[iPhone] Check iOS device type/ device family

Reference from : http://www.cocos2d-iphone.org/forum/topic/8233

To get the device family for iPhone or iPad or iPod touch, use UIDevice is not enough, it cannot get the really device type. Need to use sysctlbyname() for more information.

/////////////////////////////////////////////////////////////////////////////////////

In DeviceHardware.h file

// Predefine for different devices
#define IPHONE_1G @"iPhone1,1"
#define IPHONE_3G @"iPhone1,2"
#define IPHONE_3GS @"iPhone2,1"
#define IPHONE_4 @"iPhone3,1"
#define IPAD @"iPad1,1"
#define IPOD_TOUCH_1G @"iPod1,1"
#define IPOD_TOUCH_2G @"iPod2,1"
#define IPOD_TOUCH_3G @"iPod3,1"
#define I386 @"Simulator"


@interface DeviceHardware : NSObject


+ (NSString *) platform;

/////////////////////////////////////////////////////////////////////////////////////

In DeviceHardware.m

#import "DeviceHardware.h"
#include
#include


@implementation DeviceHardware

+ (NSString *) platform {

size_t size;

sysctlbyname("hw.machine", NULL, &size, NULL, 0);

char *machine = malloc(size);

sysctlbyname("hw.machine", machine, &size, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
free(machine);

return platform;
}


/////////////////////////////////////////////////////////////////////////////////////

Make a little change from the original one. With predefinition, it might be easier to use. If anyone has better solution, please feel free to let me know!

[iPhone] iOS Data Stors Guidelines

1. Only documents and other data that is user-generated, or that cannot otherwise be recreated by your application, should be stored in the /Documents directory and will be automatically backed up by iCloud.

2. Data that can be downloaded again or regenerated should be stored in the /Library/Caches directory. Examples of files you should put in the Caches directory include database cache files and downloadable content, such as that used by magazine, newspaper, and map applications.

3. Data that is used only temporarily should be stored in the /tmp directory. Although these files are not backed up to iCloud, remember to delete those files when you are done with them so that they do not continue to consume space on the user’s device.


Well, based on this, i guess lots of developers using "example" have to update their apps!

[iPhone] Based on iCloud, need to change the data storage directory

iOS data storage guideline :
https://developer.apple.com/icloud/documentation/data-storage/

Problem :
Since iCloud will sync the data in 'Documents' directory, we need to change the data storage directory to 'Librarys/Caches/ if it's not users related data.

Solution :
Replace 'NSDocumentDirectory' by 'NSCachesDirectory' while saving data.
