Settings

Settings is a class that allows you to work immediately with all local storage systems in a simple and convenient wrapper.

This library works on many projects such as Mubert, Morse, etc. Top of App Store.

Under the hood, work with NSUserDefaults (locally and with AppGroups), NSUbiquitousKeyValueStore, NSKeychain with Share.

Sample 1:

Save and load "Test" string to key with "TestKey" name this sample for local settings on current application

Objective-C

In app1 on user iphone

Settings.application[@"TestKey"] = @"Test";

In app1 on user iphone

NSString *s = Settings.application[@"TestKey"];

Swift

In app1 on user iphone

Settings.application["TestKey"] = "Test"

In app1 on user iphone

let s = Settings.application["TestKey"]

Sample 2:

Save and load "Test" string to key with "TestKey" name this sample for local settings between one or more applications

Go to Capability -> App Groups and Add new (group.com.application.test)

Objective-C

In app1 on user iphone

Settings.device[@"TestKey"] = @"Test";

In app2 OR app1 extention user iphone

Settings.deviceAppGroup = @"group.com.application.test";
NSString *s = Settings.device[@"TestKey"];

Swift

In app1 on user iphone

Settings.device["TestKey"] = "Test"

In app2 OR app1 extention user iphone

Settings.deviceAppGroup = "group.com.application.test"
let s = Settings.device["TestKey"]

Sample 3:

Save and load "Test" string to key with "TestKey" name this sample for global settings between one or more user devices and current application (sync with iCloud)

Capability -> iCloud -> Enable Key-Value storage

This action add string "com.apple.developer.ubiquity-kvstore-identifier" to entitlements project file "iCloud Key-Value Store" value for this key is "$(TeamIdentifierPrefix)$(CFBundleIdentifier)" sample somthing this: "9T111111W8.myOrganization.myProducName"

Objective-C

In app1 on user iphone

Settings.all[@"TestKey"] = @"Test";

In app1 on user ipad

NSString *s = Settings.all[@"TestKey"];

Swift

In app1 on user iphone

Settings.all["TestKey"] = "Test"

In app1 on user ipad

let s = Settings.all["TestKey"]

Sample 4:

Save and load "Test" string to key with "TestKey" name this sample for global settings between one or more user devices and between one or more application (sync with iCloud)

Capability -> iCloud -> Enable Key-Value storage

This action add string "com.apple.developer.ubiquity-kvstore-identifier" to entitlements project file "iCloud Key-Value Store" value for this key is "$(TeamIdentifierPrefix)$(CFBundleIdentifier)" sample somthing this id: "9T111111W8.myOrganization.myProducName"

Objective-C

In app1 on user iphone

NSString *idApp1 = Settings.deviceGroupId;
Settings.all[@"TestKey"] = @"Test";

In app2 on user ipad Add Capability -> iCloud -> Enable Key-Value storage Replace in entitlements id to (9T111111W8.myOrganization.myProducName)

NSString *idApp2 = Settings.deviceGroupId; // idApp1 == idApp2
NSString *s = Settings.all[@"TestKey"];

Swift

In app1 on user iphone

let idApp1 = Settings.deviceGroupId;
Settings.all["TestKey"] = "Test"

In app2 on user ipad Add Capability -> iCloud -> Enable Key-Value storage Replace in entitlements id to (9T111111W8.myOrganization.myProducName)

let idApp2 = Settings.deviceGroupId // idApp1 == idApp2
let s = Settings.all["TestKey"]

Sample 5:

Save and load "Test" string to key with "TestKey" name this sample for local keychain without iCloud sync

Objective-C

In app1 on user iphone

Settings.keychainLocal[@"TestKey"] = @"Test";

In app1 on user ipad

NSString *s = Settings.keychainLocal[@"TestKey"];

Swift

In app1 on user iphone

Settings.keychainLocal["TestKey"] = "Test"

In app1 on user ipad

let s = Settings.keychainLocal["TestKey"]

Sample 6:

Save and load "Test" string to key with "TestKey" name this sample for global keychain on all user devices with iCloud sync

Capability -> Keychain Sharing

Objective-C

In app1 on user iphone

Settings.keychain[@"TestKey"] = @"Test";

In app1 on user ipad

NSString *s = Settings.keychain[@"TestKey"];

Swift

In app1 on user iphone

Settings.keychain["TestKey"] = "Test"

In app1 on user ipad

let s = Settings.keychain["TestKey"]

Sample 7:

Save and load "Test" string to key with "TestKey" name this sample for global keychain on all user devices between applications with iCloud sync

Capability -> Keychain Sharing -> Add new group (my.testingKeychain)

Objective-C

In app1 on user iphone

Settings.keychainShare[@"TestKey"] = @"Test";

In app2 on user ipad Add Capability -> Keychain Sharing -> Add new group (my.testingKeychain) or Add Capability -> Keychain Sharing and add new group over code

Settings.keychainGroupId = @"my.testingKeychain";

Then read value

NSString *s = Settings.keychainShare[@"TestKey"];

Swift

In app1 on user iphone

Settings.keychainShare["TestKey"] = "Test"

In app2 on user ipad Add Capability -> Keychain Sharing -> Add new group (my.testingKeychain) or Add Capability -> Keychain Sharing and add new group over code

Settings.keychainGroupId = "my.testingKeychain"

Then read value

let s = Settings.keychainShare["TestKey"]
