核心情節 - 反轉劇情和標籤

我有一個問題，顯示正確的情節。我使用了RealTimePlot的一些代碼（http://code.google.com/p/core-plot/source/browse/examples/CorePlotGallery/src/plots/RealTimePlot.m）。我不知道爲什麼情節會逆轉。有照片顯示問題。核心情節 - 反轉劇情和標籤

iOS的應用CPTGraphHostingView翻轉變換到託管圖，從而核心情節可以分享繪畫的iOS和Mac之間的代碼。確保託管視圖及其所有超級視圖都使用其默認轉換。

非常感謝。核心情節圖被託管在CPTGraphHostingView中。我更改爲UIView，現在可以。也許你能幫助我用實時數據提供令人耳目一新的情節嗎？有http://stackoverflow.com/questions/11869179/core-plot-realtime-plot-does-not-automatically-refresh – syntagma 2012-08-09 07:39:18

嘗試只是增加hostingView到self.view之前添加

[hostingView setTransform:CGAffineTransformMakeScale(1,-1)];

。

我使用iOS7的Xcode 5.0，這解決了這個問題。
