[iOS]只配置一列数据时，onPickerConfirm/onPickerCancel/onPickerSelect第二个参数index返回空数组

如题

I got 1 column data，onPickerConfirm (pickedIndex == null)
won't happen in Android.

`getStyle

self.dataDry=[self.pickerDic objectForKey:@"pickerData"];

id firstobject=[self.dataDry firstObject];

// It help
_seleNum = 1;

if ([firstobject isKindOfClass:[NSArray class]]) {

`

modify in BzwPicker.m simply add a default value(it means 1) for _seleNum.

Did a few test, it works for me.
