Android中TextView自动识别url且实现点击跳转
前言
在项目中要在展示展示的文字中,自动匹配url 并且点击实现跳转,看了很多第三方的感觉都很复杂。后来自己写了一个简单的。
实现代码如下
1、创建一个继承UITextView的CjTextView 。
import <UIKit/UIKit.h> @interface CjTextView : UITextView @end import "CjTextView.h" @interface CjTextView () @property (nonatomic, copy ) NSString myText; @property (nonatomic, assign) NSRange urlTange; @property (nonatomic, copy ) NSString url; @end @implementation CjTextView -(instancetype)initWithFrame:(CGRect)frame{ if (self = [super initWithFrame:frame]) { } return self; } // 重写了text的set 方法 -(void)setText:(NSString * )text{ self.myText = text; [self.textStorage setAttributedString:[[NSAttributedString alloc]initWithString:text]]; NSRange range = NSMakeRange(0, self.myText.length); [self.textStorage addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:20] range:range]; 在这个方法中可以改变网址的颜色字体大小等属性。 [self doing]; } -(void)layoutSubviews{ [super layoutSubviews]; self.textContainer.size = self.bounds.size; } -(void)touchesBegan:(NSSet<UITouch *> )touches withEvent:(UIEvent )event{ CGPoint point = [[touches anyObject] locationInView:self]; NSRange range =self.urlTange; self.selectedRange = range; NSArray array = [self selectionRectsForRange:self.selectedTextRange]; for (UITextSelectionRect obj in array) { if (CGRectContainsPoint(obj.rect, point)) { NSLog(@"你点击了网址%@",_url); } } } -(void) doing { NSDataDetector * dataDetector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingAllTypes error:nil]; NSArray res= [dataDetector matchesInString:self.textStorage.string options:NSMatchingReportProgress range:NSMakeRange(0, self.textStorage.string.length)]; for (NSTextCheckingResultresult in res) { self.urlTange = result.range; NSString str = [self.textStorage.string substringWithRange:result.range]; self.url = str; NSMutableAttributedString *att= [[NSMutableAttributedString alloc]initWithString:str]; [att addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0, str.length)]; [att addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:20] range:NSMakeRange(0, str.length)]; [self.textStorage replaceCharactersInRange:result.range withAttributedString:att]; } } @end
2、在控制器中实现
include "CjTextView.h" @interface ViewController () @end @implementation ViewController (void)viewDidLoad { [super viewDidLoad]; CjTextView *label = [[CjTextView alloc]init];
关掉弹出键盘
label.editable = NO; label.text = @"123发送的股份大概放到放到地方多福多寿http://baidu.comuiiyiroiqiotioq" ; label.backgroundColor = [UIColor yellowColor]; label.frame = CGRectMake(100, 100, 202, 200);; [self.view addSubview: label]; }
就是这么简单的代码就实现了
