ClipImageDemo
1.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 2.基于UIImagePickerController,在UIImagePickerControllerDelegate方法中进行调用
直接上使用的关键代码 具体实现请查看YSHYClipViewController.m 文件
pragma mark - imagePickerControllerDelegate
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)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 = 2;// 图片缩放的最大倍数 默认为3 [picker pushViewController:clipView animated:YES]; }pragma mark - ClipViewControllerDelegate
-(void)ClipViewController:(YSHYClipViewController *)clipViewController FinishClipImage:(UIImage *)editImage { [clipViewController dismissViewControllerAnimated:YES completion:^{ [btn setImage:editImage forState:UIControlStateNormal]; }];; }下面是演示效果
