添加“填充”到UITextView [英] Add "padding" to a UITextView
问题描述
正如标题所示我试图向UITextView添加类似填充的行为。在我的导航控制器中按下视图时会生成textview,并出现以下代码:
as the title says i am trying to add padding-like behavior to a UITextView. The textview is generated when the view is pushed inside my navigation controller and the following code occurs:
self.textView.layer.cornerRadius = 7;
//pretty stuff is pretty
NSString *description = appDelegate.productInDisplay.description;
[self.textView setText:description];
//pretty stuff has content now
CGRect frame = textView.frame;
frame.size.height = textView.contentSize.height;
textView.frame = frame;
//set the UITextView to the size of it's containing text.
self.textView.editable = NO;
self.theScrollView.contentSize = CGSizeMake(320, 250 + textView.frame.size.height);
//set the parent scrollView's height to fit some other elements with fixed size (250)
//and the pre-mentioned UITextView
所以,一切正常,没关系,但是我想在UITextView的所有4个方面添加一些填充,我已经无法用3小时的谷歌搜索来做到这一点对于看似相当容易的事情。有什么建议吗?
so, it all works and it's ok, but i want to add some padding on all 4 sides of the UITextView and i've been unable to do this with 3 hours of googling for something that seems rather easy. Any suggestions?
推荐答案
编辑2015年1月16日:这是2012年写的,不再准确。如上所述使用-textContainerInset。
原帖:
使用contentInset实际上不起作用。您有两个合理的选择:子类UITextField并覆盖textRectForBounds:和editingRectForBounds:方法或在UIView上透明地创建文本字段并设置UIView的样式。
Using contentInset won't actually work. You have two reasonable choices: subclass UITextField and override the textRectForBounds: and editingRectForBounds: methods or create your text field transparently over a UIView and style the UIView.
子类化的示例UITextField:
Example of subclassing the UITextField:
- (CGRect)textRectForBounds:(CGRect)bounds {
return CGRectInset(bounds, 5, 5);
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
return CGRectInset(bounds, 5, 5);
}
将其包装在UIView中的示例:
Example of wrapping it in a UIView:
UIView *wrapView = [[UIView alloc] initWithFrame: CGRectMake(10, 10, 200, 30)];
[wrapView addSubview:textView];
wrapView.layer.borderColor = [UIColor darkGrayColor].CGColor;
wrapView.layer.borderWidth = 2.0;
wrapView.layer.cornerRadius = 5.0;
