xcode iOS compare strings

if (webresult == cmp)

Here, == checks whether webresult, cmp are pointing to the same reference or not. You should instead compare value of the object by using NSString::isEqualToString.

 if ( [ cmp isEqualToString:webresult ]) {
   // ..
 }else {
   // ..
 }

Note that isEqualToString is a good option because it returns boolean value.

I assume that webresult is an NSString. If that is the case, then you want to use:

if ([webresult isEqualToString:cmp]) {

instead of:

if (webresult == cmp) {

as the above method checks if the strings are equal character by character, whereas the bottom method checks if the two strings are the same pointer. Hope that helps!

We cannot comapre the strings with ==
We have to use isEqualToString:

if([str1 isEqualToString:str2])
{
}
else
{
}
