在图像视图上应用旋转后图像变得模糊不清并拧紧 [英] image coming blurred and screwed after applying rotation on image view

问题描述

我陷入一个奇怪的问题， 我有一个图像视图，该视图必须以大约5度的角度显示.为此，我将UIImageView旋转到5度，但是UIImageView中的图像不像转换前那样正确.

I am stuck with a strange problem that, I have a image view which has to shown at some angle approx 5 degree.For that I rotate my UIImageView to 5 degree but the image in UIImageView not coming proper as it was before transformation.

For more understanding see images

您可以看到第二张图像看起来像是从角落剪掉的，并且看起来也有些模糊.

You can see the second image is looking like clipped from corners and looks some blur also.

我的旋转代码:-

myimageView.transform = CGAffineTransformMakeRotation(radians(5));

请建议我如何解决此问题.

Please suggest me how to solve this problem.

谢谢.

推荐答案

您是否尝试过使用CGContextRotateCTM(context, radians);和[sourceImage drawInRect:rect];?
