iOS富文本Label实现点击事件，类似Word在横线上输入编辑

.h

NS_ASSUME_NONNULL_BEGIN

@interface GHAttributesLabel : UILabel

typedef void(^GHAttributesBlock)(NSRange poinRange)

/**

@param text 传入富文本类型的字符串

@param actionText 要响应事件的字符串

*/

/**

点击事件回调

*/

@property (nonatomic , copy) GHAttributesBlock actionBlock

@interface GHTextView : UITextView

@end

@implementation GHTextView

@end

@interface GHAttributesLabel()<UITextViewDelegate>

@property (nonatomic , strong) GHTextView *textView

@property (nonatomic , copy) NSString *actionText

/** <#注释#>*/

@property (nonatomic, assign) NSRange range

@end

@implementation GHAttributesLabel

//return YES

}

@end

使用

-(void)test{

GHAttributesLabel *attributesLabel = [[GHAttributesLabel alloc]initWithFrame:CGRectMake(10, 200, [UIScreen mainScreen].bounds.size.width - 20, 250)]

//NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:temp]

// NSRange range = [temp rangeOfString:actionStr]

//NSLog(@"range%@",NSStringFromRange(range))

NSArray *actionArr = [self rangeOfSubString:actionStr inString:temp]

NSLog(@"===:%@",[self rangeOfSubString:actionStr inString:temp])

for (int i = 0i <actionArr.counti++) {

NSValue *value = actionArr[i]

NSRange actionRange = [value rangeValue]

[attrStr addAttribute:NSLinkAttributeName

value:actionStr

range: actionRange]

}

}

}

return rangeArray

}

-(NSMutableAttributedString *)keyWords:(NSString *)keyWords withKeyWordsColor:(UIColor *)color

{

}

UILabel *l = [[UILabel alloc] initWithFrame:CGRectMake(60, 0, listV.frame.size.width - 60, listV.frame.size.height)]

l.userInteractionEnabled=YES

UITapGestureRecognizer *labelTapGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(labelTouchUpInside:)]

[l addGestureRecognizer:labelTapGestureRecognizer]

-(void) labelTouchUpInside:(UITapGestureRecognizer *)recognizer{

UILabel *label=(UILabel*)recognizer.view

NSLog(@"%@被点击了",label.text)

源码WPAttributedMarkup， WPAttributedMarkup能给Label中某关键字添加文字效果或点击事件。Label中的某个关键字词可以改变字体的特性如颜色、加粗，下划线等，也可以为某个关键字词添加点击事件。

使用方法：

通过创建不同的style的字典后就可以对label的属性进行设置，示例如下：

// Example using fonts and colours

NSDictionary* style1 = @{@"body":[UIFont fontWithName:@"HelveticaNeue" size:18.0],

@"bold":[UIFont fontWithName:@"HelveticaNeue-Bold" size:18.0],

@"red": [UIColor redColor]}

// Example using arrays of styles, dictionary attributes for underlining and image styles

NSDictionary* style2 = @{@"body" :

@[[UIFont fontWithName:@"HelveticaNeue-Bold" size:18.0],

[UIColor darkGrayColor]],

@"u": @[[UIColor blueColor],

@{NSUnderlineStyleAttributeName : @(kCTUnderlineStyleSingle|kCTUnderlinePatternSolid)}

],

@"thumb":[UIImage imageNamed:@"thumbIcon"] }

// Example using blocks for actions when text is tapped. Uses the 'link' attribute to style the links

NSDictionary* style3 = @{@"body":[UIFont fontWithName:@"HelveticaNeue" size:22.0],

@"help":[WPAttributedStyleAction styledActionWithAction:^{

NSLog(@"Help action")

}],

@"settings":[WPAttributedStyleAction styledActionWithAction:^{

NSLog(@"Settings action")

}],

@"link": [UIColor orangeColor]}

self.label1.attributedText = [@"AttributedBoldRedtext" attributedStringWithStyleBook:style1]

self.label2.attributedText = [@"[td]Multiplestylestext[td]" attributedStringWithStyleBook:style2]
