去年6s上市之后推出了3DTouch功能,現在很多app都運用了次功能,我對這個功能一直很感興趣,可是之前一直沒錢買(窮啊),現在攢錢買了部8手6s后馬上去感受了一下3DTouch,如圖.
3Dtouch
可以看見現在主流app都擁有這個功能,這個功能確實是簡潔一些.
那么看看代碼吧.
在AppDelegate里面
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//3D Touch 分為重壓和輕壓手勢, 分別稱作POP(第一段重壓)和PEEK(第二段重壓), 外面的圖標只需要POP即可.
//POP手勢圖標初始化
//使用系統自帶圖標
UIApplicationShortcutIcon *icon1 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
UIApplicationShortcutIcon *icon2 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
//使用自己的圖片
// UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithTemplateImageName:@"自己的圖片"];
UIApplicationShortcutItem *item1 = [[UIApplicationShortcutItem alloc]initWithType:@"item1" localizedTitle:@"標題1" localizedSubtitle:nil icon:icon1 userInfo:nil];
UIApplicationShortcutItem *item2 = [[UIApplicationShortcutItem alloc]initWithType:@"item2" localizedTitle:@"標題2" localizedSubtitle:nil icon:icon2 userInfo:nil];
NSArray *array = @[item1,item2];
[UIApplication sharedApplication].shortcutItems = array;
return YES;
}
這就是創建按壓圖標后出來的小菜單,大家看看效果.
點擊菜單后可以實現你寫的跳轉方法.代碼如下:
#pragma mark - 3DTouch觸發的方法
-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
{
//這里可以實現界面跳轉等方法
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(@"按壓了第一個標題");
}
else if ([shortcutItem.type isEqualToString:@"item2"])
{
ViewController *vc = [[ViewController alloc]init];
_window.rootViewController = vc;
NSLog(@"按壓了第二個標題");
}
}
點擊第一個標題進入safari瀏覽器打開的網頁,點擊第二個進入ViewController.效果圖如下:
在Viewcontroller里面我放了一個label,使其也能實現3DTouch效果,看看代碼.
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
{
//固定這么寫
[self showViewController:viewControllerToCommit sender:self];
}
-(UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
//location就是重壓點坐標,如果按壓點在label上執行以下方法
if (location.x > 100 && location.x < 200 && location.y > 100 && location.y < 200) {
SFSafariViewController *mySV = [[SFSafariViewController alloc]initWithURL:[NSURL URLWithString:URL]];
//第一次按壓時,彈出的窗口尺寸,再次按壓則跳轉到mySV
mySV.preferredContentSize = CGSizeMake(0, 400);
previewingContext.sourceRect = _weiboLabel.frame;//設置高亮區域
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];
//注冊代理
[self registerForPreviewingWithDelegate:self sourceView:self.view];
}
大家看看效果圖:
這里第一次按壓先彈出窗口,如果松手則關閉窗口,如果再次按壓才會跳轉到瀏覽器界面.
代碼還有不完善的地方,大家可以改改.
好了,今天就到這里,祝大家開心??
