UITextfield 和 UIButton 没有在 UIView 内点击

Question

我在 UIView 中有一些文本字段和按钮，但点击事件没有被调用我检查了 UIView 的高度，它比我的按钮和文本视图更多。正如你在 UIView 的截图中看到的： Frame of UIView 这些是 TextField 和按钮的屏幕截图 This is the first Label

And this is the last button

在两者之间有很多标签和文本字段。正如你在这张图片中看到的 This is the image of my view

我也设置了

userInteractionEnabled=NO 

对于 UIView 和

userInteractionEnabled=YES;

对于 TextField 和 Button 但仍然没有运气。我不知道下一步该做什么。这是我的代码

- (void)addChemicalTapped:(UIButton *)sender {

    _ans6Constraint.constant = 750;
//    [self.addChemical addTarget:self action:@selector(fixDelaysContentTouches:) forControlEvents:UIControlEventTouchUpInside];


   [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleTextBeginEditing:) name:UITextFieldTextDidBeginEditingNotification object:_Ans6Text1new1];

    _chemicalUIview.userInteractionEnabled=NO;
//    _chemical1scroll.userInteractionEnabled=false;
    _Ans6Text4new1.userInteractionEnabled=YES;
    _Ans6Text2new1.userInteractionEnabled=YES;
    _Ans6Text1new1.userInteractionEnabled=YES;
    _Ans6Text3new1.userInteractionEnabled=YES;
    [_RemoveChemical1 setTag:1234];
    [_RemoveChemical1 addTarget:self action:@selector(RemoveChemical1Tapped:) forControlEvents:UIControlEventTouchUpInside];
     [self reloadTable];
}

点击事件没有问题，因为相同文本字段和按钮的 id 在不同的 UIView 中被调用。所以我的 UIView 代码有问题。这是我的 UIView 代码

UIView *paddingView3 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
    [_ans6Text1 setClipsToBounds:NO];
    [_ans6Text1.layer setBorderWidth:1.0];
    [_ans6Text1.layer setBorderColor:[UIColor whiteColor].CGColor];
    [_ans6Text1.layer setCornerRadius:4.0];
    [_ans6Text1 setLeftView:paddingView3];
    [_ans6Text1 setLeftViewMode:UITextFieldViewModeAlways];
        UIView *paddingView3new1 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
        [_Ans6Text1new1 setClipsToBounds:NO];
        [_Ans6Text1new1.layer setBorderWidth:1.0];
        [_Ans6Text1new1.layer setBorderColor:[UIColor whiteColor].CGColor];
        [_Ans6Text1new1.layer setCornerRadius:4.0];
        [_Ans6Text1new1 setLeftView:paddingView3new1];
        [_Ans6Text1new1 setLeftViewMode:UITextFieldViewModeAlways];

    UIView *paddingView4 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
    [_ans6Text2 setClipsToBounds:NO];
    [_ans6Text2.layer setBorderWidth:1.0];
    [_ans6Text2.layer setBorderColor:[UIColor whiteColor].CGColor];
    [_ans6Text2.layer setCornerRadius:4.0];
    [_ans6Text2 setLeftView:paddingView4];
    [_ans6Text2 setLeftViewMode:UITextFieldViewModeAlways];
    [_ans6Text2 setInputView:_datePicker];
        UIView *paddingView4new1 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
        [_Ans6Text2new1 setClipsToBounds:NO];
        [_Ans6Text2new1.layer setBorderWidth:1.0];
        [_Ans6Text2new1.layer setBorderColor:[UIColor whiteColor].CGColor];
        [_Ans6Text2new1.layer setCornerRadius:4.0];
        [_Ans6Text2new1 setLeftView:paddingView4new1];
        [_Ans6Text2new1 setLeftViewMode:UITextFieldViewModeAlways];
        [_Ans6Text2new1 setInputView:_datePicker];

    UIView *paddingView5 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
    [_ans6Text3 setClipsToBounds:NO];
    [_ans6Text3.layer setBorderWidth:1.0];
    [_ans6Text3.layer setBorderColor:[UIColor whiteColor].CGColor];
    [_ans6Text3.layer setCornerRadius:4.0];
    [_ans6Text3 setLeftView:paddingView5];
    [_ans6Text3 setLeftViewMode:UITextFieldViewModeAlways];
        UIView *paddingView5new1 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
        [_Ans6Text3new1 setClipsToBounds:NO];
        [_Ans6Text3new1.layer setBorderWidth:1.0];
        [_Ans6Text3new1.layer setBorderColor:[UIColor whiteColor].CGColor];
        [_Ans6Text3new1.layer setCornerRadius:4.0];
        [_Ans6Text3new1 setLeftView:paddingView5new1];
        [_Ans6Text3new1 setLeftViewMode:UITextFieldViewModeAlways];

