ALSystemUtilities

In order to use the framework you have to open the project in Xcode and then click on Product -> Archive and drag the .embeddedframework file into the project you want to import it.

The project is built using the iOS Universal Framework template (Fake framework) by kstenerud (https://github.com/kstenerud/iOS-Universal-Framework?source=cc).

Overview

You can implement the code to free the memory with the ALSystemUtilities framework. This is the gist URL : https://gist.github.com/andrealufino/7888447

The library provides informations for these purviews :

• battery;
• disk;
• hardware;
• jailbreak;
• localization;
• memory (RAM);
• network;
• processor;
• carrier;
• accessories;

Now I'll explain you what informations are contained for every purview.

Battery

• + (BOOL)batteryFullCharged;
• + (BOOL)inCharge;
• + (BOOL)devicePluggedIntoPower;
• + (UIDeviceBatteryState)batteryState;
• + (CGFloat)batteryLevel;
• + (NSString *)remainingHoursForStandby;
• + (NSString *)remainingHoursFor3gConversation;
• + (NSString *)remainingHoursFor2gConversation;
• + (NSString *)remainingHoursForInternet3g;
• + (NSString *)remainingHoursForInternetWiFi;
• + (NSString *)remainingHoursForVideo;
• + (NSString *)remainingHoursForAudio;

Disk

• + (NSString *)totalDiskSpace;
• + (NSString *)freeDiskSpace;
• + (NSString *)usedDiskSpace;
• + (CGFloat)totalDiskSpaceInBytes;
• + (CGFloat)freeDiskSpaceInBytes;
• + (CGFloat)usedDiskSpaceInBytes;

Hardware

• + (NSString *)deviceModel;
• + (NSString *)deviceName;
• + (NSString *)systemName;
• + (NSString *)systemVersion;
• + (NSInteger)screenWidth;
• + (NSInteger)screenHeight;
• + (CGFloat)brightness;
• + (NSString *)platformType;
• + (NSDate *)bootTime;
• + (BOOL)proximitySensor;
• + (BOOL)multitaskingEnabled;
• + (NSString *)sim;
• + (NSString *)dimensions;
• + (NSString *)weight;
• + (NSString *)displayType;
• + (NSString *)displayDensity;
• + (NSString *)WLAN;
• + (NSString *)bluetooth;
• + (NSString *)cameraPrimary;
• + (NSString *)cameraSecondary;
• + (NSString *)cpu;
• + (NSString *)gpu;
• + (BOOL)siri;
• + (BOOL)touchID;

Jailbreak

• + (BOOL)isJailbroken;

Localization

• + (NSString *)language;
• + (NSString *)timeZone;
• + (NSString *)currencySymbol;
• + (NSString *)currencyCode;
• + (NSString *)country;
• + (NSString *)measurementSystem;

Memory (RAM)

• + (NSInteger)totalMemory;
• + (CGFloat)freeMemory;
• + (CGFloat)usedMemory;
• + (CGFloat)activeMemory;
• + (CGFloat)wiredMemory;
• + (CGFloat)inactiveMemory;

Network

• + (NSString *)currentIPAddress;
• + (BOOL)connectedViaWiFi;
• + (BOOL)connectedVia3G;
• + (NSString *)macAddress;
• + (NSString *)externalIPAddress;
• + (NSString *)cellIPAddress;
• + (NSString *)WiFiNetmaskAddress;
• + (NSString *)WiFiBroadcastAddress;

Processor

• + (NSInteger)processorsNumber;
• + (NSInteger)activeProcessorsNumber;
• + (CGFloat)cpuUsageForApp;
• + (NSArray *)activeProcesses;
• + (NSInteger)numberOfActiveProcesses;

Carrier

• + (NSString *)carrierName;
• + (NSString *)carrierISOCountryCode;
• + (NSString *)carrierMobileCountryCode;
• + (NSString *)carrierMobileNetworkCode;
• + (BOOL)carrierAllowsVOIP;

Accessories

• + (BOOL)accessoriesPluggedIn;
• + (NSInteger)numberOfAccessoriesPluggedIn;
• + (BOOL)isHeadphonesAttached;

So, there are 78 methods to get every kind of information!

All methods are class methods, so you can use the syntax [ALCarrier carrierName]. This make the use of the library very very simple!
