我有一个文本字段,当我按Enter键时,我的文本字段字符串将发送到textView。每次我在文本字段中输入新行时,它都会使用该字符串并将其附加到textView中。

我需要做的是能够连续键入并按Enter键,将其追加到我的textView中,而无需重新选择textField

在viewDidLoad;

- (void)setupFloatTextBox {
CGFloat screenWidth = [[UIScreen mainScreen] bounds].size.width;
CGFloat screenHeight = [[UIScreen mainScreen] bounds].size.height;

UITextField *noteTextField = [[UITextField alloc] initWithFrame:CGRectMake(5, screenHeight - 55, screenWidth - 5, 30)];
noteTextField.backgroundColor = Rbg2UIColor(51, 182, 124);
[noteTextField.layer setBorderWidth:0.5f];
[noteTextField setAlpha:0.5f];
[noteTextField addTarget:self action:@selector(postJSON:) forControlEvents:UIControlEventEditingDidEnd];
[self.navigationController.view addSubview:noteTextField];
}


和我的选择器动作

- (void)postJSON:(UITextField *)sender {
if (sender.text.length > 0) {
    FireStormClasses *fs = [[FireStormClasses alloc] init];
    fs.CATEGORY = @"TASK";
    fs.TASK = [sender.text substringWithRange:NSMakeRange(3, sender.text.length - 3)];
    fs.WHO = [[sender.text substringToIndex:2] uppercaseString];
    fs.PRIORITY = @"0";
    fs.ACTION = @"UPDATED";
    fs.HIDDEN = @"0";
    fs.UDATE = [FireStorm getCurrentDateWithFormat:@"yyyy-MM-dd"];
    fs.DUEDATE = [FireStorm getCurrentDateWithFormat:@"yyyy-MM-dd"];
    fs.COMPLETEDATE = [FireStorm getCurrentDateWithFormat:@"yyyy-MM-dd"];
    fs.LISTDATE = [FireStorm getCurrentDateWithFormat:@"yyyy-MM-dd"];

    NSURL *URL = [NSURL URLWithString:@"myurl"];
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [manager POST:URL.absoluteString
       parameters:[fs postCreateJSON]
         progress:nil
          success:^(NSURLSessionDataTask *task, id responseObject) {
              NSLog(@"%@", responseObject);
              [self loadJSONData];
          }
          failure:^(NSURLSessionDataTask *task, NSError *error) {
              NSLog(@"%@", [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding]);
              NSLog(@"%@", error);
          }];

    sender.text = @"";
    [sender resignFirstResponder];
    [sender becomeFirstResponder];
} else {
    NSLog(@"Texfield empty");
}
}


我正在使用的sender resignFirstResponder];[sender becomeFirstResponder];行使我的文本字段处于活动状态/非活动状态。

我遇到的问题是,在第一种类型/输入时,我被带回到我的文本字段,在这里我可以继续输入,但是第二次按下Enter键时,该按钮不起作用。

heres a video explaining a bit better(很抱歉导致崩溃,请跳到20秒)

最佳答案

而不是将目标添加到文本字段,只需设置该文本字段的委托,并在UITextfield集合的委托方法中进行设置,

-(void)textFieldDidEndEditing:(UITextField *)textField
{
    [textField becomeFirstResponder];
}


它将解决您的问题
