Answer 2

我们可以隐藏其组件选择的pickerview，如下所示......

- （void）pickerView：（UIPickerView *）pickerView didSelectRow：（NSInteger）row inComponent：（NSInteger）component {

countryCodeString = [NSString stringWithFormat：@＆＃34; +％@＆＃34;，[array_countryCode objectAtIndex：row]];

[countryCodeButton setTitle：countryCodeString forState：UIControlStateNormal];

[picker removeFromSupperView]; }
