键盘处理的问题

1.先把框架用cocopods导入或者手动导入项目里面
    platform :ios, '7.0'
    target "放项目的名字" do  双引号里面放的是项目的名字
    pod 'IQKeyboardManager'或者pod 'IQKeyboardManager', '~> 4.0.5'(前面的可以压缩,后面的导入无法压缩)
    end
2.导入头文件 #import "KeyboardManager.h"
3.输入下面代码
   IQKeyboardManager *manager = [IQKeyboardManager sharedManager];
   manager.enable = YES;
   manager.shouldResignOnTouchOutside = YES;
   manager.shouldToolbarUsesTextFieldTintColor = YES;
   manager.enableAutoToolbar = NO;
