UITextView里面的UIScrollView不是第一反应 [英] UITextView inside UIScrollView is not First Responder

问题描述

在Interface Builder中将UITextView嵌入UIScrollView内部时，UITextView不再是第一个响应者。响应者。我不知道发生了什么变化？

我想让UITextView成为第一个响应者。 b $ b

   - （void）viewDidLoad {
 [super viewDidLoad]; 
 [scrollView setContentSize：CGSizeMake（540,620）]; 
 composeTextView.delegate = self; 
 [composeTextView becomeFirstResponder]; 
} 
  

解决方案

这是我的.h文件：

  #import< UIKit / UIKit.h> 
 
 @interface Untitled1ViewController：UIViewController< UITextFieldDelegate> {
 UIScrollView * scrollView; 
 UITextField * composeTextView; 
} 
 
 @property（nonatomic，retain）IBOutlet UIScrollView * scrollView; 
 @property（nonatomic，retain）IBOutlet UITextField * composeTextView; 
 
 @end 
  

这是我的.m文件：

  #importUntitled1ViewController.h
 
 @implementation Untitled1ViewController 
 @synthesize scrollView; 
 @synthesize composeTextView; 
  - （void）viewDidLoad {
 [super viewDidLoad]; 
 [scrollView setContentSize：CGSizeMake（540,620）]; 
 composeTextView.delegate = self; 
 [composeTextView becomeFirstResponder]; $ IB 
 
 $ b} 
  

如下：
textField to composeTextView
scrollView to scrollView
and the textField delegate to the file's owner。

再试一次建议。 / p>

I have a UITextView on a View that becomes the first responder.

When I embed the UITextView inside of a UIScrollView in Interface Builder the UITextView is no longer the first responder. I am not sure what has changed?

I would like the UITextView to become the first responder.

- (void)viewDidLoad {
    [super viewDidLoad];
    [scrollView setContentSize:CGSizeMake(540,620)];
    composeTextView.delegate = self;    
    [composeTextView becomeFirstResponder];
}

解决方案

This is my .h file:

#import <UIKit/UIKit.h>

@interface Untitled1ViewController : UIViewController <UITextFieldDelegate> {
    UIScrollView *scrollView;
    UITextField *composeTextView;
}

@property (nonatomic,retain) IBOutlet UIScrollView *scrollView;
@property (nonatomic,retain) IBOutlet UITextField *composeTextView;

@end

this is my .m file:

#import "Untitled1ViewController.h"

@implementation Untitled1ViewController
@synthesize scrollView;
@synthesize composeTextView;
- (void)viewDidLoad {
    [super viewDidLoad];
    [scrollView setContentSize:CGSizeMake(540,620)];
    composeTextView.delegate = self;    
    [composeTextView becomeFirstResponder];


}

in IB, i've connected the following: textField to composeTextView scrollView to scrollView and the textField delegate to the file's owner.

Try again and advise.
