Ios 如何使用带有标记的objective c从textfield访问文本值？

事实上，我对目标c还不熟悉。我的问题是如何从带有标记的textfield中获取文本。其中文本字段位于嵌套视图中。因此，我无法从嵌套视图中获取文本字段的值。如何使用objective c从stackview中提取文本

如图所示，我只从最后一个文本字段中获取文本，而不是从上面两个字段。我是动态创建的文本字段，如何获取每个文本字段的文本

else if ([key isEqualToString: textbox]){

            NSDictionary *widthAndHieght = [rowNames objectForKey:key];

            //NSLog(@"Hieght: %@",[widthAndHieght objectForKey:@"height"]);
            //NSLog(@"Width: %@",[widthAndHieght objectForKey:@"width"]);

            int height = [[widthAndHieght objectForKey:@"height"]intValue];
            int width = [[widthAndHieght objectForKey:@"width"]intValue];
            NSString *intTag = [[widthAndHieght objectForKey:@"tag"] objectForKey:@"tagInt"];

            myTextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, width, height)];
            myTextField.borderStyle = UITextBorderStyleRoundedRect;
            myTextField.font = [UIFont systemFontOfSize:15];
            //NSString *textFieldTag = [NSString stringWithFormat:@"%@", tagValue];
            //NSString *textFieldTag = myTextField.text;
            NSInteger b = [intTag integerValue];
            myTextField.tag = b;
            NSLog(@" Textfield tag:%ld",(long)myTextField.tag);
            myTextField.keyboardType = UIKeyboardTypeDefault;
            myTextField.returnKeyType = UIReturnKeyDone;
            myTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
            //[layout addSubview:myTextField];
            [layout addArrangedSubview:myTextField];


            NSNumber *tagNumber = [NSNumber numberWithInteger:b];
            [arrayOfTagValue addObject:tagNumber];
            NSLog(@" tag values :%@",arrayOfTagValue);

            NSDictionary *bindings3 = NSDictionaryOfVariableBindings(layout, myTextField);

            // Set the constraints for the label to be pinned equally with padding
            [greyView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-(30)-[myTextField]-(30)-|" options:NSLayoutFormatDirectionLeadingToTrailing metrics:nil views:bindings3]];
            [greyView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-(30)-[myTextField]-(30)-|" options:NSLayoutFormatDirectionLeadingToTrailing metrics:nil views:bindings3]];
        }

下面是我需要获取每个文本值但无法实现的代码。怎么做

-(void) sendBridge:(UITextField *)textField{

    for(int i = 0; i< [arrayOfTagValue count]; i++){

        NSLog(@"Value :%@",[arrayOfTagValue objectAtIndex:i]);

        if(textField == myTextField) {

            myTextField.textColor = [UIColor redColor];
            NSLog(@" text :%@",myTextField.text);
        }
    }

}

-（void）sendBridge:（UITextField*）textField{
对于（int i=0；i<[ArrayFTAGValue count]；i++）{
NSLog（@“值：%@，[ArrayFTAGValue对象索引：i]）；
如果（textField==myTextField）{
myTextField.textColor=[UIColor redColor]；
NSLog（@“text:%@”，myTextField.text）；
}
}
}

请使用以下命令：-

UITextField *txt = (UITextField*)[self.view viewWithTag:0]; 
NSString *strValue = txt.text;

以下是一个例子：

在viewcontroller.h中

@interface UIViewController : UIViewController<UITextFieldDelegate> {

 UITextField * listTitle;

}

希望它能有所帮助，您可以在

IBOutletCollection并这样引用它们。通过这种方式，您可以遍历包含文本字段的IBOutletCollection数组并获取值

这比标签安全得多，因为它不太容易发生用户错误

例如：

#import "ViewController.h"

@interface ViewController ()

@property (strong, nonatomic) IBOutletCollection(UITextField) NSArray *TextFieldsCollection;


@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    for (UITextField *textField in self.TextFieldsCollection) {
        NSLog(@"Placeholder: %@", textField.placeholder);
        NSLog(@"Text: %@", textField.text);
    }
}

@end

如果使用UIStackview，则可以执行以下操作：

不管怎样，回答得很好，乔治

但是我没有使用self.view，我使用的是堆栈视图。根据，我希望从嵌套的stackview中获取值。

#import "ViewController.h"

@interface ViewController ()

@property (strong, nonatomic) IBOutletCollection(UITextField) NSArray *TextFieldsCollection;


@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    for (UITextField *textField in self.TextFieldsCollection) {
        NSLog(@"Placeholder: %@", textField.placeholder);
        NSLog(@"Text: %@", textField.text);
    }
}

@end

 for (UITextField *txtField in [stackview subviews]) {

            if (txtField.tag == 1) {
                //...
            } else {
                //...
            }   
 }
