行爲pickerview titleForRow總是從2開始

Question

我在我的應用程序中使用UIpickerview。問題是我的pickerview titleforrow函數總是返回3行，儘管numberofRowsinComponent返回更多行。

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent: 
    (NSInteger)component { 

return [filteredTerms count]; } 


- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow: 
    (NSInteger)row forComponent:(NSInteger)component { 


CreateOrder *order = [filteredTerms objectAtIndex:row]; 

NSString *title; 
title = order.kBranchName; 

return title; } 

我甚至試圖硬編碼返回的數字或行，但它不工作。該titleforrow行始終從2

Answer 1

試試這個

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component 
{ 

return [filteredTerms objectAtIndex:row]; 

}
