使用AssetPath创建NSURL [英] Create NSURL using AssetPath

问题描述

使用UIImagePickerController，我可以获得像 assets-library：//asset/asset.MOV？id = 2A2CE6C9-C178-4395-977B-E6F159BF6D5E& ext这样的媒体的资产路径= MOV 。

Using UIImagePickerController, I'm able to get the Asset Path for a Media like assets-library://asset/asset.MOV?id=2A2CE6C9-C178-4395-977B-E6F159BF6D5E&ext=MOV.

NSURL *instagramURL = [NSURL URLWithString:[NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",[referenceURL absoluteString], strInstagramCaption]];

现在，我想将此资产路径转换为NSURL以将其传递到以下代码块：

Now, I want to convert this Asset Path into NSURL to pass it into following code block :

if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
    [[UIApplication sharedApplication] openURL:instagramURL];
}

推荐答案

这是如何将资产路径转换为有效 NSUrl ： -

This is the way how you should convert asset path to valid NSUrl:-

NSURL *instagramURL = [NSURL URLWithString:[[NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",[assetURL absoluteString],caption]stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
        [[UIApplication sharedApplication] openURL:instagramURL];
    }
