iOS应用程序崩溃，无法找到方案

Question

运行我的应用程序时，它崩溃，我没有看到我的代码有问题。请帮我找到这个问题。

这是didSelectRow中方法UITableViewDelegate中的代码，它崩溃了：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[[SingletonClass SharedMethod] setGlobalAddSubjectResueIdentifier:@"ForListDetails"];
[self.tblSearchHolder deselectRowAtIndexPath:[self.tblSearchHolder indexPathForSelectedRow] animated:YES];

NSDictionary *dictGGetSelectedVal=[arrLoadDataTemp objectAtIndex:indexPath.row];
[[SingletonClass SharedMethod] setGlobalSelectedSearchProperty:dictGGetSelectedVal];

arrGetValForTable=nil;
arrLoadDataTemp=nil;

[[SingletonClass SharedMethod] setGlobalHolder:@"addPropertyScene"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"ChangeViewsAsPerCriteria" object:nil];

}

崩溃报告本身：

Answer 1

好吧，它很容易找到（有点运气:)）。

1. 首先，尝试按如下方式启用NSZombie对象：

2. 尝试按如下方式设置异常断点（确保您在断点的选项卡上）：

祝你好运，编码愉快！ :)
