NSMutableArray of nsstrings (in one of the UISearchBar delegates) possible with persistent storage?
I would like to make a history list in my app. I have surfed and looked at many questions here, but so far I haven´t found the answer to my question.
My codes:
-(void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
NSLog (@"search bar text did end editing!");
NSString *bookmarked = mySearchBar.text;
NSMutableArray *bookmarkl = [[NSMutableArray alloc] init];
int i;
for (i = 0; i < [bookmarkl count]; i ++)
{
[bookmarkl addObject:bookmarked];
}
for (NSString *sa in bookmarkl);
NSLog (@"whole array: %@", bookmarkl开发者_开发知识库);
}
But all I get is one string at a time. What is wrong? I want to add a new string to the mutable array, how should I do this?
You are creating a new list every time the function is called. You should add bookmarkl to your class as a property and only create it once during initialization. If you want the history to persist when your app is closed you will also want to write the data to a file. You can use [NSMutableArray arrayWithContentsOfFile] to load the history and writeToFile to save it.
