ios - 检索阵列时本地存储崩溃

我不明白为什么我的应用崩溃了，如何避免崩溃，

在.h中

  @property (nonatomic)  NSArray * PersonsFromSearch;

在.m中

碰撞区

 viewDidLoad
NSArray* nameArr;
   if([defaults objectForKey:@"Person1"])
   {
       nameArr = [NSArray arrayWithObjects: [defaults objectForKey:@"Person1"],Nil];//ate
       PersonsFromSearch = nameArr;//crashes here  :(
       NSLog(@"not crashed yet");
   }

以相同的文件分配到本地存储

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [self dismissKeyboard];
    //test solution :)
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];//store it !
    [defaults setObject:[PersonsFromSearch objectAtIndex:indexPath.row]     forKey:@"Person1"];//store 1 person Full details
    [[NSUserDefaults standardUserDefaults] synchronize];//store indeed
    //keep with code
}

*首先抛出调用堆栈:

最佳答案

使用PersonsFromSearch =[NSArray arrayWithArray:nameArr];
