我有个问题; 在我的程序中，如果我调用 2 次
[self performSelectorOnMainThread:@selector(callDectectionMove:) withObject:[NSNumber numberWithInt:(int)i] waitUntilDone:false];
我是否创建了 2 个线程？因为在我的程序中我不确定创建 2 个线程。
谢谢
-(void)callDectectionMove:(NSNumber*)arrayIndex{
NSMutableDictionary *myDictionary = [[NSMutableDictionary alloc] init];
[myDictionary setObject:arrayIndex forKey:@"arrayIndex"];
identificationMove *identifier = [[identificationMove alloc]init];
[identifier setArrayIndex:(NSNumber*)arrayIndex];
[identifier detectionMove];
[identifier release];
}
-(void)detectPositionMovement{
for(int i = 0; i< [self.arrayMovement count]; i++){
if((actualAccelerometerX+sensibilityMovement) > [[[[self.arrayMovement objectAtIndex:i] arrayPositionMove]objectAtIndex:0] valueX] && (actualAccelerometerX-sensibilityMovement) < [[[[self.arrayMovement objectAtIndex:i] arrayPositionMove]objectAtIndex:0] valueX] &&
(actualAccelerometerY+sensibilityMovement) > [[[[self.arrayMovement objectAtIndex:i] arrayPositionMove]objectAtIndex:0] valueY] && (actualAccelerometerY-sensibilityMovement) < [[[[self.arrayMovement objectAtIndex:i] arrayPositionMove]objectAtIndex:0] valueY] &&
(actualAccelerometerZ+sensibilityMovement) > [[[[self.arrayMovement objectAtIndex:i] arrayPositionMove]objectAtIndex:0] valueZ] && (actualAccelerometerZ-sensibilityMovement) < [[[[self.arrayMovement objectAtIndex:i] arrayPositionMove]objectAtIndex:0] valueZ])
[self performSelectorOnMainThread:@selector(callDectectionMove:) withObject:[NSNumber numberWithInt:(int)i] waitUntilDone:false];
}
}
