系统要求

iOS7+ project
ARC project

安装

CocoaPods 安装

将下面代码复制进你的 Podfile 文件中

pod 'StitchingImage', :git => 'https://github.com/zhengjinghua/StitchingImage.git'

手工安装

下载此项目, 并将该项目里的 Classes 文件夹里的所有文件复制进你的项目中, 然后在需要调用此项目的地方引入 #import "StitchingImage.h" .

使用

1. 收集头像数组

// 将你要拼接的头像文件放入到一个 NSMutableArray 中
NSMutableArray *imageViews = [[NSMutableArray alloc] init];
    
UIImageView *imageView_1 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
imageView_1.image = [UIImage imageNamed:@"1.jpg"];
[imageViews addObject:imageView_1];
    
UIImageView *imageView_2 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
imageView_2.image = [UIImage imageNamed:@"2.jpg"];
[imageViews addObject:imageView_2];

2. 准备好画布

// 生成一个背景 canvasView, 用于存放拼接好的群组封面, 相当于背景.
UIImageView *canvasView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
canvasView.layer.cornerRadius = 10;
canvasView.layer.masksToBounds = YES;
canvasView.backgroundColor = [UIColor colorWithWhite:0.839 alpha:1.000];

3. 绘画并生成

// 现在你可以调用以下方法, 将用户的头像画到指定的 canvasView 上
UIImageView *coverImage = [[StitchingImage alloc] stitchingOnImageView:canvasView withImageViews:imageViews];

[self.view addSubview:coverImage];

4. 修改 Margin

// 如果你想自定义生成的群组封面里的 margin 值, 你可以调用以下方法
UIImageView *coverImage = [[StitchingImage alloc] stitchingOnImageView:canvasView withImageViews:imageViews marginValue:15.0f];

[self.view addSubview:coverImage];

Requirements

iOS7+ project
ARC project

Install

CocoaPods

If you're using CocoaPods (You are not?! You should!!) just add

pod 'StitchingImage', :git => 'https://github.com/zhengjinghua/StitchingImage.git'

into your Podfile file.

Manually

Download the project and copy the Classes folder into your project and then simply #import "StitchingImage.h" in the file(s) you would like to use it in.

Usage

1. Create NSMutableArray for image views

NSMutableArray *imageViews = [[NSMutableArray alloc] init];
    
UIImageView *imageView_1 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
imageView_1.image = [UIImage imageNamed:@"1.jpg"];
[imageViews addObject:imageView_1];
    
UIImageView *imageView_2 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
imageView_2.image = [UIImage imageNamed:@"2.jpg"];
[imageViews addObject:imageView_2];

2. Create a canvasView

UIImageView *canvasView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
canvasView.layer.cornerRadius = 10;
canvasView.layer.masksToBounds = YES;
canvasView.backgroundColor = [UIColor colorWithWhite:0.839 alpha:1.000];

3. Stitching images

UIImageView *coverImage = [[StitchingImage alloc] stitchingOnImageView:canvasView withImageViews:imageViews];

[self.view addSubview:coverImage];

4. Change margin value

UIImageView *coverImage = [[StitchingImage alloc] stitchingOnImageView:canvasView withImageViews:imageViews marginValue:15.0f];

[self.view addSubview:coverImage];
