【代码笔记】iOS-对iphone手机进行判断的一些函数

代码：

#import "RootViewController.h"

//为判断手机的型号 -(NSString*)deviceString添加头文件
#import "sys/utsname.h"

@interface RootViewController ()

@end

@implementation RootViewController

{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
