Question

I use this method to access my mysql database from Xcode:

NSString *URL = [NSString
stringWithFormat:@”http://test.test:8888/test/loadUserData.php?username=%@”,
userName];

NSString *rawJSON = [[NSString alloc]
initWithContentsOfURL:[NSURL
URLWithString:URL]];

const char *convert = [rawJSON
UTF8String]; NSString *responseString
= [NSString stringWithUTF8String:convert];

if ([rawJSON length] == 0) {
[rawJSON release];

}

SBJsonParser *parser = [[SBJsonParser
alloc] init];

userInfo = [[parser
objectWithString:responseString
error:nil] copy]; SSN = [userInfo
objectAtIndex:0];

[parser release];

return userInfo;

Everything works great. EXCEPT that I can’t compare strings in the result with normal nsstrings. If I say

if ([userinfo objectAtIndex:0) == @”Dan”)
{
..do something
}

Xcode never sees that it is the same value..
I don’t know if there is something wrong with the format (My database is UTF-8)
And how can I convert the result so xCode can compare the response with NSStrings?

Thanks!

Answer 1

== does not compare the value of strings, it just compares their addresses.

Use

if ([[userinfo objectAtIndex:0] isEqualToString:@"Dan"]) { ... } 

or something similar instead.