    UIView *paddingView6 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
    [_ans6Text4 setClipsToBounds:NO];
    [_ans6Text4.layer setBorderWidth:1.0];
    [_ans6Text4.layer setBorderColor:[UIColor whiteColor].CGColor];
    [_ans6Text4.layer setCornerRadius:4.0];
    [_ans6Text4 setLeftView:paddingView6];
    [_ans6Text4 setLeftViewMode:UITextFieldViewModeAlways];
        UIView *paddingView6new1 = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 10, 20)];
        [_Ans6Text4new1 setClipsToBounds:NO];
        [_Ans6Text4new1.layer setBorderWidth:1.0];
        [_Ans6Text4new1.layer setBorderColor:[UIColor whiteColor].CGColor];
        [_Ans6Text4new1.layer setCornerRadius:4.0];
        [_Ans6Text4new1 setLeftView:paddingView6new1];
        [_Ans6Text4new1 setLeftViewMode:UITextFieldViewModeAlways];

Ans6Text1new1、Ans6Text2new1、Ans6Text3new1 和 Ans6Text4new1 是未被选中的文本字段。 这是我们获取日期的第二个文本字段的代码。

-(void)textFieldDidEndEditing:(UITextField *)textField {
    NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
    [formatter setDateFormat:@"dd-MM-yyyy"];
    NSString *selectedDate = [formatter stringFromDate:[self.datePicker date]];
    NSString *pastDate = [formatter stringFromDate:[self.datePickerPast date]];

    if ([textField isEqual:_ans6Text2]) {
        [self.ans6Text2 setText:selectedDate];
        [self.ans6Text2 setBackgroundColor:[UIColor whiteColor]];
        [self.ans6Text2 setTextColor:[UIColor colorWithRed:5.0/255.0 green:85.0/255.0 blue:160.0/255.0 alpha:1.0]];
    }
    if ([textField isEqual:_Ans6Text2new1]) {
        [self.Ans6Text2new1 setText:selectedDate];
        [self.Ans6Text2new1 setBackgroundColor:[UIColor whiteColor]];
        [self.Ans6Text2new1 setTextColor:[UIColor colorWithRed:5.0/255.0 green:85.0/255.0 blue:160.0/255.0 alpha:1.0]];
    }

    else if ([textField isEqual:_ans4Text2]) {
        [self.ans4Text2 setText:pastDate];
        [self.ans4Text2 setBackgroundColor:[UIColor whiteColor]];
        [self.ans4Text2 setTextColor:[UIColor colorWithRed:5.0/255.0 green:85.0/255.0 blue:160.0/255.0 alpha:1.0]];
    }
    else if ([textField isEqual:_ans7Text2]) {
        [self.ans7Text2 setText:pastDate];
        [self.ans7Text2 setBackgroundColor:[UIColor whiteColor]];
        [self.ans7Text2 setTextColor:[UIColor colorWithRed:5.0/255.0 green:85.0/255.0 blue:160.0/255.0 alpha:1.0]];
    }
    else if ([textField isEqual:_ans7Text4]) {
        [self.ans7Text4 setText:pastDate];
        [self.ans7Text4 setBackgroundColor:[UIColor whiteColor]];
        [self.ans7Text4 setTextColor:[UIColor colorWithRed:5.0/255.0 green:85.0/255.0 blue:160.0/255.0 alpha:1.0]];
    }
    else if ([textField isEqual:_ans7Text5]) {
        [self.ans7Text5 setText:pastDate];
        [self.ans7Text5 setBackgroundColor:[UIColor whiteColor]];
        [self.ans7Text5 setTextColor:[UIColor colorWithRed:5.0/255.0 green:85.0/255.0 blue:160.0/255.0 alpha:1.0]];
    }
    else if ([textField isEqual:_ans8Text1]) {
        [self.ans8Text1 setText:pastDate];
        [self.ans8Text1 setBackgroundColor:[UIColor whiteColor]];
        [self.ans8Text1 setTextColor:[UIColor colorWithRed:5.0/255.0 green:85.0/255.0 blue:160.0/255.0 alpha:1.0]];
    }
}

Ans6Text2new1 是没有被点击的文本字段。我的布局截图如下 The UIView is marked in Red。有两个 UIView。在第一个 UIView 中，所有 TextField 和按钮都在工作，而在 First UIView 内的第二个 UIView 中，没有 Button 或 textfield 正在工作。这是我在 UIView 中单击按钮的代码，它也不起作用

- (void)add1ChemicalTapped:(UIButton *)sender {

   NSLog(@"ADDnew tapped");
}

在 viewDidLoad 中

- (void)viewDidLoad {
    @try{
    [super viewDidLoad];

    if(self.isReceived==true){
        [_HSSwitch setEnabled:NO];
    }


        [_Add1Chemical addTarget:self action:@selector(add1ChemicalTapped:) forControlEvents:UIControlEventTouchUpInside];
}

Answer 1

不用打电话

userInteractionEnabled=NO 

因为如果您为 Parent UIView 调用它，那么它也会禁用子视图的用户交互。
