最终效果图因为我们的项目未使用pods，所以下面我详情一下手动引入时发现的坑。下面我以Charts 3.0.1版本为例，别问我为什么？由于我们的项目使用的是Swift 3.0，别问我为什么不更新？大佬们，我不敢啊！小弟做不到啊！
手动引入步骤
- 选择基础库下载到本地
- 导入Charts到工程，并设置工程属性
- 增加代码，实现基本效果
- 运行程序，查看效果能否一致
- 修改，修改，修改
详细步骤
Charts地址2-1.将下载下来的Charts.xcodeproj和Source文件保留，其他删除就可
Charts 3.0.12-2.将Charts文件夹拷贝至工程，右键工程，点击Add Files to “project name”，注意只增加Charts.xcodeproj
右键增加Charts到工程
导入Charts.framework3-1.在控制器.m头文件中引入@import Charts;，初始化LineChartView，设置属性
self.lineChartView=[[LineChartView alloc]initWithFrame:CGRectMake(0, 0, self.lineChartBgScroll.width, 200)]; [self.lineChartBgScroll addSubview:self.lineChartView]; //设置折线图形容 self.lineChartView.noDataText=@"暂无数据"; //没数据时显示 self.lineChartView.scaleYEnabled=NO; //启动Y轴缩放 self.lineChartView.scaleXEnabled=NO; //启动X轴缩放 self.lineChartView.doubleTapToZoomEnabled=NO; //取消双击缩放 // 隐藏折线图形容及图例样式 self.lineChartView.chartDescription.enabled = NO; self.lineChartView.dragEnabled=YES; //启动拖拽图标 self.lineChartView.legend.enabled = NO; // 隐藏说明 self.lineChartView.dragDecelerationEnabled=YES; //拖拽后能否有惯性效果 self.lineChartView.dragDecelerationFrictionCoef = 0.9;//拖拽后惯性效果的摩擦系数(0~1),数值越小,惯性越不显著 //设置X轴样式 ChartXAxis *xAxis = self.lineChartView.xAxis; xAxis.enabled = YES; xAxis.axisLineWidth = 1.0/[UIScreen mainScreen].scale;//设置X轴线宽 xAxis.labelPosition = XAxisLabelPositionBottom;//X轴的显示位置，默认是显示在上面的 xAxis.drawGridLinesEnabled = NO;//不绘制网格线 xAxis.drawLabelsEnabled = YES; // xAxis.spaceBetweenLabels = 4;//设置label间隔 xAxis.labelTextColor = rgb(145, 148, 153);//label文字颜色 //设置Y轴样式 self.lineChartView.rightAxis.enabled = NO;//不绘制右边轴 ChartYAxis *leftAxis = self.lineChartView.leftAxis;//获取左边Y轴 leftAxis.labelCount = 6;//Y轴label数量，数值不肯定，假如forceLabelsEnabled等于YES, 则强制绘制制定数量的label, 但是可能不平均 leftAxis.drawGridLinesEnabled = NO;// leftAxis.drawAxisLineEnabled = NO; leftAxis.forceLabelsEnabled = NO;//不强制绘制指定数量的label // leftAxis.showOnlyMinMaxEnabled = NO;//能否只显示最大值和最小值 leftAxis.axisMinimum = 0;//设置Y轴的最小值 leftAxis.drawZeroLineEnabled = YES;//从0开始绘制// leftAxis.axisMaximum = 105;//设置Y轴的最大值 leftAxis.inverted = NO;//能否将Y轴进行上下翻转 leftAxis.axisLineWidth = 1.0/[UIScreen mainScreen].scale;//Y轴线宽 leftAxis.axisLineColor = [UIColor blackColor];//Y轴颜色 leftAxis.valueFormatter = [[RBYAxisFormatter alloc] init];//自己设置格式 leftAxis.labelPosition = YAxisLabelPositionOutsideChart;//label位置 leftAxis.labelTextColor =[UIColor blackColor];//文字颜色 leftAxis.labelFont = [UIFont systemFontOfSize:10.0f];//文字字体3-2.数据返回后增加数据
