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...
The UILabel (I will assume you use it) takes a NString to be displayed. You need to add the numbers first and then make the string that can be added to the label.
ReplyDeletemyLabel.text = [NSString stringWithFormat:@"%d", originalValue + diff];
I'm not sure what exactly you want but here's my guess:
ReplyDeleteYou have a variable that keeps a score on an UILabel object, and you need to add or subtract this value depending on some type of action.
This is how I would do it:
@interface Scoreboard : NSObject {
IBOutlet UILabel *label;
int counter;
}
- (IBAction)addToCounter;
- (IBAction)subtractToCounter;
- (void)updateLabel;
@end
@implementation Scoreboard
- (IBAction)addToCounter {
counter++;
[self updateLabel];
}
- (IBAction)subtractToCounter {
counter--;
[self updateLabel];
}
- (void)updateLabel {
label.text = [NSString stringWithFormat:@"Score = %i", counter];
}
@end
I just wrote this from memory but I don't think there is any errors. I hope that helps you. Good luck!
