20, y: 30)
path.curveTo(x1: 40, y1: 20, x2: 50, y2: 10, x: 60, y: 30)
print("New SVG Path: \(path.svgPathString)")
Example 4: Generating SVG Path String
import SVGPath
let path = SVGPath()
path.moveTo(x: 10, y: 10)
path.lineTo(x: 20, y: 30)
path.curveTo(x1: 40, y1: 20, x2: 50, y2: 10, x: 60, y: 30)
print("Generated SVG Path String: \(path.svgPathString)")
Example 5: Optimizing and Simplifying Path Commands
import SVGPath
let svgPathString = "M10 10 L20 30 C40 20 50 10 60 30"
if let path = SVGPath(svgPathString: svgPathString) {
path.optimize()
print("Optimized SVG Path: \(path.svgPathString)")
}
