Installation

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 MHWhiteboard into your Xcode project using Carthage, specify it in your Cartfile:

github "MakeHui/MHWhiteboard"

Run carthage update to build the framework and drag the built MHWhiteboard.xcodeproj into your Xcode project.

Usage

#import <MHWhiteboard/MHWhiteboard.h>

MHWhiteboardView *whiteboardView = [[MHWhiteboardView alloc] initWithFrame:CGRectMake(0, 0, 375, 500)];

[whiteboardView setBrushColor:[UIColor redColor]];	// 设置画笔颜色
[whiteboardView setBrushWidth:10.0f];	// 设置画笔宽度
[whiteboardView setForegroundImage:[UIImage new]];	// 设置前景图片
[whiteboardView setBackgroundImage:[UIImage new]];	// 设置背景图片
[whiteboardView undo];	// 撤销
[whiteboardView repeat]; // 回撤
[whiteboardView clearBackgroundImage];	// 清除背景图片
[whiteboardView clearAll];	// 清空白板

// Set current tool
typedef NS_OPTIONS(NSUInteger, MHPathModelAction) {
    MHPathModelActionLine = 1 << 16,
    MHPathModelActionStraightLine = 1 << 17,
    MHPathModelActionCircle = 1 << 18,
    MHPathModelActionRectangle = 1 << 19,
    MHPathModelActionPolygon = 1 << 20,
    MHPathModelActionText = 1 << 21,
    // MHPathModelActionSmear = 1 << 22,
    // MHPathModelActionMosaic = 1 << 23,
};

whiteboardView.pathModelAction = MHPathModelAction;
