//如果值不为空，则`pickerView`会把当前值选中，
demo中是把上一个值记录为`selectedTitleOrCustomModels`，
当模式为`MXPickerViewModeCustom`, `selectedTitleOrCustomModels` 应该为`customModels`, 是一个 `NSArray`数组类型, 如 `@[@"0-1", @"1-2", @"2-3"]`
当模式为日期一类的，如`MXPickerViewModeDD`..., `selectedTitleOrCustomModels`应该为`selectedTitle`, 是一个用空格拼接的`NSString`数组类型, 格式类似于`2018 12 12`
当模式为`UIDatePicker`一类的, 如`MXPickerViewModeDateAndTime`, `selectedTitleOrCustomModels` 不应该传, 默认值总是nil!
