IQKeyboardManager 支持 CocoaPods

pod ‘IQKeyboardManager’

管理

UINavigationBar

如果你不使用storyboardxib创造你的视图。你需要重写-(void)UIViewController loadview方法,需要设置一个UIScrollView实例self.view

-(void)loadView    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];   self.view = scrollView; }

为某一个ViewController禁用IQKeyboardManager

如果你想在某个 viewcontroller 禁用 IQKeyboardManager 你应该在 ViewDidAppear 中禁用IQKeyboardManager,而在ViewWillDisappear启用它 
代码:

 #import "IQKeyboardManager.h" @implementationExampleViewController     BOOL _wasKeyboardManagerEnabled;   }-(void)viewDidAppear:(BOOL)animated{    [super viewDidAppear:animated];    _wasKeyboardManagerEnabled = [[IQKeyboardManager sharedManager] isEnabled];    [[IQKeyboardManager sharedManager] setEnable:NO];}-(void)viewWillDisappear:(BOOL)animated{    [super viewWillDisappear:animated];    [[IQKeyboardManager sharedManager] setEnable:_wasKeyboardManagerEnabled];   @end 

键盘的回车键处理

1)创建一个实例变量实例化IQKeyboardReturnKeyHandler 在 ViewController 的 viewDidLoad 中

代码:

@implementationViewController  {     IQKeyboardReturnKeyHandler *returnKeyHandler; }- (void)viewDidLoad{    [super viewDidLoad];    returnKeyHandler = [[IQKeyboardReturnKeyHandler alloc] initWithViewController:self];}

改变键盘上的返回键。

设置实例变量为零的dealloc方法
-(void)dealloc {    returnKeyHandler = nil;}

UIToolbar(IQToolbar)

1)如果你不想添加一个特定的自动工具栏在键盘上方,应该添加一个类作为它的工具栏
textField.inputAccessoryView = [[UIView alloc] init];
2)如果你需要自己控制上/下/完成按钮,那么应该使用UIView类的方法,创建你的文本框工具栏。

代码:

-(void)viewDidLoad{   [super viewDidLoad];      //Adding done button for textField1   [textField1 addDoneOnKeyboardWithTarget:self action:@selector(doneAction:)];     //Adding previous/next/done button for textField2   [textField2 addPreviousNextDoneOnKeyboardWithTarget:self previousAction:@selector(previousAction:) nextAction:@selector(nextAction:) doneAction:@selector(doneAction:)];     //Adding cancel/done button for textField3   [textField3 addCancelDoneOnKeyboardWithTarget:self cancelAction:@selector(cancelAction:) doneAction:@selector(doneAction:)];    /*! previousAction. */  -(void)previousAction:(id)button   //previousAction     /*! nextAction. */  -(void)nextAction:(id)button   //nextAction     /*! doneAction. */  -(void)doneAction:(UIBarButtonItem*)barButton   //doneAction     /*! cancelAction. */  -(void)cancelAction:(UIBarButtonItem*)barButton  //cancelAction   }

特征

1)支持设备方向。 
2)启用/禁用键盘消息时,需要设置 enable 的布尔值。 
3)简单的集成。 
4)作为一个textField/textViewAutoHandle UIToolbar需要设置 enableAutoToolbar 的布尔值。 
5)可以由父视图AutoHandle UIToolbartextField/textView,使用toolbarManageBehaviour枚举。
6)方便地添加上下和完成按钮键盘UIToolbar UIView类,自动使用enableAutoToolbar布尔值。 
7)启用/禁用,下/上一个按钮类的方法,自动使用enableAutoToolbar布尔值。 
8)键盘设置距离文本框使用keyboardDistanceFromTextField。 
9)键盘触摸外面用shouldResignOnTouchOutside. 禁用。 
10)管理的框架时,UITextView高度太大,使用canAdjustTextView 设置适合屏幕。
