Issue with return value after query in Sqlite database - objective-c

Question

In my app I am executing a query to get the count of images which are having same category and that category is passed by me as the parameter. Now when the query is executed I want to get two results either 1 or more than one. For that purpose I think I need to convert the string to integer. When I check the value of the String it is showing me 1 but when that value is returned to the method it is showing something like this:695842 and something else also. What could be the reason? Please help. I am posting the part of code:-
-(NSInteger)searchImagesInSameCategory:(NSString *)categoryName
{
NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory= [paths objectAtIndex:0];
NSString *path=[documentsDirectory stringByAppendingPathComponent:#"SymbolTalkLanguageElement.sqlite"];
//Open the database
//might have to make database as property
if(sqlite3_open([path UTF8String], &dataBase) ==SQLITE_OK)
{
sqlite3_stmt *statement;
NSString *strSQL = [[NSString alloc]init];
strSQL = #"select Count(ImageName) from tblLanguageElement where Category='";
strSQL = [[strSQL stringByAppendingString:categoryName] stringByAppendingString:#"'"];
const char *bar = [strSQL UTF8String];
if(sqlite3_prepare(dataBase, bar, -1, &statement, NULL) == SQLITE_OK)
{
while (sqlite3_step(statement) == SQLITE_ROW)
{
NSLog(#"%#",[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)]);
int k;
//NSString *string=[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)];
//NSLog(string);
k=[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)];
//NSLog([NSString stringWithFormat:#"Count for k:-%d",k]);
//[list addObject:[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)]];
//return [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)];
return k;
}
}
}
return 1;
}

You should use intValue method to convert a NSString to int.
NSString *integerStr = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)];
k = [integerStr intValue];
