我不知道在代码中发生什么事删除特定行的UITableView与故事板。我需要帮助我的代码，我需要一个原因如何错误。如何在Xcode 4.5.2
我选择添加项目链接ChooseViewController在ListViewController 项目列表。我需要删除项目。但我无法删除它。它有调试。

跑吧！响应......
#import <UIKit/UIKit.h>
#import "CTASIAAppDelegate.h"
int main(int argc, char *argv[])
{
@autoreleasepool {

感谢you.for帮助我。 :)
我做过。它同样的错误
#import <UIKit/UIKit.h>
#import "CTASIAAppDelegate.h"
int main(int argc, char *argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([CTASIAAppDelegate class]));
}
}
什么恰巧.......................（TT）
正确的顺序是：首先从模型数组中删除对象，然后调用'deleteRowsAtIndexPaths'。 'reloadData'不是必需的。 –
我做到了。但同样的错误。 –
