带有各种警报正文的 UILocalNotification [英] UILocalNotification with various alert body

问题描述

如何使用各种警报正文重复 UILocalNotification?

How Can I repeat UILocalNotification with various alert body?

例如:

UILocalNotification *notif = [[UILocalNotification alloc] init]; 
notif.alertBody = @"Hello";
notif.repeatInterval = NSDayCalendarUnit;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];

通过使用此代码，通知将每天重复，我如何每天以不同的警报正文重复通知?

By using this code the notification will be repeated daily, how can I repeat the notification daily with different alert body each day?

谢谢.

推荐答案

您可以在 AppDelegate 中实现 application:didReceiveLocalNotification 方法，并增加一个day counter"变量.然后，为通知的警报正文安排一个新的 UILocalNotification 和一个字符串数组.使用日计数器获取更新的字符串.下面是一些示例代码:

You could implement the application:didReceiveLocalNotification method in the AppDelegate, and increase a 'day counter' variable. Then, schedule a new UILocalNotification with an array of strings for your notification's alert body. Use the day counter to get an updated string. Here's some example code:

在你的 AppDelegate.h 中:

In your AppDelegate.h:

@property (assign, nonatomic) int dayCount;

在您的 AppDelegate.m 中:

In your AppDelegate.m:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    [self scheduleLocalNotification];
    return YES;
}

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
    self.dayCount++;
    [self scheduleLocalNotification];
}

-(void)scheduleLocalNotification{
    NSArray *notifTextArray = [NSArray arrayWithObjects:@"Hello", @"Welcome", @"Hi there", nil];

    UILocalNotification *notif = [[UILocalNotification alloc] init];

    if(self.dayCount < notifTextArray.count){
        notif.alertBody = [notifTextArray objectAtIndex:self.dayCount];
    }
    else{
        self.dayCount = 0;
        notif.alertBody = [notifTextArray objectAtIndex:self.dayCount];
    }

    notif.fireDate = [NSDate dateWithTimeIntervalSinceNow:86400]; //86400 seconds in a day
    [[UIApplication sharedApplication] scheduleLocalNotification:notif];
}

只是一个选择，但希望它有所帮助.

Just an option, but hope it helps.
