how to compare two NSMutableArray?

Question

How can I compare two NSMutableArray ? if both are same than it should return true otherwise false.

Thanks...

Answer 1

Should be able to use the NSArray base class to compare one array with another array:

- (BOOL)isEqualToArray:(NSArray *)otherArray

Answer 2

[array1 isEqualToArray:array2];

Answer 3

return ([array1 isEqualToArray:array2]);

returns YES if arrays are equal else returns NO

Answer 4

Use isEqualToArray: method to compare between two array object

like this :

Method 1:

return [array1 isEqualToArray:array2]; //return YES or NO

Method 2:

if([array1 isEqualToArray:array2]) {//perform condition on YES}

Answer 5

if([array1 isEqualToArray:array2]){

   }else{

   }

Answer 6

Does isEqualToArray: method help you?

Other way is to iterate through both arrays and compare each object using isEqual: method. It is the same to calling isEqualToArray:. Note that in both variants you should implement isEqual: method in your array object class if it in not a standard class.

And right before this operations you can just compare their length, if they are not equal so there is no point of spending resources on more complicated calculations.
