Question

我一直面临着在循环中以编程方式创建uitextfield并将它们全部置于可编辑模式的问题？

我在循环中成功创建了文本字段，但问题是这样。最后一个，即最后一个文本字段处于可编辑模式。

EX：假设一个数组（myarray）有5个值。

-(void)createDynamic_textfld{

    UITextField *roomratetxt;

    UIScrollView *scrlsummery;

    NSMutableArray *myarray = [NSMutableArray arrayWithObjects:@[@"one",@"two",@"three",@"four",@"five"], nil];

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

        roomratetxt = [[UITextField alloc]init];

        roomratetxt.frame = CGRectMake(200, 0, 90, 20);

        roomratetxt.textColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lighttextcolor.png"]];

        roomratetxt.backgroundColor = [UIColor clearColor];

        roomratetxt.font = [UIFont systemFontOfSize:12];

        roomratetxt.text = [NSString stringWithFormat:@"%@",[myarray objectAtIndex:i]];

        roomratetxt.textAlignment = NSTextAlignmentRight;

        [roomratetxt setTag:i];

        [roomratetxt setDelegate:(id)self];

        [scrlsummery addSubview:roomratetxt];

    }

}

我希望以可编辑模式制作所有5个文本字段。但截至目前，最后一个文本字段仅处于编辑模式，其余均为非可编辑模式。

任何人都可以向我提出一些想法吗？如何实现这一目标

首先，你需要提供不同的框架，你可以在不同的位置。您的上述代码看起来是正确的，并且必须处于可编辑模式。我在我的项目上执行下面的片段，它就像一个魅力。我假设您正在使用Scrollview并在其中添加了所有文本字段。唯一可以确保你没有从

中禁用它们

（BOOL）textFieldShouldBeginEditing：（UITextField *）textField; //返回NO以禁止编辑。

或

（BOOL）textField：（UITextField *）textField shouldChangeCharactersInRange：（NSRange）范围   replacementString：（NSString *）string; //返回NO不变化   文本

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

roomratetxt = [[UITextField alloc]init];

roomratetxt.frame = CGRectMake(200, i*20, 90, 20);

roomratetxt.textColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lighttextcolor.png"]];

roomratetxt.backgroundColor = [UIColor clearColor];

roomratetxt.font = [UIFont systemFontOfSize:12];

roomratetxt.text = [NSString stringWithFormat:@"%@",[myarray objectAtIndex:i]];

roomratetxt.textAlignment = NSTextAlignmentRight;

[roomratetxt setTag:i];

[roomratetxt setDelegate:(id)self];

[scrlsummery addSubview:roomratetxt];

}

-(void)createDynamic_textfld{

    UITextField *roomratetxt;

    UIScrollView *scrlsummery;

    NSMutableArray *myarray = [NSMutableArray arrayWithObjects:@[@"one",@"two",@"three",@"four",@"five"], nil];

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

        roomratetxt = [[UITextField alloc]init];

        roomratetxt.frame = CGRectMake(200, i*0, 90, 20);

        roomratetxt.textColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lighttextcolor.png"]];

        roomratetxt.backgroundColor = [UIColor clearColor];

        roomratetxt.font = [UIFont systemFontOfSize:12];

        roomratetxt.text = [NSString stringWithFormat:@"%@",[myarray objectAtIndex:i]];

        roomratetxt.textAlignment = NSTextAlignmentRight;

        [roomratetxt setTag:i];

        [roomratetxt setDelegate:(id)self];

        [scrlsummery addSubview:roomratetxt];

    }

}

Answer 3

所有5个textField的框架都放在相同的位置。您可能还需要更改其框架。

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

roomratetxt = [[UITextField alloc] init];

roomratetxt.frame = CGRectMake(200, i*60, 90, 20);

roomratetxt.textColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lighttextcolor.png"]];

roomratetxt.backgroundColor = [UIColor clearColor];

roomratetxt.font = [UIFont systemFontOfSize:12];

roomratetxt.text = [NSString stringWithFormat:@"%@",[myarray objectAtIndex:i]];

roomratetxt.textAlignment = NSTextAlignmentRight;

[roomratetxt setTag:i];

[roomratetxt setDelegate:(id)self];

[scrlsummery addSubview:roomratetxt];

}

如何在循环内创建动态文本字段并使其全部可编辑模式？
