当用户单击单元格时，我试图展开视图控制器。我收到错误无法识别的选择器发送到实例...当我单击一个单元格时，我插入的两个 NSLog 没有显示，它只是因该错误而崩溃。这是我的 PrepareForSegue 方法的代码
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSString *pointsPath = [[NSString alloc] initWithFormat:@"totalPoints"];

int totalPoints = [[NSUserDefaults standardUserDefaults]integerForKey:pointsPath];
[[NSUserDefaults standardUserDefaults] setInteger:1 forKey:@"classType"];
if([sender row] == 0)
{
NSLog(@"Chose 0");
if(primaryType > 0)
{
[[NSUserDefaults standardUserDefaults]setInteger:0 forKey:primaryPath];
int newPoints = totalPoints - 1;
[[NSUserDefaults standardUserDefaults]setInteger:newPoints forKey:pointsPath];
[[NSUserDefaults standardUserDefaults] synchronize];
