ios - ImageContext 返回扭曲的图像
<p><p>我正在尝试使图像的角变圆，但 ImageContext 中的图像变形了。 </p>
<p>这是我正在采取的步骤:</p>
<pre><code>- (UIImage *)decodeBase64ToImage:(NSString *)strEncodedData
{
NSURL *url = ;
NSData* data = [ initWithContentsOfURL:url];
UIImage* image = [ initWithData:data];
UIImage* croppedImage = ;
return croppedImage;
}
- (UIImage *)makeRoundedImage:(UIImage *) image
{
CGRect frame = CGRectMake(0, 0, image.size.width, image.size.height);
UIGraphicsBeginImageContext(frame.size);
//[ addClip];
;
// Get the image
UIImage *croppedImage = UIGraphicsGetImageFromCurrentImageContext();
// Lets forget about that we were drawing
UIGraphicsEndImageContext();
return croppedImage;
}
</code></pre></p>

<p><p><strong>你可以检查这个方法</strong> </p>
<pre><code>-(UIImage *)roundedImage:(UIImage *) roundImage
radius: (float) radius;
{
CALayer *imageLayer = ;
imageLayer.frame = CGRectMake(0, 0, roundImage.size.width, roundImage.size.height);
imageLayer.contents = (id) roundImage.CGImage;
imageLayer.masksToBounds = YES;
imageLayer.cornerRadius = radius;
UIGraphicsBeginImageContext(roundImage.size);
;
UIImage *finalRoundedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return finalRoundedImage;
}
</code></pre></p>
