我的代码如下:
.h文件中:
@interface TouchLabelViewController : UIViewController<UITextFieldDelegate>
@property (strong, nonatomic) IBOutlet UITextField *aTextField;
-(IBAction)hideKeyboard:(id)sender;
.m文件:
-(IBAction)hideKeyboard:(id)sender{
[(UITextField*)sender resignFirstResponder];
}
后来我还尝试了
.h文件:
- (void)viewDidLoad
{
[super viewDidLoad];
aTextField.delegate = self;
}
@property (strong, nonatomic) IBOutlet UITextField *aTextField;
-(BOOL) textFieldShouldReturn:(UITextField *)textField;
.m文件
-(BOOL) textFieldShouldReturn:(UITextField *)textField{
[aTextField resignFirstResponder];
return YES;
}
但是按返回键的时候,还是不能隐藏键盘啊
-(IBAction)hideKeyboard:(id)sender{
[self. aTextField resignFirstResponder];
[self aaaa];
}
-(void)aaaa{
你要返回按钮做的事情;
}
或者是
-(IBAction)hideKeyboard:(id)sender{
[self aaaa];
你返回按钮要做的事情;
}
-(void)aaaa{
[self. aTextField resignFirstResponder];
}
在.h类中设置:
你的
ViewController : UIViewController
然后在创建TextField的地方delegat:
myTextField.delegate = self;
最后,
-(BOOL) textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return YES;
}
默认执行影响UIModalPresentationFormSheet的可见性,因此为了隐藏键盘要重写:
- (BOOL)disablesAutomaticKeyboardDismissal
{
return NO;
}
使用UITextField中的Delegate:
-(IBAction)hideKeyboard:(id)sender
{
[your_textfield resignFirstResponder];
}
