給UILabel中的文字加刪除線

UIKIT_EXTERN NSString * const NSStrikethroughStyleAttributeName NS_AVAILABLE(10_0, 6_0);  // NSNumber containing integer, default 0: no strikethrough
//官方註釋,NSNumber,默認值是0,不顯示刪除線

增加刪除線的方法:

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(50, 150, 100, 50)];
    NSAttributedString *attString = [[NSAttributedString alloc] initWithString:@"刪除線" attributes:@{NSStrikethroughStyleAttributeName:@1}];
    label.attributedText = attString;
