废话不多说直接上代码，一个appDelegate的分类方法

#import "AppDelegate.h"@interface AppDelegate (DismissKeyboard)/** 开启点击空白处隐藏键盘功能 */- (void)openTouchOutsideDismissKeyboard;@end@implementation AppDelegate (DismissKeyboard)/** 开启点击空白处隐藏键盘功能 */- (void)openTouchOutsideDismissKeyboard{    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(addGesture) name:UIKeyboardDidShowNotification object:nil];}- (void)addGesture{    [self.window addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(disappearKeyboard)]];}- (void)disappearKeyboard{    [self.window endEditing:YES];    [self.window removeGestureRecognizer:self.window.gestureRecognizers.lastOb ject];}- (void)dealloc{    [[NSNotificationCenter defaultCenter]removeObserver:self];}@end

在AppDelegate.m 中 #import "DismissKeyboard.h"
在 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 加上[self openTouchOutsideDismissKeyboard];

附带创建方法：

分类方法

使用calloc分配的函数内存需要手动释放
