Repeating self performSelector

I just wandered. If there is an easier way to repeat the codes below for 20 seconds. If so, how?

[self performSelector:@selector( move1) withObject:nil afterDelay:0.0]; [self performSelector:@selector( move2) withObject:nil afterDelay:0.2]; [self performSelector:@selector( move3) withObject:nil afterDelay:0.4]; [self performSelector:@selector( move1) withObject:nil afterDelay:0.8]; [self performSelector:@selector( move2) withObject:nil afterDelay:0.10]; [self performSelector:@selector( move3) withObject:nil afterDelay:0.12];

In my opinion, just try this code below,

Take one NSInteger in your .h file for example

 NSInteger intTmp;

then in the .m file call the NSTimer method, for example,

 [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(testMethod:) userInfo:nil repeats:YES];

And write a selector like this

 -(void)testMethod:(NSTimer *)pTmpTimer { intTmp += 1; if(intTmp <= 20) { [self performSelector:@selector( move1) withObject:nil afterDelay:0.0]; [self performSelector:@selector( move2) withObject:nil afterDelay:0.2]; [self performSelector:@selector( move3) withObject:nil afterDelay:0.4]; [self performSelector:@selector( move1) withObject:nil afterDelay:0.8]; [self performSelector:@selector( move2) withObject:nil afterDelay:0.10]; [self performSelector:@selector( move3) withObject:nil afterDelay:0.12]; } else { [pTmpTimer invalidate]; intTmp = 0; } }

From the above code, testMethod will ring 20 times, and according to your requirement, your code will repeat 20 times.

Hope this works for you.

Happy coding.

You can use NSTimer, and in the selector called by the timer, you can call the corresponding move method, which will be next.

you can use

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

userInfo can be used to transfer some data to a selector, from which a selector can be selected, which step goes next or which move has been called recently.

 NSTimer *myTimer = [NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(invokeMove:) userInfo:[NSNumber numberFromInt:1] repeat:NO];

Your selector may be:

 -(void)invokeMove:(id)nextMove { if ([nextMove isKindOfClass: [NSNumber class]]) { int veryNextMove = 0; switch ([nextMove intValue]) { case 1: veryNextMove = 1; case 2: veryNextMove = 2; case 3: veryNextMove = 3; } if (veryNextMove == 0) return; NSTimer *myTimer = [NSTimer scheduledTimerWithTimeInterval 0.2 target:self selector:@selector(invokeMove:) userInfo:[NSNumber numberFromInt:2] repeat:NO]; //Assuming you use ARC. } }

Schedule a timer at intervals of 1 and use the selector to write down your code.

 timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(callMethods) userInfo:nil repeats:YES];

selector method

  - (void) callMethods { static int i = 0; if(i < 19) { //your code here for(int j=0; j<2 ;j++) { [self performSelector:@selector( move1) withObject:nil afterDelay:(j*8)/10]; [self performSelector:@selector( move2) withObject:nil afterDelay:((j*8)/10)+0.2]; [self performSelector:@selector( move3) withObject:nil afterDelay:((j*8)/10)+0.4]; } } else { i = 0; [timer invalidate]; } i++; }
