How to check my NSString is exist in my NSMutableOrderedSet?

Question

I am getting below response from the one of the third party SDK, Now how to check that my String value is exist in the response? And the key I need to compare with friendlyName key.

 channelList = (
     "<<TCHChannel: 0x2816df040>: sid: 'CH84', friendlyName: 'Mihir : MihirOza', attributes: '(null)'>",

     "<<TCHChannel: 0x2816dc480>: sid: '644d', friendlyName: 'Testchannel2', attributes: '(null)'>",

     "<<TCHChannel: 0x2816dff40>: sid: 'df38', friendlyName: 'privateios', attributes: '(null)'>" )  

Here is the code which I am using.

TCHChannels *channelsList = [[[ChatManager sharedManager] client] channelsList];
NSMutableOrderedSet<TCHChannel *> *newChannels = [[NSMutableOrderedSet alloc] init];
[newChannels addObjectsFromArray:[channelsList subscribedChannels]];
NSMutableArray<TCHChannel *> *temp = [[NSMutableArray alloc] initWithArray:[newChannels array]];
NSLog(@"channelList = %@",temp);

Thanks in advance.

Try This :

NSPredicate *Pred = [NSPredicate predicateWithFormat:
                          @"TCHChannel.friendlyName == 'yourstring'"];
NSArray *arr = [temp filteredArrayUsingPredicate:pred];

Try below code

NSMutableArray<TCHChannel *> *temp = [[NSMutableArray alloc] initWithArray:[newChannels array]];
NSLog(@"channelList = %@",temp);

NSPredicate *Pred = [NSPredicate predicateWithFormat:
                          @"friendlyName == 'yourMatchString'"];
NSArray *arr = [temp filteredArrayUsingPredicate:pred];
