Question

I got a question how i can count items in my plist file. I tried:

NSString *bundlePathofPlist = [[NSBundle mainBundle]pathForResource:@"Mything" ofType:@"plist"];

    NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:bundlePathofPlist];

    NSArray *dataFromPlist = [dict valueForKey:@"some"];

    for(int i =0;i<[dataFromPlist count];i++)
    {
        //NSLog(@"%@",[dataFromPlist objectAtIndex:i]);
        [self setTableData:[dataFromPlist count]];

    }

    NSLog(@"%@", tableData);

But on this line an error appears:

    [self setTableData:[dataFromPlist count]];

Implicit conversion of 'NSUInteger' (aka 'unsigned int') to 'NSArray *' is disallowed with ARC

and warning:

Incompatible integer to pointer conversion sending 'NSUInteger' (aka 'unsigned int') to parameter of type 'NSArray *'; 

Answer 1

It looks like your setTableData takes an NSArray instance. You need to prepare an array upfront in a loop, and then set it once, like this:

NSMutableArray *data = [NSMutableArray array];
for(int i =0;i<[dataFromPlist count];i++)
{
    //NSLog(@"%@",[dataFromPlist objectAtIndex:i]);
    [data addObject:[NSNumber numberWithInt:[[dataFromPlist objectAtIndex:i] count]]];
}
[self setTableData:data];

This assumes that your setTableData method expects an array of NSNumber instances wrapping ints.
