ClipImageDemo

1.實現圓形 方形兩種方式的圖片裁剪,支持自定義裁剪大小,支持自定義圖片縮放比例 2.基于UIImagePickerController,在UIImagePickerControllerDelegate方法中進行調用

直接上使用的關鍵代碼 具體實現請查看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; //支持圓形:CIRCULARCLIP 方形裁剪:SQUARECLIP   默認:圓形裁剪
if(![textField.text isEqualToString:@""])
{
    radius =textField.text.intValue;
    clipView.radius = radius;   //設置 裁剪框的半徑  默認120
}
//    clipView.scaleRation = 2;// 圖片縮放的最大倍數 默認為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
