我正在开发一个项目，我必须在iPhone设备照片库中保存捕获的图像 .
我想问一下如何通过代码实现这一点 . 下面我粘贴我的代码： -
- （void）imagePickerController：（UIImagePickerController *）picker didFinishPickingMediaWithInfo：（NSDictionary *）info {
[picker dismissModalViewControllerAnimated:YES];
imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
imgglobal =imageView.image;
NSString *newFilePath = [NSHomeDirectory() stringByAppendingPathComponent: @"~/Users/abc/Library/Application Support/iPhone Simulator/User/Applications/SAVE_IMAGE_TEST1.JPG"];
NSData *imageData = UIImageJPEGRepresentation(imageView.image, 1.0);
NSData *data = imageData;
if (imageData != nil) {
[imageData writeToFile:newFilePath atomically:YES];
}
if ([[NSFileManager defaultManager] createFileAtPath:@"~/Users/abc/Library/Application Support/iPhone Simulator/User/Applications/SAVE_IMAGE_TEST1.JPG" contents:data attributes:nil])
{
UIAlertView *successAlert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Image was successfully saved to the Photo Library." delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
[successAlert show];
[successAlert release];
} else {
UIAlertView *failureAlert = [[UIAlertView alloc] initWithTitle:@"Failure" message:@"Failed to save image to the Photo Library." delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
[failureAlert show];
[failureAlert release];
}
}
但我的应用程序显示失败警报请发送正确的代码将捕获的图像保存到Iphone设备照片库 .
在此先感谢它非常紧急

这是一个单线程（不计算错误处理） . 只需拨打
UIImageWriteToSavedPhotosAlbum()即可 .
