裁剪图像不适用于UIImagePickerController setAllowsEditing：YES

Question

我正在使用UIImagePickerController来允许用户选择一张图片并将其作为个人资料图片。问题是＆＃34; setAllowsEditing：YES;＆＃34;似乎不起作用。裁剪系统出现了问题，但当你裁剪并按下时，选择＆＃34;图像显示未剪切。我在这里环顾四周，但我似乎无法找到一个好的答案。有什么想法吗？

以下是代码：

@implementation ViewController

- (IBAction)chooseImage:(id)sender {

self.imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.delegate = self;
[self.imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[self presentViewController:self.imagePicker animated:YES completion:nil];
[self.imagePicker setAllowsEditing:YES];

}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

self.chosenImage = info [UIImagePickerControllerOriginalImage];
[self.avatar setImage:self.chosenImage];
[self dismissViewControllerAnimated:YES completion:nil];

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

[self dismissViewControllerAnimated:YES completion:nil];

}

Answer 1

因为您正在获取未编辑的原始图像。您需要捕获已编辑的图像。

Edited Image (use this)
 self.chosenImage = info [UIImagePickerControllerEditedImage];

Orginal Image (not this)
self.chosenImage = info [UIImagePickerControllerOriginalImage];

Answer 2

使用UIImagePickerControllerEditedImage代替UIImagePickerControllerOriginalImage。
