Description

On the iPhone, Titanium.Filesystem.File.write always returns false when writing binary data to files. It works correctly for text data. (There doesn't seem to be a problem on Android.) 
var appDirName = Titanium.Filesystem.applicationDataDirectory;
var txtFile = Titanium.Filesystem.getFile(appDirName, 'foobar.txt');
var binFile = Titanium.Filesystem.getFile(appDirName, 'foobar.bin');

var text = "Sudo make me a sandwich.";

if (!txtFile.exists()) {
    Titanium.API.debug("File " + txtFile.name + " does not exist yet.");
}

if (!binFile.exists()) {
    Titanium.API.debug("File " + binFile.name + " does not exist yet.");
}

if (txtFile.write(text)) {
    Titanium.API.debug("I successfully wrote text to the file.");
} else {
    Titanium.API.debug("I was not able to write text to the file. Oh no!");
}

var blob = Titanium.Utils.base64decode(text); // make some bin data

if (binFile.write(blob)) {
    Titanium.API.debug("I successfully wrote a blob to the file.");
} else {
    Titanium.API.debug("I was not able to write a blob to the file. Oh no!");
}

// Do they exist now?
if (txtFile.exists()) {
    Titanium.API.debug(txtFile.name + " exists, contents: " + txtFile.read());
}

if (binFile.exists()) {
    // Note: Titanium.Filesystem.File.size attribute not mentioned in the API docs
    Titanium.API.debug(binFile.name + " exists, size: " + binFile.size);
}

iPhone:

[DEBUG] File foobar.txt does not exist yet.
[DEBUG] File foobar.bin does not exist yet.
[DEBUG] I successfully wrote text to the file.
[DEBUG] I was not able to write a blob to the file. Oh no!
[DEBUG] foobar.txt exists, contents: Sudo make me a sandwich.
[DEBUG] foobar.bin exists, size: 15

Android:

    I confirmed this running 1.4.1 on iOS 4.

  2. Wilson Luu 2011-11-03 Bug is still valid, occurs in: TiMOB sdk version: 1.7.2, 1.8.0.v20111103144656 Studio version: 1.0.7.201111022004 OS version: Mac OS X Lion Devices tested on: ipod 4.0.2, iphone 5.0
  3. Owen Borseth 2012-02-17 Still a bug as of today with the latest SDK
  4. Stephen Tramer 2012-07-25 Still valid SDK 2.2.0.f9e938d
  5. Junaid Younus 2012-08-16 Still reproducible using TiSDK 2.2.0v20120816015712 on the iOS simulator.
  6. Hans Joachim 2013-02-06 I can confirm this bug. But why has it priority "Medium" only?
  7. Shak Hossain 2014-02-11 This issue can't reproduced with TISDK 3.2 or higher. Therefore, marking is resolved.
  8. Paras Mishra 2014-03-10 Ti.File.write(binary) returns true, tested using the above code, hence closing the issue Verified the fix on: Device : iPhone 5s , iOS version : 7.1 SDK: 3.2.2.v20140221161255 CLI version : 3.2.1 OS : MAC OSX 10.9 Alloy: 1.3.1 ACS: 1.0.14 npm:1.3.2 Appcelerator Studio, build: 3.2.2.201402280732 titanium-code-processor: 1.1.0 XCode : 5.1 Beta 5
