코어 플롯이 선을 그릴 수 없습니다

Question

Core Plot 라이브러리에 표시된 예제를 기반으로 프로젝트에서 다시 구현하려고했습니다.

y axis을 업데이트하고 심볼을 추가하고 라벨을 그릴 수 있습니다. 그러나 나는 그 라인을 완전히 그릴 수 없습니다.

CPTMutableLineStyle 목적은 내 그래프에 선 스타일을 추가하는 방법입니다 정확하게는 instantied 올바르게 CPTGraph 객체에 살고 있고하는 것 같지만 그래프 여기

에 렌더링되지 않습니다

CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle]; // [dataSourceLinePlot.dataLineStyle mutableCopy]; 
lineStyle.lineWidth    = 3.0; 
lineStyle.lineColor    = [CPTColor greenColor]; 
dataSourceLinePlot.dataLineStyle = lineStyle; 

다음은 전체 클래스 코드입니다.

#import "TUTSimpleScatterPlot.h"

아이디어가 있으십니까? 팁? 해킹? 내 프로젝트에서

UPDATE 1

나는 도서관의 1.2 버전을 사용했다. 회귀하려고 시도한 후 1.0 버전과 줄이 표시됩니다. 마지막 버전에서 작업하도록 프로젝트를 변환하는 방법에 대한 아이디어가 있습니까? pod 'CorePlot', '~> 1.2'에 pod 'CorePlot'에서 Podfile 변경

는 UPDATE 2 *

다른 것 같다. 내 라인을 제대로 그려 ...

Answer 1

이 방법

pod 'CorePlot' 

또는

pod 'CorePlot', '~> 1.2' 

그런 다음 pod install

을 실행하여 libaries를 다시 설치이 방법에 의해 cocoapods를 사용하여 차이가 보인다

이제 프로젝트에서 선을 그릴 수 있습니다.
