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:@"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
