iOS App 快捷选项 shortcutItems

• 通过3D Touch按压App图标，会显示快捷选项，点击选项可快速进入到App的特定页面，提升了App的体验。
• 这是通过 UIApplicationShortcutItem 实现的，直接上代码。

#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    [self creatShortcutItem];
    
    if(launchOptions){
        if([[[UIDevice currentDevice] systemVersion] doubleValue]>=9.0){
            UIApplicationShortcutItem *shortcutItem = [launchOptions valueForKey:UIApplicationLaunchOptionsShortcutItemKey];
            //如果是从快捷选项标签启动app，则根据不同标识执行不同操作，然后返回NO，防止调用- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
            if (shortcutItem) {
                NSLog(@"----- %@ ------ = %s",shortcutItem.type,__FUNCTION__);
                //判断先前我们设置的快捷选项标签唯一标识，根据不同标识执行不同操作
                [self dealWithShortcut:shortcutItem.type];
                return NO;
            }
        }
    }
    
    return YES;
}

#pragma mark - 创建 shortcutItem

    //创建系统风格的icon
    //    UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];

    [UIApplication sharedApplication].shortcutItems = @[payItem,scanItem,qrcodeItem,redpackItem];
}

- (void)dealWithShortcut:(NSString*)type {
    NSLog(@"dealWithShortcut = %@",type);
    
    if([type isEqualToString:@"com.codingchou.test.pay"]){
        NSLog(@"快捷方式 -- 支付");
        
    } else if([type isEqualToString:@"com.codingchou.test.scan"]){
        NSLog(@"快捷方式 -- 扫一扫");
        
    } else if([type isEqualToString:@"com.codingchou.test.qrcode"]){
        NSLog(@"快捷方式 -- 付款");
        
    } else if([type isEqualToString:@"com.codingchou.test.redpacket"]){
        NSLog(@"快捷方式 -- 红包");
        
    }
}

#pragma mark - 当app已启动, 点击shortcutItem回调
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler {
    NSLog(@"快捷方式 : %@",shortcutItem.type);
    
    [self dealWithShortcut:shortcutItem.type];
    
    completionHandler(YES);
}
