Iphone 辞职的FirstResponder未按预期工作
我使用uitextfield在uitableview中输入国家值。当点击该字段时,我将显示加载了国家/地区值的tableview 当点击任何单元格时,它返回到相同的形式,并将选定的值添加到“国家”字段中。我的意思是,我将所选的值指定给ViewWillAspect方法中的textfield。在国家/地区字段内设置文本后。我想退出键盘,所以我添加了resignFirstResponder,但它并没有退出键盘 下面是我的代码:Iphone 辞职的FirstResponder未按预期工作,iphone,ios,uitableview,uitextfield,Iphone,Ios,Uitableview,Uitextfield,我使用uitextfield在uitableview中输入国家值。当点击该字段时,我将显示加载了国家/地区值的tableview 当点击任何单元格时,它返回到相同的形式,并将选定的值添加到“国家”字段中。我的意思是,我将所选的值指定给ViewWillAspect方法中的textfield。在国家/地区字段内设置文本后。我想退出键盘,所以我添加了resignFirstResponder,但它并没有退出键盘 下面是我的代码: - (void)textFieldDidBeginEditing:(UI

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.backgroundColor = [UIColor clearColor];
if( indexPath.row == 0 ){
UILabel *aLblTitle = [[UILabel alloc]initWithFrame:CGRectMake(5, 5, 220, 30)];
aLblTitle.backgroundColor = [UIColor clearColor];
aLblTitle.font = [UIFont fontWithName:@"Palatino-Bold" size:16.0];
aLblTitle.text = NSLocalizedString(@"Country","Country");
aLblTitle.textColor = [UIColor whiteColor];
[cell.contentView addSubview:aLblTitle];
myCountryField = [[UITextField alloc]initWithFrame:CGRectMake(133,5,150,30)];
myCountryField.backgroundColor = [UIColor whiteColor];
myCountryField.delegate = self;
myCountryField.borderStyle = UITextBorderStyleRoundedRect;
[cell.contentView addSubview:myCountryField];
}
return cell;
}
希望在添加UITextField委托时以下代码能够正常工作
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[self.myCountryField resignFirstResponder];
return YES;
}
改用这个怎么样:
[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder)
to:nil
from:nil
forEvent:nil];
使用下面的代码,希望它能帮助你
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[self.view endEditing:YES];
return YES;
}
确保您将代表连接到xib文件中的fileowner
。或者在viewDidload
中使用以下代码
yourtextfield.delegate=self;
在.h文件中使用
