KRDeviceType

KRDeviceType is a simple class written in Swift that helps to get type of iOS device for layout purposes.

Installation

####CocoaPods

Just add pod 'KRDeviceType' to your Podfile and run pod install in Terminal from your project folder.

Write import KRDeviceType in files where you need to use KRDeviceType.

How to use

KRDeviceType should be used only for layout purposes. For example, sometimes you need set different constraints for old devices which screen size doesn't meet requirements of your design project. KRDeviceType class get info about screen size and use this information to check current device type. Don't use this class for accurate detecting of your device type (for example you may wish to check if you device is accurate iPhone 5s);

Operators ==, <=, >=

To get current device type you can use == operator of KRDevice with DeviceType enumeration.

For example, if you want to check is current device is iPhone you can do it in next way:

if KRDeviceType() == .iPhone {
    // Perform appropiate operations
}

If you wish to check if current device is 4.7 inches iPhone (iPhone 6 or iPhone 6s or iPhone 7):

if KRDeviceType() == .iPhone6 {
    // Perform appropiate operations
}

You can also use equalOrLess("<=") or equalOrGreater(">=") equality operators:

if KRDeviceType() <= .iPhone5 {   //iPhone 5/5s/SE of iPhone 4s
// Perform appropiate operations (for example, set up constraints for those old devices)
}

if KRDeviceType() >= .iPhone6Plus {   //iPhone 6 Plus/ 6s Plus/ 7 Plus or greater
// Perform appropiate operations for 3x scale devices (not only iPhone 6Plus, but possibly future devices with higher resolutions screens)
}

Static variables

To get current device type you can use one of next static variables:

static var isiPhone : Bool // return true if device is iPhone
static var isiPad : Bool // return true if device is iPad

// get device type by checking its screen size
static var isiPhone4s : Bool // iPhone 4s or iPhone 4
static var isiPhone5 : Bool // iPhone 5 or iPhone 5s or iPhone SE
static var isiPhone6 : Bool // iPhone 6 or iPhone 6s or iPhone 7
static var isiPhone6Plus : Bool // iPhone 6 Plus or iPhone 6s Plus or iPhone 7s Plus

static var isiPad2 : Bool // iPad 2
static var isiPadMiniOrAir : Bool  // iPad Mini or iPad Retina or iPad Air or iPad Air 2 or iPad Pro 9.7
static var isiPadPro : Bool // iPad Pro 12.9

For example:

if KRDeviceType.isiPad {
    // Perform appropiate operations
} else { // iPhone
    // Perform appropiate operations
}

Requirements

• iOS 8.0 and above
