IQKeyboardManager 键盘遮挡textField

经常在开发一个应用程序,我们遇到了一个问题,iPhone的键盘上滑覆盖的UITextField / UITextView。IQKeyboardManager可以防止键盘滑动问题和覆盖UITextField / UITextView无需你输入任何代码,不需要额外的设置要求。使用IQKeyboardManager你只需要添加源文件到你的项目。

主要特点

1)无代码 2)自动工作 3)没有更多的UIScrollView 4)没有更多的子类 5)没有更多的手动工作 6)没有更多#imports

UINavigationBar

如果你不使用storyboard或xib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"

@implementation ExampleViewController { 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:

@implementation ViewController { 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]; 1 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 }

UIKeyboard 处理

+(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. Default is 10.

@property BOOL preventShowingBottomBlankSpace : Prevent to show bottom blanck area when keyboard slide up the view.

IQToolbar处理

@property BOOL enableAutoToolbar : Enable autoToolbar behaviour. If It is set to NO. You have to manually create UIToolbar for keyboard. Default is 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 property in increasing order. Default is IQAutoToolbarBySubviews.

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

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

@property UIFont *placeholderFont : placeholder Font. Default is nil. Default is YES.

UITextView处理

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

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

UIKeyboard 外观覆盖

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

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

关闭UITextField/UITextView

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

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

UISound处理

@property BOOL shouldPlayInputClicks : If YES, then it plays inputClick sound on next/previous/done click. Default is NO. 1 UIAnimation

@property BOOL shouldAdoptDefaultKeyboardAnimation : If YES, then uses keyboard default animation curve style to move view, otherwise uses UIViewAnimationOptionCurveEaseOut animation style. Default is YES. 1 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/textView的AutoHandle UIToolbar需要设置 enableAutoToolbar 的布尔值。 5)可以由父视图AutoHandle UIToolbar或textField/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。 11)适用在UITableView/UIScrollView 中的UITextField/UITextView 12)可以输入声音在点击“下/上一页/完成”时。
