[Objective-C] 如何從NSString轉NSURL

常用到的NSString檔案路徑要轉NSURL 

NSString *filePath=[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"360_theta.JPG"];

    

    NSLog(@"file path: %@",filePath);

    

    NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];

    NSLog(@"file url: %@",[fileURL filePathURL]);

// 輸出如下

//    file url: file:///var/containers/Bundle/Application/091D1094-B023-42B1-9B5D-31D9C76678D6/fblive.app/360_theta.JPG
