正确使用cocoaPods 在OC中集成Charts第三方库

之前的看到的都是错误的！！！！！！！！！！！！

正确的步骤如下：

1.安装cocoaPods

2.新建一个OC工程

3.pod init  到 vi Podfile 

# Uncomment the next line to define a global platform for your project
 platform :ios, '11.2'

target 'Chartsssss' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  use_frameworks!

  pod 'Charts'

  target 'ChartsssssTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'ChartsssssUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

4.将工程中Pods的编译语言设置为SWIFT最新版本

    build Settings ->Swift Language Version

5.将Chart.framework添加到新建的项目中

    点击新建的项目->Build Phases->Link Binary With Libraries-> "+" -> 找到Charts.frame添加

6.添加OC与Switf桥接

    在工程中新建一个Swift文件，名字随便取，如"Chart-Bridging-Header.h"，这时候会提示是否建立桥接文件，直接选Create Bridging Header选项，名字无       所谓，会自动建立一个桥接文件。

    在桥接文件里写入

    @import Charts;

6.测试

#import "ViewController.h"
#import "Chart-Bridging-Header.h"
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    BarChartView *chatView=[[BarChartView alloc]initWithFrame:CGRectMake(0, 40, 300, 300)];
    chatView.backgroundColor=[UIColor blueColor];
    [self.view addSubview:chatView];
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


@end
