本地通知消失在手機的狀態欄。如何讓它留在那裏，直到有人訪問它

Question

我有以下代碼，它創建一個本地通知，出現在手機的狀態欄中。創建的通知消失後即使我沒有訪問它，也是一小會兒。

UILocalNotification *localNotification = [[[UILocalNotification alloc] init] autorelease]; 

if (!localNotification) 
    return; 

// Current date 
NSDate *date = [NSDate date]; 

// Add one minute to the current time 
NSDate *dateToFire = [date dateByAddingTimeInterval:60]; 

// Set the fire date/time 
[localNotification setFireDate:dateToFire]; 
[localNotification setTimeZone:[NSTimeZone defaultTimeZone]]; 
localNotification.repeatInterval = 0; 

// Create a payload to go along with the notification 
NSArray *array = [NSArray arrayWithObjects:@"Value 1", @"Value 2", nil]; 
NSDictionary *data = [NSDictionary dictionaryWithObject:array forKey:@"payload"]; 
[localNotification setUserInfo:data]; 


// Setup alert notification 
[localNotification setAlertBody:@"Incoming notification"]; 
[localNotification setAlertAction:@"Open App"]; 
[localNotification setHasAction:YES];  

// Schedule the notification   
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; 

有人可以幫助我創建一個通知，留在狀態欄，直到用戶訪問它嗎？ 謝謝

沒有辦法做到這一點，iOS SDK不提供任何方式讓通知留在狀態欄中，直到用戶解僱它爲止。
