NSArray add objects from other array
提问by Matrosov Alexander
I have three NSArrayobjects. I need to add all objects for this array to NSArraythat is called allMyObjects.
我有三个NSArray对象。我需要将此数组的所有对象添加到NSArray名为allMyObjects 的对象中。
Have NSArraystandard solution to make it for example via initialization method or do I need make custom method to retrieve all objects from other arrays and put all retrieved objects to my allMyObjectsarray?
有NSArray标准的解决方案，例如通过初始化方法来实现它，还是我需要自定义方法来从其他数组中检索所有对象并将所有检索到的对象放入我的allMyObjects数组？

Don't know if this counts as a sufficiently simple solution to your problem, but this is the straight forward way to do it (as alluded to by other answerers, too):
不知道这是否可以作为解决您问题的足够简单的方法，但这是最直接的方法（正如其他回答者所暗示的那样）：
NSMutableArray *allMyObjects = [NSMutableArray arrayWithArray: array1];
[allMyObjects addObjectsFromArray: array2];
[allMyObjects addObjectsFromArray: array3];

once see this one ,
一旦看到这个，
NSArray *newArray=[[NSArray alloc]initWithObjects:@"hi",@"how",@"are",@"you",nil];
NSArray *newArray1=[[NSArray alloc]initWithObjects:@"hello",nil];
NSArray *newArray2=[[NSArray alloc]initWithObjects:newArray,newArray1,nil];
NSString *str=[newArray2 componentsJoinedByString:@","];
NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"()\n "];
str = [[str componentsSeparatedByCharactersInSet:doNotWant] componentsJoinedByString: @""];
NSArray *resultArray=[str componentsSeparatedByString:@","];
NSLog(@"%@",resultArray);
O/P:-
开/关：-
(
hi,
how,
are,
you,
hello
)

You can call addObjectsFromArray:method on your allMyObjectsarray.
您可以addObjectsFromArray:在allMyObjects数组上调用方法。

Here am adding code for store and get datas from array to array.
这里添加了用于从数组到数组存储和获取数据的代码。
To store array to array
将数组存储到数组
NSMutableArray rowOneRoundData = [NSMutableArray arrayWithObjects: @"45",@"29",@"12",nil];
NSMutableArray rowTwoRoundData = [NSMutableArray arrayWithObjects: @"41",@"45",@"45",nil];
NSMutableArray rowThreeRoundData = [NSMutableArray arrayWithObjects: @"12",@"45",@"22",nil];
NSMutableArray rowFourRoundData = [NSMutableArray arrayWithObjects: @"45",@"12",@"61",nil];
NSMutableArray rowFiveRoundData = [NSMutableArray arrayWithObjects: @"12",@"14",@"14",nil];
NSMutableArray rowSixRoundData = [NSMutableArray arrayWithObjects: @"12",@"12",@"12",nil];
NSMutableArray rowSevenRoundData = [NSMutableArray arrayWithObjects: @"12",@"36",@"83",nil];
NSMutableArray rowEightRoundData = [NSMutableArray arrayWithObjects: @"37",@"57",@"45",nil];
NSMutableArray rowNineRoundData = [NSMutableArray arrayWithObjects: @"12",@"93",@"83",nil];
NSMutableArray rowTenRoundData = [NSMutableArray arrayWithObjects: @"16",@"16",@"16",nil];
NSArray circleArray = [[NSArray alloc]initWithObjects:rowOneRoundData,rowTwoRoundData,rowThreeRoundData,rowFourRoundData,rowFiveRoundData,rowSixRoundData,rowSevenRoundData,rowEightRoundData,rowNineRoundData,rowTenRoundData, nil];
Get data from Circle Array

for (int i= 0; i<10;i++)
{
NSArray *retriveArrar = [[circleArray objectAtIndex:i] mutableCopy];
}
