滾動我有我我通過一個數組發展UIPicker。在我的陣列我目前節省10個它的價值觀和UIPicker計算陣列中的行數，然後選擇器顯示了它的10個值。但我的問題是，當我滾動UIPicker，我想，之後的第10行滾動新行應該自動添加填充值。實際上，我在動作表中添加了選擇器。這是我通過它在代碼器中加載數據的代碼。如何增加uipicker的行，當它在iphone
- (void)viewDidLoad
{
currentData = [[NSMutableArray alloc]initWithObjects:@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",nil];
[super viewDidLoad];
}
#pragma mark UIPickerViewDelegate Methods
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
-(NSInteger)pickerView:(UIPickerView*)pickerView numberOfRowsInComponent:(NSInteger)component
{
int count;
if ([pickerType isEqualToString:@"picker"])
{
count = [currentData count];
}
return count;
}
-(NSString*)pickerView:(UIPickerView*)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
NSString *string;
if ([pickerType isEqualToString:@"picker"])
{
NSString *str = @"miles";
//string = [NSString stringWithFormat:@"%d",[currentData objectAtIndex:row],@"%@",str];
string = [NSString stringWithFormat:@"%@" @"%@",[currentData objectAtIndex:row],str];
NSLog(@"%@",string);
}
return string;
}
-(CGFloat)pickerView:(UIPickerView*)pickerView widthForComponent:(NSInteger)component
{
return 300;
}
-(void)pickerView:(UIPickerView*)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
select = YES;
if([barItems objectAtIndex:2]!=0)
{
if ([pickerType isEqualToString:@"picker"])
{
sessoTxt.text = [currentData objectAtIndex:row];
}
}
else{
sessoTxt.text = @"Select";
}
}
如何動態地增加時，它是最後一個數組後滾動選擇器的排value.Thanks
