iOS 鍵盤自適應（IQKeyboardManager）使用小結

IQKeyboardManager Github地址

常常在開發一個應用程序，咱們遇到了一個問題，iPhone的鍵盤上滑覆蓋的UITextField / UITextView。IQKeyboardManager能夠防止鍵盤滑動問題和覆蓋UITextField / UITextView無需你輸入任何代碼，不須要額外的設置要求。使用IQKeyboardManager你只須要添加源文件到你的項目。

主要特色

1）無代碼 
2）自動工做 
3）沒有更多的UIScrollView
4）沒有更多的子類 
5）沒有更多的手動工做 
6）沒有更多#imports

IQKeyboardManager 支持 CocoaPods

pod ‘IQKeyboardManager’

管理

UINavigationBar

若是你不使用storyboard或xib創造你的視圖。你須要重寫-（void）UIViewController loadview方法，須要設置一個UIScrollView實例self.view。

 



  

 

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

爲某一個ViewController禁用IQKeyboardManager

若是你想在某個 viewcontroller 禁用 IQKeyboardManager 你應該在 ViewDidAppear 中禁用IQKeyboardManager，而在ViewWillDisappear啓用它 
代碼：

       #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

鍵盤的回車鍵處理

1）建立一個實例變量實例化IQKeyboardReturnKeyHandler 在 ViewController 的 viewDidLoad 中

代碼：

	  @implementationViewController {IQKeyboardReturnKeyHandler *returnKeyHandler;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    returnKeyHandler = [[IQKeyboardReturnKeyHandler alloc] initWithViewController:self];
}

改變鍵盤上的返回鍵。

設置實例變量爲零的dealloc方法

-(void)dealloc {
    returnKeyHandler = nil;
}

UIToolbar(IQToolbar)

1）若是你不想添加一個特定的自動工具欄在鍵盤上方，應該添加一個類做爲它的工具欄

textField.inputAccessoryView = [[UIView alloc] init];

2）若是你須要本身控制上/下/完成按鈕，那麼應該使用UIView類的方法，建立你的文本框工具欄。

代碼：

-(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 }

功能和使用

UIKeyboard 處理

+(instancetype)sharedManager : Returns the default singleton instance.

@property BOOL enable : Use this to enable/disable managing distance between keyboard & textField/textView).

@property CGFloat keyboardDistanceFromTextField : Set Distance between keyboard & textField. Can't be less than zero. Defaultis10.@property BOOL preventShowingBottomBlankSpace : Prevent to show bottom blanck area when keyboard slide up the view.

IQToolbar處理

@property BOOL enableAutoToolbar : Enable autoToolbar behaviour. If It is set to NO. You have to manually create UIToolbar for keyboard. Defaultis YES.

@property IQAutoToolbarManageBehaviour toolbarManageBehaviour : Setting toolbar behaviour to IQAutoToolbarBySubviews to manage previous/next according to UITextField's hierarchy in it's SuperView. Set it to IQAutoToolbarByTag to manage previous/next according to UITextField's tag propertyin increasing order. Defaultis IQAutoToolbarBySubviews.

@property BOOL shouldToolbarUsesTextFieldTintColor : If YES, then uses textField's tintColor propertyfor IQToolbar, otherwise tintColor is black. Defaultis NO. 

@property BOOL shouldShowTextFieldPlaceholder : If YES, then it add the textField's placeholder text on IQToolbar. Defaultis YES. 

@property UIFont *placeholderFont : placeholder Font. Defaultis nil. Defaultis YES.

UITextView處理

@property BOOL canAdjustTextView : Giving permission to modify TextView's frame. Adjust textView's frame when it is too big in height. Defaultis NO.

@property BOOL shouldFixTextViewClip : Adjust textView's contentInset to fix fix for iOS 7.0.x -(#Stackoverflow). Defaultis YES.

UIKeyboard 外觀覆蓋

@property BOOL overrideKeyboardAppearance : Override the keyboardAppearance for all textField/textView. Defaultis NO.

@property UIKeyboardAppearance keyboardAppearance : If overrideKeyboardAppearance is YES, then all the textField keyboardAppearance issetusing this property.

關閉UITextField/UITextView

@propertyBOOL shouldResignOnTouchOutside : Resign textField if touched outside of UITextField/UITextView.

-(void)resignFirstResponder : Resigns currently first responder field.

UISound處理

@property BOOL shouldPlayInputClicks : If YES, then it plays inputClick sound onnext/previous/done click. Defaultis NO.

UIAnimation

@property BOOL shouldAdoptDefaultKeyboardAnimation : If YES, thenuses keyboard default animation curve style to move view, otherwise uses UIViewAnimationOptionCurveEaseOut animation style. Defaultis YES.

特徵

1）支持設備方向。 
2）啓用/禁用鍵盤消息時，須要設置 enable 的布爾值。 
3）簡單的集成。 
4）做爲一個textField/textView的AutoHandle UIToolbar須要設置 enableAutoToolbar 的布爾值。 
5）能夠由父視圖AutoHandle UIToolbar或textField/textView，使用toolbarManageBehaviour枚舉。 
6）方便地添加上下和完成按鈕鍵盤UIToolbar UIView類，自動使用enableAutoToolbar布爾值。 
7）啓用/禁用，下/上一個按鈕類的方法，自動使用enableAutoToolbar布爾值。 
8）鍵盤設置距離文本框使用keyboardDistanceFromTextField。 
9）鍵盤觸摸外面用shouldResignOnTouchOutside. 禁用。 
10）管理的框架時，UITextView高度太大，使用canAdjustTextView 設置適合屏幕。 
11）適用在UITableView/UIScrollView 中的UITextField/UITextView
12）能夠輸入聲音在點擊「下/上一頁/完成」時。
