UIPickerView設置選擇

Question

我有一個uipickerview，您可以選擇已設置到數組中的項目，但我正在努力解決如何將uilabel的文本設置爲選定選項。

這裏是我用來創建uipicker委託和數據源代碼：

-(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

在此先感謝

在下面的方法

集文本標籤

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { 
     yourLbl.text = [[treatments objectAtIndex:row]valueForKey:@"treatmentName"]; 
}
