3D Touch

去年6s上市之后推出了3DTouch功能,现在很多app都运用了次功能,我对这个功能一直很感兴趣,可是之前一直没钱买(穷啊),现在攒钱买了部8手6s后马上去感受了一下3DTouch,如图.

可以看见现在主流app都拥有这个功能,这个功能确实是简洁一些.
那么看看代码吧.
在AppDelegate里面

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //3D Touch 分为重压和轻压手势, 分别称作POP(第一段重压)和PEEK(第二段重压), 外面的图标只需要POP即可.
    //POP手势图标初始化
    //使用系统自带图标
    UIApplicationShortcutIcon *icon1 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
    UIApplicationShortcutIcon *icon2 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
    //使用自己的图片
//    UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithTemplateImageName:@"自己的图片"];
    UIApplicationShortcutItem *item1 = [[UIApplicationShortcutItem alloc]initWithType:@"item1" localizedTitle:@"标题1" localizedSubtitle:nil icon:icon1 userInfo:nil];
    UIApplicationShortcutItem *item2 = [[UIApplicationShortcutItem alloc]initWithType:@"item2" localizedTitle:@"标题2" localizedSubtitle:nil icon:icon2 userInfo:nil];
    NSArray *array = @[item1,item2];
    [UIApplication sharedApplication].shortcutItems = array;
    return YES;
}

这就是创建按压图标后出来的小菜单,大家看看效果.

点击菜单后可以实现你写的跳转方法.代码如下:

#pragma mark - 3DTouch触发的方法
-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
{
    //这里可以实现界面跳转等方法
    if ([shortcutItem.type isEqualToString:@"item1"]) {
        SFSafariViewController *sv = [[SFSafariViewController alloc]initWithURL:[NSURL URLWithString:@"http://weibo.com/p/1005055844400745/home?from=page_100505_profile&wvr=6&mod=data&is_all=1#place"]];
        _window.rootViewController = sv;
        NSLog(@"按压了第一个标题");
    }
    else if ([shortcutItem.type isEqualToString:@"item2"])
    {
        ViewController *vc = [[ViewController alloc]init];
        _window.rootViewController = vc;
        NSLog(@"按压了第二个标题");
    }
}

点击第一个标题进入safari浏览器打开的网页,点击第二个进入ViewController.效果图如下:

在Viewcontroller里面我放了一个label,使其也能实现3DTouch效果,看看代码.
Viewcontroller.m

#import "ViewController.h"
#import <SafariServices/SafariServices.h>
#define URL @"http://weibo.com/p/1005055844400745/home?from=page_100505_profile&wvr=6&mod=data&is_all=1#place"
@interface ViewController ()<UIViewControllerPreviewingDelegate>
@property(nonatomic, strong)UILabel *weiboLabel;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor whiteColor];
}

-(void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit
{
    //固定这么写
    [self showViewController:viewControllerToCommit sender:self];
}

-(UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
    //location就是重压点坐标,如果按压点在label上执行以下方法
    if (location.x > 100 && location.x < 200 && location.y > 100 && location.y < 200) {
        SFSafariViewController *mySV = [[SFSafariViewController alloc]initWithURL:[NSURL URLWithString:URL]];
        //第一次按压时,弹出的窗口尺寸,再次按压则跳转到mySV
        mySV.preferredContentSize = CGSizeMake(0, 400);
          previewingContext.sourceRect = _weiboLabel.frame;//设置高亮区域
        return mySV;
    }
    return nil;
}

-(void)loadView
{
    [super loadView];
    _weiboLabel = [[UILabel alloc]initWithFrame:CGRectMake(100, 100, 100, 100)];
    _weiboLabel.text = @"我的微博";
    [self.view addSubview:_weiboLabel];
    //注册代理
    [self registerForPreviewingWithDelegate:self sourceView:self.view];
}

大家看看效果图:

这里第一次按压先弹出窗口,如果松手则关闭窗口,如果再次按压才会跳转到浏览器界面.
代码还有不完善的地方,大家可以改改.
好了,今天就到这里,祝大家开心😄
