在ipad上present 一个 navigation controller 时，present后d出的keyboard，不能够 dismiss 掉。即使 textfIEld resignFirstResponder，keyboard也不会消失。@H_403_10@@H_403_10@

Problem:@H_403_10@@H_403_10@

在iPad keyboard上发现一个问题，当vIEwController在navigation controller下以模态视图d出，并且navigationController.modalPresentationStyle = UIModalPresentationFormSheet时，点击done按钮，软键盘不撤销，即使 textfIEld resignFirstResponder了。@H_403_10@@H_403_10@

Solution:@H_403_10@@H_403_10@

当模态视图在 UINavigationControlle下显示，我们需要设置 navigation controller的disablesautomaticKeyboarddismissal属性，我们可以通过添加类别实现这个。@H_403_10@@H_403_10@

file: UINavigationController+Keyboarddismiss.h@H_403_10@@H_403_10@

#import @H_403_10@@H_403_10@

@interface UINavigationController (Keyboarddismiss)@H_403_10@@H_403_10@

- (BOol)disablesautomaticKeyboarddismissal;@H_403_10@@H_403_10@

@end@H_403_10@@H_403_10@

file: UINavigationController+Keyboarddismiss.m@H_403_10@@H_403_10@

#import "UINavigationController+Keyboarddismiss.h"@H_403_10@@H_403_10@

@implementation UINavigationController(Keyboarddismiss)@H_403_10@@H_403_10@

- (BOol)disablesautomaticKeyboarddismissal@H_403_10@

{@H_403_10@@H_403_10@

    return NO;@H_403_10@@H_403_10@

}@H_403_10@@H_403_10@

@end@H_403_10@@H_403_10@

在需要用到的VIEwController文件中导入创建的类别即可。@H_403_10@@H_403_10@
