为什么我的UITextField委托方法没有被调用？

Question

这是我的问题.我创建了一个UITextField.

.h文件:

@property (strong, nonatomic) UITextField *emailTextField;

.m文件:

- (void)viewDidLoad
{
  [super viewDidLoad];
  self.emailTextField.delegate=self;
  [self setTextFields:120 :@"  email" :self.emailTextField];
}

-(void)setTextFields:(float)ycoord :(NSString *)text :(UITextField *)textField
{
  CGRect frame = CGRectMake(60, ycoord, 180, 30);
  textField = [[UITextField alloc]initWithFrame:frame];
  textField.backgroundColor = [UIColor whiteColor];
  textField.placeholder = text;
  textField.font = [UIFont fontWithName:@"Baskerville" size:15];
  textField.allowsEditingTextAttributes=YES;
  textField.autocorrectionType = UITextAutocorrectionTypeNo;

  CALayer *lay = [textField layer];
  [lay setCornerRadius:5.0f];
  [self.view addSubview:textField];
}

目的是保存用户放在TextField中的文本.我尝试了委托方法

-(void)textFieldDidEndEditing:(UITextField *)textField

但是没有调用该方法(我把一个NSLog检查).有人可以帮忙吗？

- (void)viewDidLoad
 {
  [super viewDidLoad];

  self.emailTextField= [self setTextFields:120 :@"  email"];
  self.emailTextField.delegate=self;

  self.passwordTextField= [self setTextFields:200 :@"  password"];
  self.passwordTextField.delegate=self;

  self.nameTextField= [self setTextFields:250 :@"  name"];
  self.nameTextField.delegate=self;
 }

-(UITextField *)setTextFields:(float)ycoord :(NSString *)text{

  CGRect frame = CGRectMake(60, ycoord, 180, 30);

  UITextField* textField = [[UITextField alloc]initWithFrame:frame];
  textField.backgroundColor = [UIColor whiteColor];
  textField.placeholder = text;
  textField.font = [UIFont fontWithName:@"Baskerville" size:15];
  textField.allowsEditingTextAttributes=YES;
  textField.autocorrectionType = UITextAutocorrectionTypeNo;

  CALayer *lay = [textField layer];
  [lay setCornerRadius:5.0f];
  [self.view addSubview:textField];
  return textField;
  }
