Example for testing
The example app blow is intended to be used as part of the testing to be performed when this feature is being accepted. Some changes will need to be made to the code depending on how this feature is implemented.
var win = Ti.UI.createWindow({
backgroundColor: 'blue',
layout: 'vertical'
});
var testFile;
var label = Ti.UI.createLabel({
top: 10,
height: 100,
width: 300,
backgroundColor: "green",
text: "Read the text file already!"
});
win.add(label);
var tfield = Ti.UI.createTextField({
top: 10,
height: 40,
width: 200,
borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED,
value: "text written via write()"
});
tfield.addEventListener('return', function(e){
tfield.blur();
});
win.addEventListener('click', function(e){
tfield.blur();
});
win.add(tfield);
var createButton = Ti.UI.createButton({
top: 20,
height: 50,
width: 200,
title: "Create File"
});
createButton.addEventListener('click', function(e){
testFile = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'text.txt');
});
win.add(createButton);
var writeButton = Ti.UI.createButton({
top: 20,
height: 50,
width: 200,
title: "Write File"
});
writeButton.addEventListener('click', function(e){
Ti.API.info('text.txt exists? ' + testFile.exists());
Ti.API.info('text.txt size: ' + testFile.size + ' bytes');
if(!testFile.write(tfield.value)) {
Ti.API.info("could not write string to file.");
}
});
win.add(writeButton);
var readButton = Ti.UI.createButton({
top: 20,
height: 50,
width: 200,
title: "Read File"
});
readButton.addEventListener('click', function(e){
Ti.API.info('text.txt exists? ' + testFile.exists());
Ti.API.info('text.txt size: ' + testFile.size + ' bytes');
var text = testFile.read().text;
Ti.API.info('#### Text of testFile: ['+text+']');
label.text = text;
});
win.add(readButton);
var deleteButton = Ti.UI.createButton({
top: 20,
height: 50,
width: 200,
title: "Delete File"
});
deleteButton.addEventListener('click', function(e){
testFile.deleteFile();
});
win.add(deleteButton);
win.open();
