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
