Summary:
An UIColor instance A isn't equal to the instance B obtained by archiving and unarchiving the instance A.
It happens only on devices with 64bit architecture.

Follows the code snippet :
    UIColor *color = [UIColor colorWithRed:1. green:0.4 blue:0. alpha:1.];
    NSData *colorData = [NSKeyedArchiver archivedDataWithRootObject:color];
    UIColor *color2 = [NSKeyedUnarchiver unarchiveObjectWithData:colorData];
    BOOL isDevice64Bit = sizeof(void*) == 8;
    NSLog(@"is64Bit: %i - isEqual: %i", isDevice64Bit, [color isEqual:color2]);

The isEqual above should always return true, but it does not for devices with 64bit architecture.

Steps to Reproduce:
Create a iOS empty project and paste the following code inside of the "application:didFinishLaunchingWithOptions:" method and run it using iPhone 5s or higher:

    UIColor *color = [UIColor colorWithRed:1. green:0.4 blue:0. alpha:1.];
    NSData *colorData = [NSKeyedArchiver archivedDataWithRootObject:color];
    UIColor *color2 = [NSKeyedUnarchiver unarchiveObjectWithData:colorData];
    BOOL isDevice64Bit = sizeof(void*) == 8;
    NSLog(@"is64Bit: %i - isEqual: %i", isDevice64Bit, [color isEqual:color2]);


Expected Results:
It should always log "is64Bit: 0 - isEqual: 1" or "is64Bit: 1 - isEqual: 1"

Actual Results:
It logs "is64Bit: 0 - isEqual: 1" or "is64Bit: 1 - isEqual: 0"

Version:
iOS 8.1.1

Notes:


Configuration:
64bit devices (iPhone 5s, 6, 6plus, iPad air, mini retina)
