IOS: check a plist file

Question

I have this code: for the simulator to write a NSmutableArray in a plist

 NSString *path = [[NSBundle mainBundle] pathForResource: @"Array" ofType:@"plist"];

if([Array writeToFile:path atomically: YES]){
    NSLog(@"write succesful");}
else {
    NSLog(@"write failed");
}

but how I can check if really the file plist is empty?

do you have problems writing the file? or do you want to read it? — Deepak Danduprolu, May 20 '11 at 14:50

Although this code works in the iOS Simulator, you will not be able to write into your app bundle on iOS devices.

You would probably want to write to the documents folder: `[[[NSFileManager defaultManager] URLsForDirectory: NSDocumentDirectory inDomains: NSUserDomainMask] lastObject]` – Alexsander Akers May 20 '11 at 14:51

Write the file.

[[NSFileManger defaultManager] createFileAtPath:path contents:plistData withAttributes:attributesDictionary];

Check the file for the array.

NSDictionary *infoDictionary = [NSDictionary dictionaryWithContentsOfFile:path];
if ([infoDictionary count] == expectedIntegerValue) {
  NSLog(@"Success");
  if ([infoDictionary objectForKey:@"ARRAY_KEY"]) {
    NSLog(@"Found the array!");
  } else {
    NSLog(@"No Array Found.");
  }
} else {
  NSLog(@"Fail");
}

if you just want to know if there are any keys [infoDictionary count] > 0.

I want to know exactly how I can write an array in a plist file and check if inside this file there is the array, but NOT for the simulator. – cyclingIsBetter May 20 '11 at 15:00
oops shoot, forgot the code to write to a file not in the main bundle. Just a minute. – Kyle May 20 '11 at 15:07
