UITextView 中间显示点击事件，不显示全选 复制 粘贴

1.效果图

效果图

找了好多都没起作用，在这里记录下，也帮助 和我有同样需求的同学。

2.代码示例

< QKNoCopyTextView.h >

#import <UIKit/UIKit.h>

@interface QKNoCopyTextView : UITextView

@end

不显示 放大镜，全选，复制 粘贴。代码 < QKNoCopyTextView.m >

#import "QKNoCopyTextView.h"

@implementation QKNoCopyTextView

-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{
    if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]] || [gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
        return [super gestureRecognizerShouldBegin:gestureRecognizer];
    }
    
    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) {
        UILongPressGestureRecognizer *longGesture =(UILongPressGestureRecognizer *) gestureRecognizer;
        if( longGesture.minimumPressDuration < 0.35){
            return [super gestureRecognizerShouldBegin:gestureRecognizer];
        }else{
            longGesture.enabled = false;
        }
    }
    
    return false;
}
@end

3.使用

A.viewcontroller 设置

self.numTipTextView.editable = NO;
self.numTipTextView.delegate = self;
[self configNumTipTextViewWithMessage:@"亲，您当天快捷免密登录剩余0次，请点击忘记密码重置登录密码"];

B.设置UI

-(void)configNumTipTextViewWithMessage:(NSString *)messageStr{
    if ([messageStr length] < 1) {
        messageStr = @"";
    }
    // 设置属性
    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
    // 设置行间距
    paragraphStyle.paragraphSpacing = 1; // 段落间距
    paragraphStyle.lineSpacing = 1;      // 行间距
    NSDictionary *attributes = @{
                                 NSForegroundColorAttributeName:[UIColor redColor],
                                 NSParagraphStyleAttributeName:paragraphStyle
                                 };
    NSMutableAttributedString * attrStr = [[NSMutableAttributedString alloc] initWithString:messageStr attributes:attributes];
    [attrStr addAttributes:@{
                             NSLinkAttributeName:@"忘记密码"
                             }
                     range:[messageStr rangeOfString:@"忘记密码"]];
    self.numTipTextView.linkTextAttributes = @{NSForegroundColorAttributeName:[UIColor blueColor]}; // 修改可点击文字的颜色
    self.numTipTextView.attributedText = attrStr;
}

delegate 实现

-(BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    NSString *messageStr = self.numTipTextView.attributedText.string;
    NSRange range = [messageStr rangeOfString:@"忘记密码"];
    if (characterRange.location == range.location) {
        // 做你想做的事
        NSLog(@"忘记密码");
        QKFindPwdController *findPwdController = [[QKFindPwdController alloc] init];
        
        [self.viewController.navigationController pushViewController:findPwdController animated:true];
    }
    return YES;
}
