Answer 1

you can use containsObject method in an NSMutableArray

if ([yourArray containsObject:@"object"]) {
    [yourArray removeObject:@"object"];
}

Swift:

if yourArray.contains("object") {
    yourArray = yourArray.filter{ $0 != "object" } 
}

Answer 2

[array removeObject:@"Name2"];

The documentation for NSMutableArray’s removeObject: method states:

matches are determined on the basis of an object’s response to the isEqual: message

In other words, this method iterates over your array comparing the objects to @"Name2". If an object is equal to @"Name2", it is removed from the array.
