UIPickerView设置选择

Question

我有一个uipickerview，您可以选择已设置到数组中的项目，但我正在努力解决如何将uilabel的文本设置为选定选项。

这里是我用来创建uipicker委托和数据源代码：

-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { 
    return [treatments count]; 
} 

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { 
    return 1; 
} 

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component 
{ 
     return[[treatments objectAtIndex:row]valueForKey:@"treatmentName"]; 
} 

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

} 

我所知道的是，它在uipicker didselectrow功能做

在此先感谢
