ios键盘隐藏

方法一：在button按钮的点击事件中加上[self.textFiled resignFirstResponder]; 

方法二： 

在xib文件中，可以不在View页面上添加一个View控件 ,一个简单的办法是将View页面的类设置为UIControl(该类继承与UIView)

 

.h文件：

#import <UIKit/UIKit.h>

@interface HomeViewController : UIViewController

@property (retain, nonatomic) IBOutlet UITextField *nameField;

@property (retain, nonatomic) IBOutlet UITextField *passwordField;

- (IBAction)textFieldDoneEditing:(id)sender;

- (IBAction)backgroundTap:(id)sender;

@end

 .m文件：

 

 

#import "HomeViewController.h"

@interface HomeViewController ()

@end

@implementation HomeViewController

 

@synthesize nameField;

@synthesize passwordField;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {

        // Custom initialization

    }

    return self;

}

- (void)viewDidLoad

{

    [super viewDidLoad];

    // Do any additional setup after loading the view from its nib.

}

- (void)viewDidUnload

{

    [self setNameField:nil];

    [self setNameField:nil];

    [self setPasswordField:nil];

    [super viewDidUnload];

    // Release any retained subviews of the main view.

    // e.g. self.myOutlet = nil;

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

    return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

- (void)dealloc {

    [nameField release];

    [nameField release];

    [passwordField release];

    [super dealloc];

}

- (IBAction)textFieldDoneEditing:(id)sender {

    [sender resignFirstResponder];

    

}

- (IBAction)backgroundTap:(id)sender {

    [nameField resignFirstResponder];

    [passwordField resignFirstResponder];

}

@end
