Downloading App update OTA from Amazon Aws s3 iOS

Question

I'm looking to create in app updates, currently my app creates a signed url for my plist file in my Amazon was s3 bucket, I've also created a signed url for my .ipa file and stored that signed url in my plist file, as can be seen below:

URL Call in App:

NSMutableString *downloadURL = [NSMutableString string] ;
[downloadURL appendString:@"itms-services://?action=download-manifest&url="];
[downloadURL appendString:plistURL];
NSString *ipaDownloadString = [NSString stringWithString:downloadURL];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:ipaDownloadString]];

where ipaDownloadString is a signed url appended to item-services://?action etc.

Plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"     "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>items</key>
<array>
    <dict>
        <key>assets</key>
        <array>
            <dict>
                <key>kind</key>
                <string>software-package</string>
                <key>url</key>
                <string>https://bucket_name.s3-eu-west-1.amazonaws.com/ipa_name.ipa?AWSAccessKeyId=xxxxxxxxxxxxx&Expires=1435587320&Signature=xxxxxxxxxxxx</string>
</dict>
            </array>
    <key>metadata</key>
        <dict>
            <key>bundle-identifier</key>
            <string>com.name.DropboxTest</string>
            <key>bundle-version</key>
            <string>1.1</string>
            <key>kind</key>
            <string>software</string>
            <key>title</key>
            <string>Dropbox Test</string>
        </dict>
    </dict>
     </array>
</dict></plist>

The urls are working when you plug them into a browser however, the app won't download the app as it should when the link is clicked.

I have tried url encoding the url in the plist to no avail. The plist has content-type: text/plain the ipa has content-type |: application/octet-stream

I solved this myself, for those who need this information in the future:

The url in the plist file needs to be signed and and the &s in said url need to be encoded in the form &.

I have found the content-type on s3 has no being on the issue at all.

I have included a sample plist:

 <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>

        <key>items</key>
        <array>
            <dict>
 
                <!-- an array of assets to download -->
                <key>assets</key>
                <array>
 
                    <!-- software-package: the ipa to install. -->
                    <dict>
 
                        <!-- required.  the asset kind. -->
                        <key>kind</key>
                        <string>software-package</string>

                        <!-- required.  the URL of the file to download. -->

        </array>
    </dict>
</plist>

I hope this helps someone in the future.

Answer 2

In my case, I replaced & with &

If I use & with & it did not work.
