iOS 使用OC语言开发3DTouch功能

    3DTouch功能是iphone的专属功能,我们在开发中用到的几率很大,本篇文章讲解的是应用图标按压的3DTouch功能和界面某个控件按压的3DTouch功能,我的邮箱是KenenCS@163.com,欢迎多多交流!

一.应用图标的3DTouch功能开发

先来一张效果图:

看一下具体代码:

AppDelegate.h

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    //设置APP图标的3DTouch
    [self set3DTouch];
    
    return YES;
}
 
#pragma mark-------设置APP图标的3DTouch</span>
- (void)set3DTouch {
    
    //使用系统自带图标(Type代表图标类型)
    UIApplicationShortcutIcon *icon1 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeHome];
    UIApplicationShortcutIcon *icon2 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeLove];
    
    //也可以使用自己制作的图片
    //UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithTemplateImageName:@"自己的图片"];
    
    //添加标题和图片(这里示范两个标题)
    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];
    
    //添加到数组
    NSArray *array = @[item1,item2];
    //这个就是关键代码
    [UIApplication sharedApplication].shortcutItems = array;
    
}
 
#pragma mark-----APP图标的3DTouch代理方法
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler {
    
    //3DTouch实现界面跳转
    if ([shortcutItem.type isEqualToString:@"item1"]) {
        //跳转界面记得设置rootViewController</span>
        NSLog(@"按压了第一个标题");
    }else if ([shortcutItem.type isEqualToString:@"item2"]) {
        //跳转界面记得设置rootViewController
        NSLog(@"按压了第二个标题");
    }
    
}

二.界面按压3DTouch功能

再来看一张效果图:

看一下具体代码:

首先导入SafariServices.framework这个框架,看这个名字你应该就知道是和Safari浏览器有关的,没错,你想的很对!

ViewController.m

#import <SafariServices/SafariServices.h>
 
@interface ViewController ()<UIViewControllerPreviewingDelegate> {
    UILabel *label;
}
 
@end
 
@implementation ViewController
 
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    self.view.backgroundColor = [UIColor whiteColor];
    
}
  
-(void)loadView {
    [super loadView];
    
    //创建个label,一会儿就按压它
    label = [[UILabel alloc]initWithFrame:CGRectMake(100, 100, 100, 100)];
    label.text = @"我的微博";
    label.textAlignment = NSTextAlignmentCenter;
    [self.view addSubview:label];
    //注册代理
    [self registerForPreviewingWithDelegate:self sourceView:self.view];
    
}
 
#pragma mark----PreviewingDelegate
-(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:@"http://www.baidu.com"]];
        //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);
        //设置高亮区域
        previewingContext.sourceRect = label.frame;
    
        return mySV;
    
}
 
    return nil;
}
 
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
 
@end
