display variable value in UITextField by iOS, Objective-c - ios

Question

Data I need to displayed has been stored into a temp file.When I execute the application, NSLog can receive the data, but UITextField didn't respond. I don't know if I am using the correct syntax. And I am not sure why it doesn't work...
Update: I tried to assign a value to UItextField, but the UItextField doesn't display it neither
-(void)readFilewin
{
// ....
NSString *pathsWin;
NSArray *pathsWin1= NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
pathsWin = [[pathsWin1 objectAtIndex:0] stringByAppendingPathComponent:#"arraycountwin.plist"];
NSArray *getfile = [NSArray arrayWithContentsOfFile:pathsWin];
//NSArray *getfile = [NSArray arrayWithContentsOfFile:#"arraycountwin.plist"];
//self.TotalWinTextField.text = [getfile objectAtIndex:0];
NSString * win = [[NSString alloc]init];
win = [getfile objectAtIndex:0];
NSLog(#"Win : %#", win);
self.TotalWinTextField.text = [NSString stringWithFormat:#"%#", win];
}
-(void)readFileLoss{...}
-(void)readFilestats
{
// ....
NSString *statspath;
NSArray *statspaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
statspath = [[statspaths objectAtIndex:0] stringByAppendingPathComponent:#"arraystats.plist"];
NSArray *getfile = [NSArray arrayWithContentsOfFile:statspath];
NSString * time = [[NSString alloc]init];
time = [getfile objectAtIndex:0];
NSLog(#"Time : %#", time);
NSString * time1 = [[NSString alloc]init];
time1 = [getfile objectAtIndex:1];
NSLog(#"Time1 : %#", time1);
self.textField1.text = time; //broke here after update the viewDidLoad as #paul11 advise
self.textField2.text = time1;
}
Update for testing purpose to make sure the textfield is working, but it cannot even read the assigned value:
- (void)readFilewin
{
self.TotalWinTextField.text = #"23"; //DONT WORK
}

Answer 1

I think you forgot to reference UITextField in the storyboard with your property
#property (weak, nonatomic) IBOutlet UITextField *totalWinTextField;
that is easy you just need to select your UITextField in the storyboard holding down the key control and you drag it to your property. You can see when the property is referenced when in the left side has a circle filled.
I hope to be helpful.

From your comment, this is your viewDidLoad -
- (void)viewDidLoad {
//win
self.TotalWinTextField = 0;
//loss
self.TotalLossTextField = 0;
//stats
self.textField1 = 0;
self.textField2 = 0;
self.textField3 = 0;
[self readFilewin];
[self readFilelose];
[self readFilestats];
}
This is setting all of your IBOutlets to nil (0).
I presume that what you meant was -
- (void)viewDidLoad {
//win
self.TotalWinTextField.text = #"0";
//loss
self.TotalLossTextField.text = #"0";
//stats
self.textField1.text = #"0";
self.textField2.text = #"0";
self.textField3.text = #"0";
[self readFilewin];
[self readFilelose];
[self readFilestats];
}

First of all make sure that outlet is created correctly
Secondly, check it is properly synthesized
thridly, make sure outlet is nonatomic
change ur viewDidLoad to this
- (void)viewDidLoad {
// Do any additional setup after loading the view.
[super viewDidLoad];
//win self.TotalWinTextField = 0;
//loss self.TotalLossTextField = 0;
//stats self.textField1 = 0;
self.textField2 = 0;
self.textField3 = 0;
[self readFilewin];
[self readFilelose];
[self readFilestats];
}
