代碼:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return [self.colorNames count];
}
是什麼的tableView?請顯示相關代碼。 – MByD 2011-06-01 14:24:58
它似乎被卡住的代碼是: ' - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {self.colorNames count]; }' – 2011-06-01 14:29:11
請編輯該問題,不要在評論中添加此內容。 – MByD 2011-06-01 14:30:55
