iOS 中集成百度echarts3.0

突然项目中要用到图表，所以就用了百度的echarts，然后就是网上搜了一下，由于本人的JS不是很熟悉，但是研究了一下还是做出来了，其实也不是很难
最后做的效果大概如下图这种，由于界面上没调整，所以粗糙了一点
不多说前端的代码如下

这里做的只是一个测试项目，所以json 里面的数据都是一样的

控制器中设立了一个表格然后读取本地的数据

#import "ViewController.h"

#import "HistoryDateCell.h"

#import "HistoryDateModel.h"

#import "MJExtension.h"

@interface ViewController ()<UITableViewDelegate,UITableViewDataSource>

/** 表格 */

@property(strong,nonatomic) UITableView *tableView;

@property(strong,nonatomic) NSArray *historyArray;

@end

@implementation ViewController

static NSString *HistoryDateCellID = @"HistoryDateCellId";

- (void)viewDidLoad {

    [super viewDidLoad];

    [self setupTableView];

    [self initJson];

}

#pragma mark - JSON 解析

-(void)initJson{

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"json"];

    NSData *jdata = [[NSData alloc]initWithContentsOfFile:filePath];

    NSDictionary *hisDict = [NSJSONSerialization JSONObjectWithData:jdata options:kNilOptions error:nil];

    self.historyArray = [HistoryDateModel mj_objectArrayWithKeyValuesArray:hisDict[@"data"]];

}

#pragma mark - 设置表格

-(void)setupTableView{

    self.tableView = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];

    for (UIView *subView in self.tableView.subviews) {

        if ([subView isKindOfClass:[UIScrollView class]]) {

            ((UIScrollView *)subView).delaysContentTouches = NO;

        }

    }

    self.tableView.delaysContentTouches = NO;

    self.tableView.delegate = self;

    self.tableView.dataSource = self;

    [self.tableView registerNib:[UINib nibWithNibName:NSStringFromClass([HistoryDateCell class]) bundle:nil] forCellReuseIdentifier:HistoryDateCellID];

    [self.view addSubview:self.tableView];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

    return ;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    HistoryDateCell *cell = [tableView dequeueReusableCellWithIdentifier:HistoryDateCellID];

    cell.historyDate = self.historyArray;

    cell.selectionStyle = UITableViewCellSelectionStyleNone;

    return cell;

}

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{

    return ;

}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    [tableView deselectRowAtIndexPath:indexPath animated:YES];

}

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

@end

然后话折线图的代码都放在自定义cell 的代码里面，具体如下，我这里是对传入的参数进行了分类真正测试的话不会有这个复杂，并且我用的是wkwebview，这个的内存泄露没UIwebview那么严重，所以就用了这个

#import "HistoryDateCell.h"

#import "HistoryDateModel.h"

#import <WebKit/WebKit.h>

#import "TimeTools.h"
