UITextView: How to really disable editing?

问题

I am trying to disable editing on my UITextView. I have tried [aboutStable setUserInteractionEnabled: NO], but it causes the page to not be accessible.

Here is the current code.

- (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];
}

回答1:

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:

Objective-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

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)
}

回答2:

You can use the property editable

textView.editable = NO;

回答3:

Swift 2.0 Version

self.textView.editable = false

More details can be found in the apple UIKit Framework Reference.

Additional UITextView Attributes to consider:

text
attributedText
font
textColor
editable
allowsEditingTextAttributes
dataDetectorTypes
textAlignment
typingAttributes
linkTextAttributes
textContainerInset

回答4:

For Swift 3.0 and Swift 4.0:

textView.isEditable = false

回答5:

If you are using interface builder, you can just uncheck "Editable" in the Attributes Inspector.

回答6:

Swift 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.

回答7:

If you want to prevent all user interaction you need to do the 2 following things:

    self.commentText.isEditable = false
    self.commentText.isSelectable = false

回答8:

Wow, this one's certainly being done to death! Sorry to add another but I should mention you can remove any user uncertainty with:

commentTextView.isUserInteractionEnabled = false
