这是我保存图像的方式
$csv_path
下面是我用来检索图片的代码,但我得到的是URL而不是图像文件来填充tableview。任何帮助将不胜感激
namespace App\Providers;
use Illuminate\Support\Arr;
use Storage;
use League\Flysystem\Filesystem;
use Aws\S3\S3Client;
use League\Flysystem\AwsS3v3\AwsS3Adapter as S3Adapter;
use Illuminate\Support\ServiceProvider;
class CustomS3Filesystem extends ServiceProvider
{
/**
* Format the given S3 configuration with the default options.
*
* @param array $config
* @return array
*/
protected function formatS3Config(array $config)
{
$config += ['version' => 'latest'];
if ($config['key'] && $config['secret']) {
$config['credentials'] = Arr::only($config, ['key', 'secret']);
}
return $config;
}
/**
* Bootstrap a custom filesystem
*
* @return void
*/
public function boot()
{
Storage::extend('s3_custom', function($app, $config)
{
$s3Config = $this->formatS3Config($config);
return new Filesystem(
new S3Adapter(
new S3Client($s3Config),
$config['bucket'],
null,
[
'CacheControl' => 'max-age=432000'
]
)
);
});
}
public function register()
{
//
}
}

这只是因为您的图片名称无效。使用调试器查找imageUrl
的确切值,我打赌它类似于.../Documents/img
。你想要的更像是.../Documents/Sep-04-2017-12.img
您必须在视图控制器中存储currentFileName
,以便日后可以参考。
此外,您的命名策略非常脆弱。许多图像最终都可以共享一个名称。
如果您有一个装满图片的文件夹,您可以迭代该文件夹以取回img
个文件:
let fileManager = FileManager.default
let documentDirectory = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
let directoryContents = try! fileManager.contentsOfDirectory(at: documentDirectory, includingPropertiesForKeys: nil)
for imageURL in directoryContents where imageURL.pathExtension == "img" {
if let image = UIImage(contentsOfFile; imageURL.path) {
// now do something with your image
} else {
fatalError("Can't create image from file \(imageURL)")
}
}

尝试使用此
func getImage(){
let fileManager = FileManager.default
let imagePAth = (self.getDirectoryPath() as NSString).appendingPathComponent("apple.jpg") // saved image name apple.jpg
if fileManager.fileExists(atPath: imagePAth){
self.lockbackImageview.image = UIImage(contentsOfFile: imagePAth)
}else{
print("No Image")
self.lockbackImageview.image = UIImage.init(named: "1.jpg")
}
}
