拍照并将其保存到相册中

问题描述

| 我使用此代码拍照：

-(IBAction) getPhoto:(id) sender {
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;

if((UIButton *) sender == choosePhotoBtn) {
    picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
} else {
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}

[self presentModalViewController:picker animated:YES];

}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediawithInfo:(NSDictionary *)info {
    [picker dismissModalViewControllerAnimated:YES];
    imageView.image = [info objectForKey:@\"UIImagePickerControllerOriginalImage\"];
}

我想知道如何保存我拍到相册的这张照片。     

解决方法

签出《 UIKit函数参考》，使用：

UIImageWriteToSavedPhotosAlbum()

用法：

UIImageWriteToSavedPhotosAlbum(theImage,nil,nil);
