显示键盘

[textField becomeFirstResponder];

隐藏键盘

@interface ViewController ()<UITextFieldDelegate>
{
    UITextField  *CSTextField;
}
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    CSTextField =[[UITextField  alloc]initWithFrame:CGRectMake(10, 100, 100, 30)];
    CSTextField.borderStyle=UITextBorderStyleNone;
    CSTextField.tag=10001;
    CSTextField.delegate = self;//指定文本框的代理：
    [self.view  addSubview:CSTextField];
}

#pragma mark---收键盘-----

方式一.点击Return的时候隐藏键盘（需设置TextField的delegate）

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [CSTextField resignFirstResponder];//需指定文本框的代理 CSTextField.delegate = self;
    return YES;
}

方式二.点击view其他区域隐藏键盘

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    //1.直接交出CSTextField的第一响应者的身份
    [CSTextField resignFirstResponder];
    
    
    //2.遍历所有子视图  查找UITextField控件并通知文本失去第一响应者状态
    for (UIView *subVie in self.view.subviews) {
        if ([subVie  isKindOfClass:[UITextField  class]]) {
            [subVie  resignFirstResponder];
        }
    }

    //3.view结束编辑
    [self.view endEditing:YES];
    
    
    //4.keyWindow 结束编辑
    [[[UIApplication sharedApplication] keyWindow] endEditing:YES];
    
    //5.发送resignFirstResponder.
    [[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];
    
    //6.设置textField的Tag
    [[self.view viewWithTag:10001] resignFirstResponder];
}

// Scroll 滑动隐藏
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView
{
    [self.view endEditing:YES];
}
 scrollView.keyboardDismissMode=UIScrollViewKeyboardDismissModeOnDrag;(适用于TableView)

 关于UITextView隐藏键盘

思路基本和UITextField一样

1.方法一

   //1.（结束编辑）
    [self.view endEditing:YES];
    OR
    [self.text endEditing:YES];
    
    //2.（注销第一响应）
    [self.text resignFirstResponder];

2.方法二 （Return）

/**
 *  需设置textView的delegate
 */
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
    if ([text isEqualToString:@"
"]) {
        [textView resignFirstResponder];
        return NO;
    }
    return YES;
}
