I would like to know how to compare a string with an array, i.e., if my array list has {"abc", "pqr", "xyz"} and the new string lets say "mno" is typed, it should compare with my previous array list. How can I do this? Thanks in advance.

Look at the NSArray documentation...
BOOL hasString = [your_array containsObject:your_string];

can we use it in if condition

@sameer, yes you can:
if ([your_array containsObject:your_string]) {}

This is only a good solution if you are not interested in the actual string contents - which is usually not the case. The containsObject call uses isEquals to compare each item.

@crow, you're the only one that took this into account. I was actually looking for a way to invoke isEqualToString in a similar way, but later realised that isEqual is enough for me in current scenario. However, I'm interested in a clean solution with isEqualToString, just out of curiosity. Do you know how we can achieve that?
System:
if ([yourArray containsObject:yourNSString])
{
NSLog(@"Bingo!");
}
Manual:
for (int i = 0 ; i < [yourArray count] ; i++) {
if ([yourNSString isEqualToString:[yourArray objectAtIndex:i]]) {
NSLog(@"Bingo!");
break;
}
}

for(int i=0; i<[myarray length]; ++i) {
if([myarray[i] isEqualToString:@"mno"])
NSLog("Equal");
else NSLog("Not Equal");
}

Here is a working (tested) method,
-(BOOL)checkStingInArray: (NSString *)aString arrayWithStrings:(NSMutableArray *)array
{
if ( [array containsObject: aString] ) {
NSLog(@" %@ found in Array",aString );
return YES;
} else {
NSLog(@" %@ not found in Array",aString );
return NO;
}
}