if (self.dataArray.count == 0) { return; } NSMutableArray *xLables = [NSMutableArray arrayWithCapacity:0]; NSMutableArray *data01Array = [NSMutableArray arrayWithCapacity:0]; NSMutableArray *data02Array = [NSMutableArray arrayWithCapacity:0]; NSMutableArray *data03Array = [NSMutableArray arrayWithCapacity:0]; NSMutableArray *data04Array = [NSMutableArray arrayWithCapacity:0]; int i = 0; for (NSDictionary *dic in self.dataArray) { [xLables addObject:[dic[@"promotetime"] substringFromIndex:5]]; NSString *priceStr = dic[@"priceStr"]; NSArray *priceArray = [priceStr componentsSeparatedByString:@","]; ChartDataEntry *entry1 = [[ChartDataEntry alloc] initWithX:i y:[priceArray.firstObject doubleValue]]; [data01Array addObject:entry1]; ChartDataEntry *entry2 = [[ChartDataEntry alloc] initWithX:i y:[priceArray[1] doubleValue]]; [data02Array addObject:entry2]; ChartDataEntry *entry3 = [[ChartDataEntry alloc] initWithX:i y:[priceArray[2] doubleValue]]; [data03Array addObject:entry3]; ChartDataEntry *entry4 = [[ChartDataEntry alloc] initWithX:i y:[priceArray.lastObject doubleValue]]; [data04Array addObject:entry4]; i++; } // 设置数据格式 self.lineChartView.xAxis.valueFormatter = [[ChartIndexAxisValueFormatter alloc] initWithValues:xLables]; // 设置x轴数据个数 不设置会出现多个重复数据 self.lineChartView.xAxis.labelCount = xLables.count; // 设置x轴数据均匀排列 不设置会出现分布不均匀 self.lineChartView.xAxis.granularity = 1.0; self.lineChartView.xAxis.granularityEnabled = YES; LineChartDataSet *set1 = [[LineChartDataSet alloc] initWithValues:data01Array label:@"第一名"]; set1.axisDependency = AxisDependencyLeft; set1.drawValuesEnabled = YES;//能否在拐点处显示数据 set1.valueTextColor = rgb(255, 153, 170); set1.lineWidth = 1.5; set1.fillAlpha = 1; [set1 setColor:rgb(255, 153, 170)]; set1.fillColor = rgb(255, 153, 170); set1.highlightColor = [UIColor colorWithRed:224/255.0 green:117/255.0 blue:117/255.0 alpha:1.0]; set1.drawCirclesEnabled = NO; set1.drawCircleHoleEnabled = NO; LineChartDataSet *set2 = [[LineChartDataSet alloc] initWithValues:data02Array label:@"第二名"]; set2.axisDependency = AxisDependencyLeft; set2.drawValuesEnabled = YES;//能否在拐点处显示数据 set2.valueTextColor = rgb(179, 204, 255); set2.lineWidth = 1.5; set2.drawCirclesEnabled = NO; set2.fillAlpha = 0.26; [set2 setColor:rgb(179, 204, 255)]; set2.fillColor = [UIColor colorWithRed:51/255.0 green:181/255.0 blue:229/255.0 alpha:1.0]; set2.highlightColor = [UIColor colorWithRed:224/255.0 green:117/255.0 blue:117/255.0 alpha:1.0]; set2.drawCircleHoleEnabled = NO; LineChartDataSet *set3 = [[LineChartDataSet alloc] initWithValues:data03Array label:@"第三名"]; set3.axisDependency = AxisDependencyLeft; set3.drawValuesEnabled = YES;//能否在拐点处显示数据 set3.valueTextColor = rgb(255, 204, 153); set3.lineWidth = 1.5; set3.drawCirclesEnabled = NO; set3.fillAlpha = 0.26; [set3 setColor:rgb(255, 204, 153)]; set3.fillColor = [UIColor colorWithRed:51/255.0 green:181/255.0 blue:229/255.0 alpha:1.0]; set3.highlightColor = [UIColor colorWithRed:224/255.0 green:117/255.0 blue:117/255.0 alpha:1.0]; set3.drawCircleHoleEnabled = NO; LineChartDataSet *set4 = [[LineChartDataSet alloc] initWithValues:data04Array label:@"我"]; set4.axisDependency = AxisDependencyLeft; set4.drawValuesEnabled = YES;//能否在拐点处显示数据 