I want to fetch a plist file from a ser开发者_运维知识库ver and open it within the app.

Does there need to be a php web client on the server or how would this be done, keeping security in mind to?

with this You can fetch file content in a string.

NSURL *address = [NSURL URLWithString:@"http://yourwebsite.com/file.plist"];
    NSString *fileString = [NSString stringWithContentsOfURL:address encoding:NSUTF8StringEncoding error:nil];

after fetching you can display this content in UITextView.

[youtextview setText:fileString];
