Question

mainstr is my string contains:

 123;456;23;ns@234;343;3;ner@975;013;742;av@ 

arr is my array name.

each location of array contains some string like (should be separated by @)

arr[0]=[123;456;23;ns];

arr[1]=[234;343;3;ner];

I want to separate each element of arr[0] into separate array (they should be separated based on occurrence of ;
)..

for example

newarray[0]=[123] 

newarray[1]=[23]

newarray[2]=[45]

newarray[3]=[ns]

how should I do this ?

Answer 1

You can use the firstly

NSArray *stringArray = [mainstr componentsSeparatedByString:@"@"];

then you can use

NSArray *arr0 = [[stringArray objectAtIndex:0] componentsSeparatedByString:@";"];
and so on...
