Cannot set the value of a NSString from another class - ios

Question

I've searched all over google, and stack overflow for a solution, but I wasn't able to find an answer that solved my problem. Sorry for the long post, as I'm trying to give as much information as I can. I'm new to iOS and Objective- c, but not programming in general due to being asked to switch over from Android by my company, so any help is appreciated.
I'm trying to assign a value to an NSString in one class from a TextField in another, but I get the error:
**-[ViewController name:]: unrecognized selector sent to instance 0x78712fe0**
when I run the app in the simulator.
Relevant code:
//UserInfo.h
#import <Foundation/Foundation.h>
#interface UserInfo : NSObject <NSCoding>
#property (nonatomic, strong) NSString *name;
#property (nonatomic, strong) NSString *age;
#property (nonatomic, strong) NSString *address;
#end
//UserInfo.m
#import "UserInfo.h"
static NSString *nameKey = #"userName";
static NSString *ageKey = #"userAge";
static NSString *addressKey = #"userAddress";
static NSString *userInfoKey = #"userInfoKey";
#implementation UserInfo
#synthesize name;
#synthesize age;
#synthesize address;
- (id) initWithCoder:(NSCoder *)coder
{
self = [super init];
self.name = [coder decodeObjectForKey:nameKey];
self.age = [coder decodeObjectForKey:ageKey];
self.address = [coder decodeObjectForKey:addressKey];
return self;
}
- (void)encodeWithCoder:(NSCoder *)coder
{
[coder encodeObject:self.name forKey:nameKey];
[coder encodeObject:self.age forKey:ageKey];
[coder encodeObject:self.address forKey:addressKey];
}

Three breakpoints are set that are supposidly the source of the problem:
From the ViewController.m, in - (void)setUserInterfaceValues
self.nameText.text = self.userInfoObject.name;
(I assume that this applies to the other two lines below it also)
Also from the ViewController.m, in - (void)viewDidLoad
[self setUserInterfaceValues];
And finally from the AppDelegate.m, in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
self.window.rootViewController = self.viewController;
From what I understand, and have learned from searching this issue, the app is trying to send data to something that doesn't exist, the NSString name being the culprit. Others have suggested to make sure that my .xib file is connected to the ViewController, and I have verified that it is.
As another bit of information, I'm not using a storyboard for this app, and instead am using the interface builder. I'm aware that there are advantages to storyboards, and I would like to be using them, but my company uses the interface builder and does a lot of things programmatically, so I'm learning to develop without.
[EDIT]: Issue solved thanks to Ian.
