我试图在我的应用程序中拍摄照片并将它们保存到具有两个日期的路径(以指定拍摄照片的时间)。在应用程序内拍摄照片保存
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image;
image = [info objectForKey:UIImagePickerControllerOriginalImage];
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil); //save to photo album
NSString *pathString = [NSString stringWithFormat:@"Photos/%@/%@.png",timeStarted,[NSDate date]]; //create path
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:pathString];
//write the files!
[UIImagePNGRepresentation(image) writeToFile:savePath atomically:YES];
}
当我检查的文件夹@"Photos/%@",timeStarted
它显示为空。我究竟做错了什么?
编辑:
这里是我的测试目的的新代码:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//Create the image and save it to the photo album
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
//Create the directory and add the file name to it
NSString *fileName = @"Test.png";
NSString *directory = [NSHomeDirectory() stringByAppendingPathComponent:@"Photos"];
NSString *fullPath = [directory stringByAppendingPathComponent:fileName];
NSLog(@"Full path: %@", fullPath);
//Save "image" to the file path
[UIImagePNGRepresentation(image) writeToFile:fullPath atomically:YES];
//START CHECKING : Log to check if anything was saved
NSError *error;
NSFileManager *fileMgr = [NSFileManager defaultManager];
NSLog(@"Photos directory: %@", [fileMgr contentsOfDirectoryAtPath:directory error:&error]);
//END CHECKING
[camera dismissModalViewControllerAnimated:YES];
}
而且我NSLog
写着:
[640:707] Full path: /var/mobile/Applications/3EEDBD68-5496-458D-9EF0-062746847C83/Photos/Test.png
[640:707] Photos directory: (null)
你是否成功将该图片保存到Photo Album? – beryllium
是的,它可以按照预期保存到相册中。 – Baub
