- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {
    labelX.text = [NSString stringWithFormat:@"%@%f", @"X: ", acceleration.x];
    labelY.text = [NSString stringWithFormat:@"%@%f", @"Y: ", acceleration.y];
    labelZ.text = [NSString stringWithFormat:@"%@%f"开发者_如何学C, @"Z: ", acceleration.z];


You have two options: store one value each in three, corresponding arrays, or create an object to store those three values and create an object at each invocation of your delegate method.

In either case, I'd create an NSMutableArray instance variable to store these in. The second option would be preferable if you're going to be working with these in the future, since you can add more information to the objects, such as timestamps or something.
