@interface ViewController ()

@implementation ViewController

- (void)viewDidLoad {

    CGPoint current = [touch locationInView:self.view];

    CGPoint previous = [touch previousLocationInView:self.view];

    CGFloat offX = current.x - previous.x;

        if (_mainView.frame.origin.x>0) {

            _leftView.hidden = NO;

            CGRect frame = _mainView.frame;

            frame.origin.x +=offX;

            frame.origin.y +=offX*0.2;

            frame.size.height -=offX*0.4;

            _mainView.frame = frame;

        }else if(_mainView.frame.origin.x<=0){

            _leftView.hidden = YES;

            CGRect frame = _mainView.frame;

            frame.origin.x +=offX;

            frame.origin.y +=(-offX)*0.2;

            frame.size.height -=(-offX)*0.4;

            _mainView.frame = frame;

        }

}

@end

该程序运行是会有Bug的，，求高人指点一二，算法上没有问题，个人感觉比

    左右滑动都正常   多次左右滑动后
