標籤:ted value setattr uilabel pattern orm 刪除 table mutable
1.添加刪劃線方法遇到的問題
-(void)lastLabelDeal:(NSString *)str1 string:(NSString *)str2 label:(UILabel *)label{
NSMutableAttributedString
*str = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@ %@",str1,str2]];
[str addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlineStyleSingle|NSUnderlinePatternSolid) range:NSMakeRange(2, str1.length - 2)];
[str
addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(str1.length + 2,str2.length)];
//以下3行代碼是給label部分內容加刪劃線(這在iOS10.3之前一直這麼用,沒啥問題,可是10.3之後這樣子實現就毫無效果了)
[str addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlinePatternSolid|NSUnderlineStyleSingle) range:NSMakeRange(2, str1.length - 2)];
[str addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:12] range:NSMakeRange(2, str1.length - 2)];
[str addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(2, str1.length - 2)];
label.attributedText
= str;
}
2.最終解決辦法(上面3行代碼合并在一起最終實現了效果)
-(void)lastLabelDeal:(NSString *)str1 string:(NSString *)str2 label:(UILabel *)label{
NSMutableAttributedString
*str = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@ %@",str1,str2]];
[str addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlineStyleSingle|NSUnderlinePatternSolid) range:NSMakeRange(2, str1.length - 2)];
[str
addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(str1.length + 2,str2.length)];
//上面3行代碼合并在一起最終實現了效果
[str addAttributes:@{
NSStrikethroughStyleAttributeName:@(NSUnderlineStyleThick),
NSForegroundColorAttributeName:
[UIColor lightGrayColor],
NSBaselineOffsetAttributeName:
@(0),
NSFontAttributeName: [UIFont systemFontOfSize:12]
} range:NSMakeRange(2, str1.length - 2)];
label.attributedText
= str;
}
