的UITextField不编辑正确

Question

我有3个UITextField S的给予如下动态：

if(a isEqualtoString:@"1") 
{ 

UITextField *t=[[UITextField alloc]initWithFrame:CGRectMake(20,20,20,20)]; 
t.text=s; 
t.delegale=self; 
[scroll addSubview:t]; 

} 
if(a isEqualtoString:@"2") 
{ 
UITextField *t=[[UITextField alloc]initWithFrame:CGRectMake(20,20,20,20)]; 
t.text=p; 
t.delegale=self; 
[scroll addSubview:t]; 


} 
if(a isEqualtoString:@"3") 
{ 
UITextField *t=[[UITextField alloc]initWithFrame:CGRectMake(20,20,20,20)]; 
t.text=r; 
t.delegale=self; 
[scroll addSubview:t]; 

} 

我的问题是，在这些文本框我写errT.hidden=YES;

这是我的代码的didBeginEditing但我无法编辑这些文本字段，并且我已经给予代理.h

也。该怎么办？我已经尝试了许多对我没有帮助的解决方案。帮我

UPDATE：

-(void)textFieldDidBeginEditing:(UITextField *)textField{ 
    if(textField==t) 
    { 
    err.hidden=YES; 
    } 
    } 

Answer 1

试试这个::

if(a isEqualtoString:@"1") 
{ 
    .... 
    t.text = @"s"; 
    .... 
} 
if(a isEqualtoString:@"2") 
{ 
    .... 
    t.text = @"p"; 
    .... 
} 
if(a isEqualtoString:@"3") 
{ 
    .... 
    t.text = @"r"; 
    .... 
} 

希望，它会帮助你。

我不明白如果你的问题是没有调用textFieldDidBeginEditing。

如果是，尝试这样做：如果“T”这是对.m文件创建，你必须用标签跟踪它

t.tag = 1001; 

-(void)textFieldDidBeginEditing:(UITextField *)textField{ 
    if(textField.tag == 1001) { 
     err.hidden=YES; 
    } 
} 

UPDATE： 尝试设置所有的财产和更改文本字段的名称（一定时间的作品）：

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(20,20,20,20)]; 
textField.borderStyle = UITextBorderStyleRoundedRect; 
textField.font = [UIFont systemFontOfSize:15]; 
textField.placeholder = @"enter text"; 
textField.autocorrectionType = UITextAutocorrectionTypeNo; 
textField.keyboardType = UIKeyboardTypeDefault; 
textField.returnKeyType = UIReturnKeyDone; 
textField.clearButtonMode = UITextFieldViewModeWhileEditing; 
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;  
textField.delegate = self; 
[self.scroll addSubview:textField]; 

你有没有尝试把文本框上的看法？ [self.view addSubview:textField];它行得通吗？文本框的

UITextField *t=[[[UITextField alloc]initWithFrame:CGRectMake(20,20,20,20)]autorelease]; 
t.delegale=self; 
[scroll addSubview:t]; 

if(a isEqualtoString:@"1") 
{ 
    t.text=s; 
} 
if(a isEqualtoString:@"2") 
{ 
    t.text=p; 
} 
if(a isEqualtoString:@"3") 
{ 
    t.text=r; 
} 

//代表

- (BOOL)textFieldShouldReturn:(UITextField *)textField 
{ 
    if ([textField canResignFirstResponder]) 
    { 
     [textField resignFirstResponder]; 
    } 
    return YES; 
} 
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField 
{ 
    // add your method here 
    return YES; 
} 
- (void)textFieldDidEndEditing:(UITextField *)textField 
{ 
}
