Question

通常，我在Appdelegate.m中设置UIUserNotificationSettings

但是现在我想在UIViewcontroller中使用它，比如在UIViewcontroller中有一个UIButton，当我点击它时，它会调用这个函数，有什么想法吗？

Answer 1

试试这个：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
     NSLog(@"Receive remote notification : %@",userInfo);

     YourViewController *login=[storyboard instantiateViewControllerWithIdentifier:@"YourViewContollerIDName"];
     MainNavigationViewController *mainNavigation=[storyboard instantiateViewControllerWithIdentifier:@"MainNavigationViewController"];
     [mainNavigation setViewControllers:@[login] animated:NO];
     self.window.rootViewController=mainNavigation;
}

或

Appdelegate.m

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { NSLog(@"Receive remote notification : %@",userInfo); [[NSNotificationCenter defaultCenter]postNotificationName:@"Notification" object:self userInfo:userInfo]; }

YourViewContoller.m

-(void)viewWillAppear:(BOOL)animated{ [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(receiveNotification:) name:@"Notification" object:nil]; } - (void)receiveNotification:(NSNotification *) notification{ if ([[notification name] isEqualToString:@"Notification"]) { //call your function } [[NSNotificationCenter defaultCenter] removeObserver:self]; }

基本上与按下按钮的反应基本相同，只需使用UIApplication.shared而不是使用application提供的AppDelegate，例如，（Swift语法）：

UIApplication.shared.registerForRemoteNotifications()

此外，我建议您实施自己的自定义UserNotificationManager：

class UserNotificationManager: NSObject, UNUserNotificationCenterDelegate { ... }

我希望以下代码可以帮助您，

创建一个名为UIUserNotifications的新类，并将以下代码添加到.h文件

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface UIUserNotificationsHandler : NSObject
+ (void)registerUserNotifications;
@end

并将代码发送到.m文件。然后从ViewController类中调用该函数

#import "UIUserNotificationsHandler.h"

@implementation UIUserNotificationsHandler
+ (void)registerUserNotifications{
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert
                                            | UIUserNotificationTypeBadge
                                            | UIUserNotificationTypeSound
                                            categories:nil];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
@end

如何在任何uiviewcontroller中打开UIUserNotificationSettings
