Question

在我的 iPhone应用中，添加了照片选项，我添加了照片from library as well as captured images ..

当我打开图像选择器添加/捕获图像时，它只显示重拍和放大使用照片。

当我点击使用时，它显示为图像视图中的图像

但 i need to display my selected crop, 就像在iphone的联系人应用中添加照片一样

我设置了 self.imagePickerController.allowsEditing = YES;

但是每当我想要编辑图像时，我都需要取回原始图像，而不是图像选择器中的缩放/裁剪图像再次编辑

你必须将UIImagePickerController的allowEditing设置为YES，试试以下内容：

- (IBAction)takePicture:(id)sender {
UIImagePickerController *imagePicer = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
    [imagePicer setSourceType:UIImagePickerControllerSourceTypeCamera];
} else {
    [imagePicer setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}

// This will sets the editing mode after taking of picking image from image picker

[imagePicer setAllowsEditing:YES];
[imagePicer setDelegate:self];

//place image picker on the screen
[self presentViewController:imagePicer animated:YES completion:nil];
}

如果您想使用编辑后的图像，请将“UIImagePickerControllerOriginalImage”更改为“UIImagePickerControllerEditedImage”，就是这样!!
