``javascript
// Require the library...
var UserDefaults = require('react-native-userdefaults-ios');
`

#### Writing to standardUserDefaults
`javascript
//Set an Array...
var arr = ['1', '2', '3'];
UserDefaults.setArrayForKey(arr, 'keyForMyArray')
.then(result => {
console.log(result);
});

// Set a String...
UserDefaults.setStringForKey('myString', 'keyForMyString')
.then(result => {
console.log(result);
});

//Set an Object...
var obj = {
name: 'Dave'
};
UserDefaults.setObjectForKey(obj, 'keyForMyObject')
.then(result => {
console.log(result);
});

//Set a boolean value...
UserDefaults.setBoolForKey(true, 'keyForMyBool')
.then(result => {
console.log(result);
});

//Remove an item (works for any type)...
UserDefaults.removeItemForKey('keyOfItemToRemove')
.then(result => {
console.log(result);
});
`

#### Reading from standardUserDefaults
`javascript
// Get an array for a given key...
UserDefaults.arrayForKey('keyForMyArray')
.then(array => {
//Do something with the returned array...
array.forEach(item => {
console.log(item);
});
});

// Get a string for a given key...
UserDefaults.stringForKey('keyForMyString')
.then(string => {
//Do something with the returned string...
console.log(string);
});

// Get an object for a given key...
UserDefaults.objectForKey('keyForMyObject')
.then(obj => {
//Do something with the returned object...
console.log(obj);
});

// Get a boolean value for a given key...
UserDefaults.boolForKey('keyForMyBool')
.then(bool => {
//Do something with the returned boolean value...
console.log(bool);
});
