Can't save and load plist file - ios

Question

When i tried to create plist file('Checklist.plist') using following methods i can't see the file in the directory.
- (NSString *)documentsDirectory {
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths firstObject];
return documentsDirectory; }
- (NSString *)dataFilePath {
return [[self documentsDirectory] stringByAppendingPathComponent:#"Checklists.plist"];
}
Why i can't see the file on the directory? How can i solve this problem?

Answer 1

Did you save something in the file?
NSString *test = #"test";
[test writeToFile:[self dataFilePath] atomically:YES];
If you run this in a simulator, you can NSlog this file path, and than open finder, press cmd + shift + g paste the file path, don't include Checklist.plist, just documents file path, you will see the file you just create named Checklist.plist.
This is all my code:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSArray *testArray = [NSArray arrayWithObjects:#"test", nil];
[testArray writeToFile:[self dataFilePath] atomically:YES];
}
- (NSString *)documentsDirectory {
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths firstObject];
return documentsDirectory;
}
- (NSString *)dataFilePath {
return [[self documentsDirectory] stringByAppendingPathComponent:#"Checklists.plist"];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

The file isn't created when -dataFilePath is called.
To write a plain string in your file, use:
NSError *e = nil;
[#"blabla" writeToFile:[self dataFilePath] atomically:YES encoding:NSUTF8StringEncoding error:&e];
NSError *e1 = nil;
NSString *fileContents = [NSString stringWithContentsOfFile:[self dataFilePath] encoding:NSUTF8StringEncoding error:&e1];
Both errors should be nil and fileContents should contain the original string.
