showing the error

/Users/rajinair/Desktop/xml/apitest/Classes/apicontroller.m: In function ‘-[apicontroller sendRequest]’:

/Users/rajinair/Desktop/xml/apitest/Classes/apicontroller.m:242: warning: initialization makes integer from pointer without a cast

How can solve this.

NSString *json_string = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 

NSDictionary *result = [json_string JSONValue];
NSArray *values = [result objectForKey:@"Result"];
BOOL errortest = [values valueForKey:@"isError"];//initialization makes integer from pointer without a cast
if(errortest == FALSE)
{
    NSLog(@"Valid User");
}
else
{
    NSLog(@"Invalid User");
}

Answer 1

Actually [values valueForKey:@"isError"] returns the string representation of the boolean value(ie., @”YES”). You need to convert it to a bool value by using NSString‘s boolValue method. So,

BOOL errortest = [[values valueForKey:@"isError"] boolValue];
