Question

插入圖像前uipickerview

插入圖片後在uipickerview

- (UIView *) pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row 
      forComponent:(NSInteger)component reusingView:(UIView *)view { 
    CGRect imageFrame = CGRectMake(0.0, 0.5, 255, 250); 
    UIImageView *label = [[UIImageView alloc] 
          initWithFrame:imageFrame]; 
label.backgroundColor=[UIColor scrollViewTexturedBackgroundColor]; 
    [label sendSubviewToBack:pview]; 

[pview sendSubviewToBack: label]; 
    [pview addSubview:label]; 


return label; 

} 

Answer 1

在你的代碼寫了這個： -

[label sendSubviewToBack:pview]; 

[pview sendSubviewToBack: label]; 

我認爲你是在這裏做什麼錯誤..

你只需要使用這樣的： -

[label sendSubviewToBack:pview]; 
[label addSubview:pview]; 

刪除此

[pview sendSubviewToBack: label]; 

，將工作fine..if不會隨意問..享受..
