UITextView: How to really disable editing?
提问by Otium
I am trying to disable editing on my UITextView. I have tried [aboutStable setUserInteractionEnabled: NO], but it causes the page to not be accessible.
我正在尝试禁用对我的UITextView. 我试过了[aboutStable setUserInteractionEnabled: NO]，但它导致页面无法访问。
Here is the current code.
这是当前的代码。
- (void)loadTextView1 {
UITextView *textView1 = [[UITextView alloc] init];
[textView1 setFont:[UIFont fontWithName:@"Helvetica" size:14]];
[textView1 setText:@"Example of editable UITextView"];
[textView1 setTextColor:[UIColor blackColor]];
[textView1 setBackgroundColor:[UIColor clearColor]];
[textView1 setTextAlignment:UITextAlignmentLeft];
[textView1 setFrame:CGRectMake(15, 29, 290, 288)];
[self addSubview:textView1];
[textView1 release];
}

First of all, you are using setter methods when you could just be using properties. Secondly, you are setting a whole bunch of unnecessary properties that are very close to the default. Here is a much simpler and perhaps what you intended with your code:
首先，当您可以只使用属性时，您正在使用 setter 方法。其次，您正在设置一大堆非常接近默认值的不必要属性。这是一个更简单的代码，也许是您想要的代码：
Objective-C
目标-C
- (void)loadTextView1 {
UITextView *textView1 = [[UITextView alloc] initWithFrame:CGRectMake(15, 29, 290, 288)];
textView1.text = @"Example of non-editable UITextView";
textView1.backgroundColor = [UIColor clearColor];
textView1.editable = NO;
[self addSubView:textView1];
[textView1 release];
}
Swift
迅速
func loadTextView1() {
let textView1 = UITextView(frame: CGRect(x: 15, y: 29, width: 290, height: 288))
textView1.text = "Example of non-editable UITextView"
textView1.backgroundColor = .clear
textView1.isEditable = false
addSubView(textView1)
}

You can use the property editable
您可以使用该物业 editable
textView.editable = NO;

Swift 3.0
斯威夫特 3.0
func loadTextView1()
{
let textView1 = UITextView()
textView1.text = "Example of non-editable UITextView"
textView1.backgroundColor = UIColor.clear
textView1.frame = CGRect(x: 15, y: 29, width: 290, height: 288)
textView1.isEditable = false
addSubView(textView1)
}
Otherwise in Xcode's Interface Builder uncheck "Editable" in the Attributes Inspector for the text view.
否则，在 Xcode 的 Interface Builder 中，在文本视图的 Attributes Inspector 中取消选中“Editable”。
回答by Tad
If you are using interface builder, you can just uncheck "Editable" in the Attributes Inspector.
如果您使用的是界面构建器，您可以在属性检查器中取消选中“可编辑”。

If you want to prevent all user interaction you need to do the 2 following things:
如果你想阻止所有用户交互，你需要做以下两件事：
self.commentText.isEditable = false
self.commentText.isSelectable = false

Wow, this one's certainly being done to death! Sorry to add another but I should mention you can remove any user uncertainty with:
哇，这个肯定是被干死了！很抱歉添加另一个，但我应该提到您可以通过以下方式消除任何用户不确定性：
commentTextView.isUserInteractionEnabled = false
