Question

我有一个复选按钮和3个视图，一个TextField

我希望检查按钮能够知道它所在的视图，

view1 view1或view 3.这样当用户输入正确的答案时，特定的操作仅适用于该视图！

 - (IBAction)btncheck:(id)sender {



// Enter has been pressed, see if the text in the textView equals our string
NSString *answer = [_textbox.text stringByReplacingOccurrencesOfString:@"q telecom " withString:@""];
// to block user from getting incorrect answer with no text in text field
if([answer isEqualToString:@""]){

}
else

    if ([answer isEqualToString:@"q telecom"]) {


        //Name:Q Telecom - FIRST TEXTFIELD SAVED - This will save the answer (q telecom forever to the user) *SAVED
        NSString *savestring = _textbox.text; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        [defaults setObject:savestring forKey:@"savedstring"];
        [defaults synchronize];



    // String is correct, resign keyboard, xclear, and protection/shield
    _keyboard.hidden = YES;
    _textXclear.hidden = YES;
    _protectionOutBtn.enabled = NO;
    //Perfect button
    [_closeone setHidden:NO];
    [_wrongone setHidden:YES];

    score = MAX (score +100, 1);
    [scoreLabel setText:[NSString stringWithFormat:@"Σκορ: %d", score]];
   // remeber that coins must always be coins = coins + numeber to add up correctly
   coins = coins +5;
    if(score == 100) {coins = coins + 3;}




    [coinsLabel setText:[NSString stringWithFormat:@"%d", coins]];


    //coin animation start
    FImageWinfive.animationImages = [NSArray arrayWithObjects:[UIImage    imageNamed:@"coindust2.png"],[UIImage imageNamed:@"coindust3.png"],[UIImage imageNamed:@"coindust4.png"],[UIImage imageNamed:@"coindust5.png.png"],[UIImage imageNamed:@"coindust6.png"],[UIImage imageNamed:@"coindust7.png"],[UIImage imageNamed:@"coindust8.png"],[UIImage imageNamed:@"coindust9.png"],[UIImage imageNamed:@"coindust10.png"],[UIImage imageNamed:@"coindust11.png"],[UIImage imageNamed:@"coindust12.png"], nil];

    [FImageWinfive setAnimationRepeatCount:1];
    FImageWinfive.animationDuration = 1.5;
    FImageWinfive.animationRepeatCount = 1;
    [FImageWinfive startAnimating];
    //coin animation finished
    _textbox.enabled = NO;




}
else {


        CABasicAnimation *shake = [CABasicAnimation animationWithKeyPath:@"position"];
        [shake setDuration:0.1];
        [shake setRepeatCount:2];
        [shake setAutoreverses:YES];
        [shake setFromValue:[NSValue valueWithCGPoint:
                             CGPointMake(shaker.center.x - 5,shaker.center.y)]];
        [shake setToValue:[NSValue valueWithCGPoint:
                           CGPointMake(shaker.center.x + 5, shaker.center.y)]];
        [shaker.layer addAnimation:shake forKey:@"position"];


           // Was not correct.  Notify user, or just don't do anything


    [_wrongone setHidden:NO];
    score = score -3;





    [scoreLabel setText:[NSString stringWithFormat:@"Σκορ: %d", score]];

  //SCORE
}

if (score < 100) {
    closeonechange.text = @"Σωστά!";
     _imageCorP.image = [UIImage imageNamed:@"boxg_25.png"];

} else {
    closeonechange.text = @"Αψογα!";
    _imageCorP.image = [UIImage imageNamed:@"telioo.png"];
}

可能有一种更简单的方法，但这是一种选择。

首先，在viewController的{{1}}文件中，.m：

@property

现在，假设这个视图控制器委派了所有这三个文本字段：

@interface SomeViewController()
@property (nonatomic, weak) UITextField *activeField;
@end

现在在处理按钮触摸的方法中：

- (void)textFieldDidBeginEditing:(UITextField*)textField {
    self.activeField = textField;
}

稍微更好，更清晰的解决方案是使用- (IBAction)btncheck:(id)sender { if (self.lastActiveField == self.view1) { // check view 1 } else if (self.lastActiveField == self.view2) { // check view 2 } else if (self.lastActiveField == self.view3) { // check view 3 } else { // either no field has been selected yet or there are other text fields // delegated by this view controller } }并使用此enum设置文本字段的标记，然后在enum中，启用{ {1}}。

例如：

IBAction

跟踪上一个活动按钮的属性：

enum

现在，您可以在故事板或视图控制器的生命周期方法中设置它：

typedef NS_ENUM(NSInteger, ActiveFieldEnum) {
    tag_VIEW1 = 100,
    tag_VIEW2 = 101, 
    tag_VIEW3 = 102
};

文本字段委托：

@property (nonatomic,assign) ActiveFieldEnum lastActiveField;

现在按钮方法：

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    // set up your view

    self.view1.tag = tag_VIEW1;
    self.view2.tag = tag_VIEW2;
    self.view3.tag = tag_VIEW3;
}

如何制作一个按钮做两件事？
