【代码笔记】iOS-判断是否是iPhone5

一，代码。

#import "RootViewController.h"

// 判断是否是iPhone5
#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)]\
? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size)\
|| CGSizeEqualToSize(CGSizeMake(1136, 640), [[UIScreen mainScreen] currentMode].size) : NO)

@interface RootViewController ()

@end

@implementation RootViewController

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

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

    self.title=@"isIphone5";

    //判断是否为iPhone5
    NSLog(@"---isIphone5---%i",iPhone5);

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

二，输出。
