【问题描述】：
我对 iOS 应用程序开发非常陌生，我一直在学习教程来建立我的职业生涯。因此，从我开始尝试根据客户项目在 Objective C 中实现静态快速操作。我能够在按下图标时添加键并获得选项。但是当我按下快速操作时，什么也没有发生，它只是启动应用程序。我研究了很多，我尝试过，但徒劳无功。下面是我写的 Appdelegate 代码：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
BOOL shouldPerformAdditionalDelegateHandling = YES;
// Check API availiability
// UIApplicationShortcutItem is available in iOS 9 or later.
if([[UIApplicationShortcutItem class] respondsToSelector:@selector(new)]){
NSLog(@"HERE");
// [self configDynamicShortcutItems];
// If a shortcut was launched, display its information and take the appropriate action
UIApplicationShortcutItem *shortcutItem = [launchOptions objectForKeyedSubscript:UIApplicationLaunchOptionsShortcutItemKey];
if(shortcutItem)
{
NSLog(@"shortcut launch");
// When the app launch at first time, this block can not called.
[self handleShortCutItem:shortcutItem];
// This will block "performActionForShortcutItem:completionHandler" from being called.
shouldPerformAdditionalDelegateHandling = NO;
}else{
NSLog(@"normal launch");
// normal app launch process without quick action
// [self launchWithoutQuickAction];
}
}else{
// Less than iOS9 or later
// [self launchWithoutQuickAction];
}
return shouldPerformAdditionalDelegateHandling;
}
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler{
NSLog(@"performActionForShortcutItem");
BOOL handledShortCutItem = [self handleShortCutItem:shortcutItem];
completionHandler(handledShortCutItem);
}
/**
* @brief handle shortcut item depend on its type
*
* @param shortcutItem shortcutItem selected shortcut item with quick action.
*
* @return return BOOL description
*/
- (BOOL)handleShortCutItem : (UIApplicationShortcutItem *)shortcutItem{
BOOL handled = NO;
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
if ([shortcutItem.type isEqualToString:@"PlayMusic"]) {
handled = YES;
NSLog(@"Play");
secondview *vc = [storyboard instantiateViewControllerWithIdentifier:@"second"];
self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
}
else if ([shortcutItem.type isEqualToString:@"StopMusic"]) {
handled = YES;
NSLog(@"Stop");
// ThirdViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"thirdVC"];
//
// self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
}
return handled;
}
但是，当我深按主页图标但单击时没有任何操作发生时，我可以看到快速操作项目。我检查了 info.plist 中的密钥和它的相同。 Quick Actions
下面是添加静态动作的 info.plist
<key>UIApplicationShortcutItems</key>
<array>
<dict>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypePlay</string>
<key>UIApplicationShortcutItemTitle</key>
<string>Play</string>
<key>UIApplicationShortcutItemSubtitle</key>
<string>Start playback</string>
<key>UIApplicationShortcutItemType</key>
<string>PlayMusic</string>
</dict>
<dict>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypePlay</string>
<key>UIApplicationShortcutItemTitle</key>
<string>STOP</string>
<key>UIApplicationShortcutItemSubtitle</key>
<string>Stop playback</string>
<key>UIApplicationShortcutItemType</key>
<string>StopMusic</string>
</dict>
有人可以帮我解决我做错的地方吗？
