Using these three methods, intercepted "three fingers simultaneously knocked two down" operation. Then deal with their own under

NSUInteger numTaps = [[touches anyObject] tapCount] ;/ / point
fewNSString * tapsMessage = [[NSString alloc]
initWithFormat: @ "% d taps detected", numTaps];
tapsLabel.text = tapsMessage;
[TapsMessage release];

NSUInteger numTouches = [touches count] ;/ / number of touch points
NSString * touchMsg = [[NSString alloc] initWithFormat:
@ "% D touches detected", numTouches];
touchesLabel.text = touchMsg;
[TouchMsg release];

View your finger on the monitor, such as a few fingers, a few points, can be obtained.

No, right?
Or will achieve UIScrollViewDelegate on UIScrollView zoom bar.

NSUInteger numTaps = [[touches anyObject] tapCount] ;/ / point
fewNSUInteger numTouches = [touches count] ;/ / number of touch points

Where these two write it, I write these two touchesBegan to determine if there then, if it is scaled on the return, seemingly to no avail it

Looks like NSUInteger numTouches = [touches count] ;/ / always get a few touch points what circumstances it

Not do it, looked at the set of API developer.app.com which said only capture a single finger touch screen three fingers will not do so to capture the shot a few times in a row, but do not catch a few fingers shot ...... < br />
