Question

I’m writing an application for the iPad that will tell us whether or not someone is on court at a tennis tournament. Basically, just an application with a list of names each with an on/off button next to them. Once the on button is pressed, their name turns red, thus they are on court.

Is there any way, to make this easier for myself, I would be able to connect it to my computer and load in a list of names once the application is complete? That would save me from having to individually enter/modify names manually.

Thanks in advance,
Louis.

Though your question is pretty… vague, one suggestion :

importing Spreadsheet-like data could easily be done by import the .csv version (Comma-separated value) of a Spreadsheet.

A comma-separated values (CSV) file stores tabular data (numbers and
text) in plain-text form. Plain text means that the file is a sequence
of characters, with no data that has to be interpreted instead, as
binary numbers. A CSV file consists of any number of records,
separated by line breaks of some kind; each record consists of fields,
separated by some other character or string, most commonly a literal
TAB or comma. Usually, all records have an identical sequence of
fields.

Example :

Year,Make,Model,Length
1997,Ford,E350,2.34
2000,Mercury,Cougar,2.38

Then, you could simply :

(1) Load your csv file as a simple text file

NSString* contents = [NSString stringWithContentsOfFile:filename
                                               encoding:NSUTF8StringEncoding 
                                                  error:nil];

(2) Get the lines

NSArray* lines = [contents componentsSeparatedByString:@"\n"];

(3) Parse each line’s fields

for (NSString* line in lines)
{
    NSArray* fields = [line componentsSeparatedByString:@","];
}
