NSMutableArray 添加对象有限制吗？

Question

我正在使用 NSMutableArray 添加 objects.But 它只添加前 10 个对象。我有分享代码

  for (int j = 0; j<[feedData count]; j++)
    {

       [sharingItems addObject:[self whatsappdata:[feedData objectAtIndex:j]]];

    }

此方法return NSString 键入文本。

请为此提供有效的解决方案。

提前致谢

      -(NSString *)whatsappdata:(NSDictionary *)cellData1
      {

NSString *brandName = [NSString stringWithFormat:@"%@", [cellData1 objectForKey:@"brand_name"]];
NSString *modelName = [NSString stringWithFormat:@"%@", [cellData1 objectForKey:@"brand_model_name"]];

NSString *version = [NSString stringWithFormat:@"%@", [cellData1 objectForKey:@"version_name"]];
if ([version  isEqualToString: @"<null>"])
{
    version = @"";
}
NSString *year = [NSString stringWithFormat:@"%@", [cellData1 objectForKey:@"model_year"]];
if (year == nil || [year isEqualToString:@"0"])
{
    year = @"";
}
NSString *inventoryValue = [NSString stringWithFormat:@"%@",[cellData1 objectForKey:@"inventory_type"]];
NSInteger value = [inventoryValue intValue];
NSString *inventoryName;
NSString *msg;
if(value == 1)
{
    inventoryName = [NSString stringWithFormat:@"%@", @"Stock"];
    i++;
    NSString *text2 = [NSString stringWithFormat:@"%d.%@ %@ %@- %@ Single Owner\n",i, brandName, modelName, version, year];
    msg = [NSString stringWithFormat:@"%@",text2];
    msg= [msg  stringByReplacingOccurrencesOfString:@"\n" withString:@"<br/>"];
}
else
{
    inventoryName = [NSString stringWithFormat:@"%@", @"Required"];
    msg = @"";
}



return msg;
//end data

   }

添加元素前需要给数组分配内存

sharingItems = [[NSMutableArray alloc]init];

Answer 2

很可能“获取限制”已经为'NSFetchRequest[=17=设置了]' 在您的代码中。

NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setFetchLimit:10];//such code you need to find and remove/change fetch limit
