一丶切換明文/密文有多余空格

如圖,會有空白;

解決方法

- (IBAction)eyeBtnClick:(UIButton *)sender
{   
   sender.selected = !sender.selected;
   self.pswTextField.secureTextEntry = !sender.selected;
  
  {
  NSString *text = self.pswTextField.text;     
  self.pswTextField.text = @" ";
  self.pswTextField.text = text;
  }
或者

    [self.pswTextField becomeFirstResponder];
}

二 切換到密文狀態(tài),再次編輯時,內(nèi)容清空

重現(xiàn):1.切換明密文狀態(tài),最后在密文狀態(tài),再次編輯,輸入任意字符,內(nèi)容清空;
2.其他textField獲取焦點,再切回來(密文狀態(tài)),內(nèi)容清空

解決方法:

- (IBAction)eyeBtnClick:(UIButton *)sender
{   
   sender.selected = !sender.selected;
   self.pswTextField.secureTextEntry = !sender.selected;

  NSString *text = self.pswTextField.text;     
  self.pswTextField.text = @" ";
  self.pswTextField.text = text;
  
    if (self.pswTextField.secureTextEntry)
    {    
    [self.pswTextField insertText:self.pswTextField.text];   
    }
}
//實現(xiàn)代理<UITextFieldDelegate>
- (void)textFieldDidBeginEditing:(UITextField *)textField
{   
    if (textField == self.pswTextField)   
       {    
          if (textField.secureTextEntry)      
              {         
                   [textField insertText:self.pswTextField.text];       
               }
       }
}
