    well I am new to iPhone develop.
    Recently, I try to do some tableview application,and I follow the book`s example, but I met some problem.

    In the .h file I use the two protocol <UITableViewDelegate, UITableViewDataSource>.
    The problem is when I try to type the two functions numberOfRowInSection and cellForRowAtIndexPath,
    it doesn`t work, and the xcode show me “NO Completions found”.

    Then , compile with some warning, just like the puctures below:



    It is ridiculous that when I try to paste the book`s example code into my .m file, it is works magically!

    I compare the two codes which are the book`s example and I type, anything different is not find.

    The question bother me, and I can`t find how to handle it,
    please tell me why and how to solve it, THX

    and the project file is below:

    Xcode doesn't always spot all potential autocompletions — it's a helpful tool but it isn't authoritative. Just type the whole name for yourself.

    Looking at the project you attached, you've named your method:

    -(NSInteger)tableView:(UITableView *) tableView numberOfRowInSection :(NSInteger)section{
    When it should be:

    -(NSInteger)tableView:(UITableView *) tableView numberOfRowsInSection :(NSInteger)section{
    i.e. rows is plural. You've made a typo, but the fact that Xcode didn't guess the correct autocompletions isn't relevant.
