YSHYClipImageDemo
图片裁剪
基于imagePickerController 实现圆形 方形两种方式的图片裁剪,支持自定义裁剪大小,支持自定义图片缩放比例
pragma mark - imagePickerControllerDelegate
-(void)imagePickerController:(UIImagePickerController )picker didFinishPickingMediaWithInfo:(NSDictionary<NSString ,id> *)info
{
UIImage * image = info[@'UIImagePickerControllerOriginalImage'];
YSHYClipViewController * clipView = [[YSHYClipViewController alloc]initWithImage:image];
clipView.delegate = self;
clipView.clipType = clipType; //支持圆形:CIRCULARCLIP 方形裁剪:SQUARECLIP 默认:圆形裁剪
if(![textField.text isEqualToString:@''])
{
radius =textField.text.intValue;
clipView.radius = radius; //设置 裁剪框的半径 默认120
}
// clipView.scaleRation = 5;// 图片缩放的最大倍数 默认为10
[picker pushViewController:clipView animated:YES];
}
pragma mark - ClipViewControllerDelegate
-(void)ClipViewController:(YSHYClipViewController )clipViewController FinishClipImage:(UIImage )editImage
{
[clipViewController dismissViewControllerAnimated:YES completion:^{
[btn setImage:editImage forState:UIControlStateNormal];
}];;
