Question

我正在寻找答案,我没有任何工作。

我有一位国家安全日记官,作为上诉人的属性,这个国家安全日记官应随时开枪,即使其行动是在背景(它是一个地方化标志,因此可以永远运作)的情况下。

This is the code:

if(conectar){
            self.myTimer = [[NSTimer scheduledTimerWithTimeInterval:10.0
                                                            target:self
                                                          selector:@selector(abrirPresencia)
                                                          userInfo:nil
                                                           repeats:NO]retain];
        iii
        else{
            self.myTimer = [[NSTimer scheduledTimerWithTimeInterval:10.0
                                                    target:self
                                                  selector:@selector(cerrarPresencia)
                                                  userInfo:nil
                                                           repeats:NO]retain];
        iii

After 10 seconds the app crashes, I have breakpoints in both methods and it doesnt stop, as if the method wasnt even called, instead of firing the method it crashes.

Here are the methods:

-(void)cerrarPresencia{
NSLog(@"SOY EL TIMERRRRR!!!! %@");
//[[UIApplication sharedApplication] applicationState] == UIApplicationStateBackground
if (YES){
    [self.location stopUpdatingLocation];
    [self disconnect];

iii
else{
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ups!"
                                                        message:@"Según tu perfil querrías estar desconectado pero como lo estás usando hemos incluido este horario. Para cambiarlo sólo tienes que ir a editar perfil."
                                                       delegate:self 
                                              cancelButtonTitle:@"Ok" 
                                              otherButtonTitles:nil];
    [alertView show];

    [alertView release];

-(void)abrirPresencia{
NSLog(@"SOY EL TIMERRRRR!!!! %@");
if (YES){
    [self.location stopUpdatingLocation];
    [self disconnect];

iii
else{
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ups!"
                                                        message:@"Según tu perfil querrías estar desconectado pero como lo estás usando hemos incluido este horario. Para cambiarlo sólo tienes que ir a editar perfil."
                                                       delegate:self 
                                              cancelButtonTitle:@"Ok" 
                                              otherButtonTitles:nil];
    [alertView show];

    [alertView release];

财产是:

@property (nonatomic, retain)NSTimer *myTimer;

任何想法?

Answer 1

NSLog(@"SOY EL TIMERRRRR!!!! %@");

提醒各位注意这一行文。

注意这些警告。页: 1 如果你不通过这些进一步的论点,其职能仍然处于它期望提出的论点的位置,可以发现,并造成坠毁。

Answer 2

选择人错了,其形式必须是:

-(ave) abrir Presencia:NStimer*>thetimer

Also the selector needs to specify an argument with a trailing colon: selector:@selector(abrirPresencia)

摘自Amp/59/ docs:

+ (NSTimer *)scheduledTimerWithTimeInterval:(NSTimeInterval)seconds target:(id)target selector:(SEL)aSelector userInfo:(id)userInfo repeats:(BOOL)repeats

发出信号,在时间大火时瞄准目标。选择人必须签名如下:

- (void)timerFireMethod:(NSTimer*)theTimer
