可可触摸 - 获取设备信息

Question

我执行此任务来读取一些设备信息,如设备名称,类型,磁盘空间和iOS版本.我有一些方法可以知道这个设备是iPad,iPhone还是视网膜,但是我对进一步了解该设备毫无头绪.

Answer 1

阅读iOS版本:

NSString* iOSVersion = [[UIDevice currentDevice] systemVersion];

阅读iPad模型:

BOOL isIPad2 = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad &&
                            [UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]);
NSString*    iPadModel = [[UIDevice currentDevice] model];
            if (isIPad2)
                iPadModel = @"iPad2";

读取空闲/总空间磁盘:

- (NSNumber *) totalDiskSpace
{
    NSDictionary *fattributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:nil];
    return [fattributes objectForKey:NSFileSystemSize];
}

- (NSNumber *) freeDiskSpace
{
    NSDictionary *fattributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:nil];
    return [fattributes objectForKey:NSFileSystemFreeSize];
}
