Hi! I have been posted content of ccna1 final exam (latest and only question.) I will post the answer and insert image on sunday. If you care, please subscribe your email an become a first person have full test content. Subcribe now Some question have not content because this question have images content. So that can you wait for me? SUNDAY 1. A user sees the command prompt: Router(config-if)# . What task can be performed at this mode? Reload the device. Perform basic tests. Configure individual interfaces. Configure individual terminal lines. 2. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A leaving ATL leaving...
You can use method in your app delegate:
ReplyDelete- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
to check how many times it was launched. Then you can simply use standard user defaults to read/write the value:
NSInteger i = [[NSUserDefaults standardUserDefaults] integerForKey:@"numOfLCalls"];
[[NSUserDefaults standardUserDefaults] setInteger:i+1 forKey:@"numOfLCalls"];
After that check if "i" is greater then 5 and send a message to view controller so it will put alert message after its view loads or simply call the user defaults again where you want to display the alert and check value.
use NSUserDefaults in applicationDidBecomeActive:.
ReplyDeleteNSUserDefaults * userDefaults = [NSUserDefaults standardUserDefaults];
NSInteger appLaunchAmounts = [userDefaults integerForKey:@"LaunchAmounts"];
if (appLaunchAmounts == 5)
{
//Use AlertView
}
[userDefaults setInteger:appLaunchAmounts+1 forKey:@"LaunchAmounts"];
You could count the number of launches using NSUserDefaults.

You would implement your functionality in application delegate. Most probably in - (void)applicationDidBecomeActive:(UIApplication *)application method.
First you check if your launchesSoFar value is store. If not (if you get nil) you initialize it to 1 and don't forget to synchronize. If it exists already you increment it and again - sznchronize. If it's >=5 then do what you wan't to do.
