如何合并两个可变数组?

问题描述

我有一个iPhone应用程序，试图在其中添加两个可变数组.

I have an iPhone application in which i am trying to add two mutable arrays.

NSMutableArray *dataArray = [[NSMutableArray alloc] init];
NSMutableArray *dataArray1 = [[NSMutableArray alloc] init];
NSDictionary *news = [dict objectForKey:@"news"];
NSDictionary *deals = [dict objectForKey:@"deals"];
NSLog(@"%@", [news classForCoder]);
NSLog(@"%@", news);

for (NSDictionary *key in news)
{
    if ([key isKindOfClass:[NSDictionary class]])
    {
        [dataArray addObject:key];
    }
}

for (NSDictionary *key in deals)
{
    if ([key isKindOfClass:[NSDictionary class]])
    {
        [dataArray1 addObject:key];
    }
}

self.newssarray = dataArray;
[self.mTableView reloadData];

在这里，我想将两个数组'dataArray'和'dataArray2'添加到一个数组(self.newsarray)中.有人可以帮助我实现这一目标吗?

Here I want to add the two arrays 'dataArray' and 'dataArray2' to be combined into one array (self.newsarray). Can anybody help me in achieving this?

推荐答案

NSMutable数组具有NSArray的所有方法，包括一种通过向其自身添加另一个数组来创建新数组的方法:

NSMutable array has all of NSArray's methods, including one for creating a new array by adding another array to itself:

self.newsarray = [[dataArray arrayByAddingObjectsFromArray:dataArray1] mutableCopy];
