ios - 有没有什么好例子可以让IOS获取无剪辑的图片？

Question

默认情况下，当我们从 ios 相册中获取图像时，它总是会被剪切。

而如果我们使用 UIImagePickerControllerOriginalImage，那么它太大了。

(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage*temp =[info objectForKey:UIImagePickerControllerEditedImage];
}

有没有什么好的方法来编辑图像而不剪裁它的范围？

Answer 1

也许是这样的...

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage*temp =[info objectForKey: UIImagePickerControllerOriginalImage];
    CGSize newSize = CGSizeMake("WIDTH", "HEIGHT");  <---- SET YOUR VALUES
    UIGraphicsBeginImageContext(newSize);
    [temp drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
    UIImage* smaller = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

}
