@Interface __weakIBOutletUITableView *tblView; @property (nonatomic, strong) DataViewCustomCell *prototypeCell;


@Implementation
#pragma mark - PrototypeCell - (DataViewCustomCell *)prototypeCell { if (!_prototypeCell) { _prototypeCell = [[[NSBundlemainBundle]loadNibNamed:@"DataViewCustomCell"owner:selfoptions:nil] lastObject];     } return_prototypeCell; }

Grab the four files (.h and .m) PDKeychainBindingsController folder and add them to your xCode project.Import the header file. #import "PDKeychainBindings.h"
Set object:-
        [[PDKeychainBindingssharedKeychainBindings] setObject:@"Pardeep"forKey:@"key_name"];
Get object from key:-
NSString *folderPath=[[PDKeychainBindingssharedKeychainBindings] objectForKey:@"key_name"];

Remove object:             [[PDKeychainBindingssharedKeychainBindings] removeObjectForKey:@"key_name"];

NOTE:-

If you are getti…
