UIImageview 在获取图像后在静态 table 视图单元格中不保留其圆形

Question

我想在图像视图中设置从画廊和相机拍摄的图像，该图像视图是圆形的 shape.But 当我将图像设置到图像视图时，图像视图的形状会发生变化。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];

//make imageview round
imageView.layer.cornerRadius = imageView.frame.size.width / 2;
imageView.clipsToBounds = YES;

UIImage *resizedImage=[Services resizeImage:image];
imageView.contentMode = UIViewContentModeScaleAspectFit;

imageView.image=resizedImage;
[self dismissViewControllerAnimated:true completion:nil];

提前致谢

Answer 1

您也可以反其道而行之：将图片裁剪成圆形，然后将其添加到方形视图中：

CALayer *imageLayer = image.layer;
[imageLayer setCornerRadius:image.frame.size.width/2];
[imageLayer setBorderWidth:1];
[imageLayer setMasksToBounds:YES];
imageLayer.borderColor = (__bridge CGColorRef _Nullable)([UIColor clearColor]);

Answer 2

首先确保您的 imageView 宽高比为 1:1

设置图片大小后设置imageView的cornerRadius

Answer 3

将图像视图框架设置为正方形，然后将圆角半径设置为 width.See 这些线的一半 -

 userimage.layer.borderWidth = 3.0
    userimage.clipsToBounds = true
    userimage.layer.cornerRadius = userimage.frame.size.width / 2;
    userimage.layer.borderColor = UIColor.orangeColor().CGColor

此处用户图片尺寸为50*50

Answer 4

您似乎选择了 "tall" 图片。替换

imageView.contentMode = UIViewContentModeScaleAspectFit;

有

imageView.contentMode = UIViewContentModeScaleAspectFill;

以便它覆盖整个区域，您将能够看到它是圆形的。
