iphone - Invalidate NSTimer not working -


I have a timer where I format the remaining time as a string: "mm: ss" and When the string value of time is 00:00, I want to invalidate the timer. For some reason this does not work, even when I log in the remaining time, I think that is the correct form of value, so I do not know why there is no branch in "counttime".

Can anyone help? 

  - (id) init {if (self = [super init]) {NSDate * date = [[NSDate alloc] init]; Self.intervalLength = Date; [Date release]; NSString * timeRem = [[NSString alloc] init]; Self. Timeline = timeline; [Time release]; Formatter = [[NSDateFormatter alloc] init]; [Formatter setDateFormat: @ "mm: ss"]; Notification = [NSOtification NotificationWith: @ "Timer" item: Self]; NotificationandRed = [NSOtification NotificationName: @ "TimerFinished" Object: Self]; NSMutableDictionary * information = [[NSMUTABADADA] alloc] init]; [Information set object: formatter forKey: @ "format"]; [Info setObject: Notice for: @ "Notification"]; [Information set object: Key for notification: @ "Notification End"]; NSTimer * timer = [[NSTimer alloc] init]; Timer = [[Enestimer Elok] Init]; Timer = [nstimer timer with time interval: 1.0 target: auto selector: @sillector (counttime) userinfo: information repeats: yes]; Self.intervalTimer = Timer; } Healthy return; } - (Zero) StartInternval Countdown {runLoop = [NSRunLoop currentRunLoop]; [Run Loop Adapter: self.intervalTimer forMode: NSDefaultRunLoopMode]; } - (zero) countTime: (NSTimer *) timer {if (self.timeRemaining == @ "00:00") {[invalid timer]; Timer = zero; [[NSNotificationCenter defaultCenter] Post Notification: [[Timer User Efo] ObjectForekey: @ "Notification End"]]; } D = [Automator wall timetable time-interval: -1.0]; Self.intervalLength = [D copy]; Self.timeRemaining = [[[Timer user information] ObjectForreake: @ "format"] stringFromDate: d]; [[NSNotificationCenter defaultCenter] Postnotation: [[Timer user ifo] ObjectForcae: @ "Notification"]];

You're comparing the parallelism rather than string similarity. You want 

  [self.time.RemainingEqualToString: @ "00:00"]

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
