正確使用cocoaPods 在OC中集成Charts第三方庫

之前的看到的都是錯誤的！！！！！！！！！！！！

正確的步驟如下：

1.安裝cocoaPods

2.新建一個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.將工程中Pods的編譯語言設置爲SWIFT最新版本

    build Settings ->Swift Language Version

5.將Chart.framework添加到新建的項目中

    點擊新建的項目->Build Phases->Link Binary With Libraries-> "+" -> 找到Charts.frame添加

6.添加OC與Switf橋接

   

    在工程中新建一個Swift文件，名字隨便取，如"Chart-Bridging-Header.h"，這時候會提示是否建立橋接文件，直接選Create Bridging Header選項，名字無       所謂，會自動建立一個橋接文件。

    在橋接文件裏寫入

    @import Charts;

6.測試

#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