set4.valueTextColor = rgb(28, 188, 66); set4.lineWidth = 1.5; set4.drawCirclesEnabled = NO; set4.fillAlpha = 0.26; [set4 setColor:rgb(28, 188, 66)]; set4.fillColor = [UIColor colorWithRed:51/255.0 green:181/255.0 blue:229/255.0 alpha:1.0]; set4.highlightColor = [UIColor colorWithRed:224/255.0 green:117/255.0 blue:117/255.0 alpha:1.0]; set4.drawCircleHoleEnabled = NO; NSMutableArray *dataSets = [[NSMutableArray alloc] init]; [dataSets addObject:set1]; [dataSets addObject:set2]; [dataSets addObject:set3]; [dataSets addObject:set4]; LineChartData *data = [[LineChartData alloc] initWithDataSets:dataSets]; [data setValueFont:[UIFont systemFontOfSize:10]]; // 设置y轴值所有点的数据格式 [data setValueFormatter:[[RBYPointFormatter alloc] init]]; // 设置x轴左右间距 self.lineChartView.xAxis.axisMinimum = data.xMin - 0.8; self.lineChartView.xAxis.axisMaximum = data.xMax + 0.8; self.lineChartView.data = data; // 设置显示最大最小范围 超过可滑动 即设置滑动 [self.lineChartView setVisibleXRangeWithMinXRange:1 maxXRange:8]; // 显示所有线条 [self.lineChartView animateWithXAxisDuration:0.5];3-3.格式化x轴数据、y轴数据、y轴折线点值数据，创立model类，继承NSObject，再新建一个类，分别遵守IChartAxisValueFormatter和IChartValueFormatter
.h// y轴点数据格式化@interface RBYPointFormatter : NSObject <IChartValueFormatter>@end// y轴数据格式化@interface RBYAxisFormatter : NSObject <IChartAxisValueFormatter>@end设置数据格式
.m@implementation RBYPointFormatter- (NSString *)stringForValue:(double)value entry:(ChartDataEntry *)entry dataSetIndex:(NSInteger)dataSetIndex viewPortHandler:(ChartViewPortHandler *)viewPortHandler { return [NSString stringWithFormat:@"%.2f",value];}@end@implementation RBYAxisFormatter- (NSString *)stringForValue:(double)value axis:(ChartAxisBase *)axis { return [NSString stringWithFormat:@"￥%.2f",value];}@end使用leftAxis.valueFormatter = [[RBYAxisFormatter alloc] init];//自己设置格式
最终效果图1.均匀排布、左右间距和滑动设置
self.lineChartView.xAxis.labelCount = xLables.count; // 设置x轴数据均匀排列 不设置会出现分布不均匀 self.lineChartView.xAxis.granularity = 1.0; // 设置x轴左右间距 self.lineChartView.xAxis.axisMinimum = data.xMin - 0.8; self.lineChartView.xAxis.axisMaximum = data.xMax + 0.8; self.lineChartView.data = data; // 设置显示最大最小范围 超过可滑动 即设置滑动 [self.lineChartView setVisibleXRangeWithMinXRange:1 maxXRange:8];2.假如这时候你发现你的工程Scheme运行的设施多出了My Mac和Build Only decices多出了Generic tcOS device
多平台Scheme处理方案：
因为我是导入Charts库后出现的该问题，所以我进到Charts的工程设置
1.Build Setting->TARGET->Architectures->Base SDK，将macOS修改为iOS
修改Base SDK2.Build Setting->TARGET->Architectures->Supported Plateforms，将tvOS修改为iOS
修改Supported Plateforms网上的其余处理方案（处理不能显示真机或者模拟器，只显示My Mac）
关闭Xcode，找到该工程项目目录，找到该项目的***.xcodeproj 文件，而后右键点击选择“显示包内容”；包内容中会显示以下三项：project.pbxproj ，project.xcworkspace ，xcuserdata ，xcshareddata（不能删除这个，多人开发会用到）接着选择“xcuserdata”这个文件夹，将其整个移到废纸篓，重新打开你的项目，则可使用真机或者模拟器；假如上述方法没有用,在可以再Build Setting->TARGET->Architectures->Base SDK版本就可。
修改之后不显示My Mac
