效果图如下，

详细用法就不说了，网上比比皆是，记一下心得吧

默认没有深蓝色的选择指示条，要设置 pickView.showsSelectionIndicator = YES ;才会有
选择指示条的高度无法设置，只能通过想pickView中添加一个背景透明的图片蒙版来模拟这个东西
默认选择某一项 [pickView.selectRow:1 inComponent:0 animated:YES] ; //第一栏第二行
设置每一项显示的文本，重载相关协议的- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component方法
设置每一项显示的文本，并且设置字体，只能加subView了

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row

forComponent:(NSInteger)component reusingView:(UIView *)view

{

UILabel * myView = view ? (UILabel *) view : [[UILabel alloc] initWithFrame:CGRectMake(0.0f,0.0f, 90.0f, 30.0f)];

myView.text = @"hello guys" ;

[myView setFont:[UIFont systemFontOfSize:16 ]];

myView.backgroundColor = [UIColor clearColor];

return myView;

}
