ios - NSMutableArray中的多个图像

我将相机中的图像保存在NSMutableArray中。当我添加一张图片时，该图片将添加到数组中。但是，问题是当我拍摄另一张照片时，第一张照片被第二张照片代替。我想保存相机拍摄的所有照片。

- (IBAction)takePhoto {
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;

    [self presentViewController:picker animated:YES completion:NULL];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *cameraImage = info[UIImagePickerControllerEditedImage];
    self.tempView.image = cameraImage;
    camImages = [NSMutableArray arrayWithCapacity:10];
    [camImages addObject:self.tempView.image];
    //self.chosenImages=camImages;
    NSLog(@"the image is=%@",camImages);
    [picker dismissViewControllerAnimated:YES completion:NULL];
}

最佳答案

带走camImages = [NSMutableArray arrayWithCapacity:10];并将其放在viewDidLoad中。

编辑：使用此代替：

UIImage *cameraImage = info[UIImagePickerControllerEditedImage];
self.tempView.image = cameraImage;

if(!camImages)camImages = [[NSMutableArray alloc]init];

camImages = [NSMutableArray arrayWithCapacity:10];
[camImages addObject:self.tempView.image];
//self.chosenImages=camImages;
NSLog(@"the image is=%@",camImages);
[picker dismissViewControllerAnimated:YES completion:NULL];
