Question

For example [request responseString]’s value sent by my servlet to my iphone application is “myinfo”. In my iphone application, I made a string like this:

 NSString *str = @"myinfo";

then i have if else

 if([responseString isEqualToString:str]){
    NSLog(@"condition true");

}else{
        NSLog(@"condition false");
}

in console its always showing “condition false”. Whats the problem? Isn’t isEqualToString is write method to check if strings are equal or not? Thanks in advance.

The NSString method isEqualToString is the correct thing to use here. You can do a sanity check by adding a log to your method:

NSLog(@"responseString = %@",responseString);
NSLog(@"str = %@",str);

if([responseString isEqualToString:str]){
    NSLog(@"condition true");

}else{
    NSLog(@"condition false");
}

Remember that NSStrings are Case Sensitive, so the two strings must appear exactly the same.
