苹果开始拒绝我的应用（经过数年的批准）-我有2个文本字段的几个字符的姓，名，然后按Go键。他们声称--我无法重现只按Go键时应用程序崩溃的情况--当我运行应用程序时，它试图发送请求，但返回错误信息“没有名字-请重新输入”。不管怎样。为了安抚苹果，我把文本字段输入方式修改成现在的样子（见下文）-但仍然不工作。请指示。

// Text Field methods

-(void)textFieldDidBeginEditing:(UITextField *)textField {
    
    UIFont* boldFont = [UIFont fontWithName:@"Helvetica-Bold" size: 24];
    
    if (textField == _lastName) {
        [_lastName becomeFirstResponder];
        [_lastName setFont:boldFont];
        _lastName.autocorrectionType = UITextAutocorrectionTypeNo;;
        _lastName.autocapitalizationType = UITextAutocapitalizationTypeNone;
        _lastName.text = @"";
        
        NSLog(@"user editing last...");
        
        // Enable button once fields have values
            
        if ([_lastName.text isEqual: @""] && [_firstName.text  isEqual: @""])
            {
                _fwdButton.enabled = YES;
            }
        
    }
    
    else {
        [_firstName becomeFirstResponder];
        [_firstName setFont:boldFont];
        _firstName.autocorrectionType = UITextAutocorrectionTypeNo;;
        _firstName.autocapitalizationType = UITextAutocapitalizationTypeNone;
        _firstName.text = @"";
        
        NSLog(@"user editing first");
        
        // Enable button once fields have values
            
        if ([_lastName.text isEqual: @""] && [_firstName.text  isEqual: @""])
            {
                _fwdButton.enabled = YES;
            }
    }
