[bright135]

eg: in LinkTextViewController.m , i will add addAttributeCharacterSpacing and addAttributeAlignmentStyle function
TYAttributedLabel *label1 = [[TYAttributedLabel alloc]initWithFrame:CGRectMake(0, 64, CGRectGetWidth(self.view.frame), 0)];
label1.delegate = self;
label1.highlightedLinkColor = [UIColor orangeColor];
[self.view addSubview:label1];
NSString *text = @"\t总有一天你将破蛹而出，成长得比人们期待的还要美丽。\n\t但这个过程会很痛，会很辛苦，有时候还会觉得灰心。\n\t面对着汹涌而来的现实，觉得自己渺小无力。\n\t但这，也是生命的一部分，做好现在你能做的，然后，一切都会好的。\n\t我们都将孤独地长大，不要害怕。";

NSArray *textArray = [text componentsSeparatedByString:@"\n\t"];
NSArray *colorArray = @[RGB(213, 0, 0, 1),RGB(0, 155, 0, 1),RGB(103, 0, 207, 1),RGB(209, 162, 74, 1),RGB(206, 39, 206, 1)];
NSInteger index = 0;

for (NSString *text in textArray) {

if (index == 2) {
    // 追加链接信息
    [label1 appendLinkWithText:text linkFont:[UIFont systemFontOfSize:15+arc4random()%4] linkData:@"http://www.baidu.com"];
}else {
    // 追加文本属性
    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]initWithString:text];
    [attributedString addAttributeTextColor:colorArray[index%5]];
    [attributedString addAttributeFont:[UIFont systemFontOfSize:15+arc4random()%4]];
    [label1 appendTextAttributedString:attributedString];
    [attributedString addAttributeCharacterSpacing:10];
    [[attributedString addAttributeAlignmentStyle:kCTTextAlignmentLeft lineSpaceStyle:40.0 paragraphSpaceStyle:40.0 lineBreakStyle:kCTLineBreakByWordWrapping];
}
[label1 appendText:@"\n\t"];
index++;

}

[label1 appendLinkWithText:@"百度一下" linkFont:[UIFont systemFontOfSize:15+arc4random()%4] linkData:@"http://www.baidu.com"];

[label1 sizeToFit];
_label1 = label1;
