ios – 同时在自定义UIView和UIViewController中使用相同的UITextFieldDelegate方法

概述我有一个带有子视图的UIView(名为HCTextFieldView)：上面的UITextField和UILabel. UITextField的委托等于self.委托方法textFieldDidBeginEditing和textFieldDidEndEditing执行textfield的背景突出显示效果. 接下来我在我的UIViewController中使用这个自定义UIView(HCTextFi @H_419_4@ 我有一个带有子视图的UIVIEw(名为HCTextFIEldVIEw)：上面的UITextFIEld和UILabel.

UITextFIEld的委托等于self.委托方法textFIEldDIDBeginEditing和textFIEldDIDEndEditing执行textfIEld的背景突出显示效果.

接下来我在我的UIVIEwController中使用这个自定义UIVIEw(HCTextFIEldVIEw).要处理工具栏中的“下一个”和“上一个”按钮的 *** 作(附在文本字段的键盘上方),我需要在UIVIEwController中使用相同的文本字段的委托方法,但是委托被覆盖了.

**@interface HCBaseTextFIEld : UIVIEw <UITextFIEldDelegate>**...@end**@implementation HCBaseTextFIEld {}**...textFIEld = [[UITextFIEld alloc] initWithFrame:CGRectMake(0,TitleLabel.bottom,self.wIDth - 20,self.height - TitleLabel.height)];**textFIEld.delegate = self**;...#pragma mark - UITextFIEld delegate//textFIEldBG - UIImageVIEw that act as background- (BOol)textFIEldShouldBeginEditing:(UITextFIEld *)textFIEld {    [textFIEldBg setimage:[[UIImage imageWithname:@"btn_vvod_medium_act"] stretchableImageWithleftCapWIDth:10 topCapHeight:10]];    return YES;}- (BOol)textFIEldShouldEndEditing:(UITextFIEld *)textFIEld {    [textFIEldBg setimage:[[UIImage imageWithname:@"btn_vvod_medium_norm"] stretchableImageWithleftCapWIDth:10 topCapHeight:10]];    return YES;}...@end**VIEwController : UIVIEwController**...HCTextFIEldVIEw *textFIEldVIEw = [[HCTExtFIEldVIEw alloc] init];textFIEldVIEw.textFIEld.delegate = self;...//I need to use this methods too but they overrIDe prevIoUs in UIVIEw delegate- (voID)textFIEldDIDBeginEditing:(UITextFIEld *)textFIEld{    [self.keyboardControls setActiveFIEld:textFIEld];}- (voID)textVIEwDIDBeginEditing:(UITextVIEw *)textVIEw{    [self.keyboardControls setActiveFIEld:textVIEw];}

@H_419_4@解决方法 在HCBaseTextFIEld中设置委托就像

在HCBaseTextFIEld.h中添加一个属性

@property (nonatomic,assign) ID<UITextFIEldDelegate> textFIEldDelagate;

在HCBaseTextFIEld.m中

- (BOol)textFIEldShouldBeginEditing:(UITextFIEld *)textFIEld {    ....    if (self.textFIEldDelagate && [self.textFIEldDelagate respondsToSelector:@selector(textFIEldShouldBeginEditing:)]) {        [self.textFIEldDelagate textFIEldShouldBeginEditing:textFIEld];    }    return YES;}- (voID) textFIEldDIDBeginEditing:(UITextFIEld *)textFIEld {    ....    if (self.textFIEldDelagate && [self.textFIEldDelagate respondsToSelector:@selector(textFIEldDIDBeginEditing:)]) {        [self.textFIEldDelagate textFIEldDIDBeginEditing:textFIEld];    }}... //Other delegate methods if needed

在VIEwController中：UIVIEwController

...HCTextFIEldVIEw *textFIEldVIEw = [[HCTExtFIEldVIEw alloc] init];textFIEldVIEw.textFIEldDelagate = self;...

并实现委托方法.

- (voID) textFIEldDIDBeginEditing:(UITextFIEld *)textFIEld {    ....    //Do the stuff}
