This repositories contains two parts.

CHPickerView is ios7 style picker on ios5.
CHPickerElement is infint scrollview.

Both of them can support horizontal and vertical.

It's easy to use.

CHPickerElement *vv = [[CHPickerElement alloc] initWithFrame:CGRectMake(250, 50, 30, 130)];
vv.backgroundColor = [UIColor greenColor];
vv.sourceArray = @[@"0",@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12",@"13",@"14",@"15"];
[self.view addSubview:vv];

or

CHPickerView *vv = [[CHPickerView alloc] initWithFrame:CGRectMake(10, 40, 150, 80)];
    vv.direction = CHPickerHorizontalDirection;
    vv.pickerLabelTextAlignment = NSTextAlignmentCenter;
    vv.maskBackgroundColor = [UIColor greenColor];
    vv.pickerBackgroundColor = [UIColor grayColor];
    vv.maskLabelFont = [UIFont systemFontOfSize:30];
    vv.maskLabelTextAlignment = NSTextAlignmentCenter;
    vv.maskAtIndex = 2;
    vv.pickerStartIndex = -2;
    vv.delegate = self;
    vv.currentPointOffset = CGPointMake(vv.contentHeight*2,0);
    vv.sourceArray = @[@"0",@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12",@"13",@"14",@"15"];
