iOS 指压即达集成iOS9里的3D Touch的方法

1.前言　　

随着6S的到来，3DTouch被各大热门APP迅速普及，博主亲自体验后，发现使用便捷性大幅提高，随后自己照着文档，写了个Demo出来，分享给大家，希望能对有需要的朋友提供有一些帮助。

2.如何使用3D Touch？　　

2.1.主界面重按APP图标，弹出Touch菜单　　

在AppleDelegate文件中的程序入口处配置：

didFinishLaunchingWithOptions

//给App图标添加3D Touch菜单
//拍照
//菜单图标
UIApplicationShortcutIcon *iconCamera = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
//菜单文字
UIMutableApplicationShortcutItem *itemCamera = [[UIMutableApplicationShortcutItem alloc] initWithType:@"1" localizedTitle:@"拍照"];
//绑定信息到指定菜单
itemCamera.icon = iconCamera;
//相册
//菜单图标
UIApplicationShortcutIcon *iconPhotoLibrary = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeSearch];
//菜单文字
UIMutableApplicationShortcutItem *itemPhotoLibrary = [[UIMutableApplicationShortcutItem alloc] initWithType:@"2" localizedTitle:@"相册"];
//绑定信息到指定菜单
itemPhotoLibrary.icon = iconPhotoLibrary;
//绑定到App icon
application.shortcutItems = @[itemCamera,itemPhotoLibrary];

- (void)application:(UIApplication *)application performActionForShortcutItem:(nonnull UIApplicationShortcutItem *)shortcutItem completionHandler:(nonnull void (^)(BOOL))completionHandler; 

//照相type
if ([shortcutItem.type isEqualToString:@"1"]) {
 
 UIImagePickerController *picker = [[UIImagePickerController alloc] init];//初始化
 picker.allowsEditing = YES;//设置可编辑
 picker.sourceType = UIImagePickerControllerSourceTypeCamera;
 [self.window.rootViewController presentViewController:picker animated:YES completion:nil];//进入照相界面
 
}
//相册type
if ([shortcutItem.type isEqualToString:@"2"]) {
 UIImagePickerController *picker = [[UIImagePickerController alloc] init];//初始化
 picker.allowsEditing = YES;//设置可编辑
 picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
 [self.window.rootViewController presentViewController:picker animated:YES completion:nil];//进入图片库
