實現(xiàn)按鈕上面標題的換行、顏色區(qū)別、字體大小區(qū)別

//普通狀態(tài)

NSString *first = btnTitle;

NSString *second = [NSString stringWithFormat:@"贈送：%@元", detailTitle];

NSString *btnString = [NSString stringWithFormat:@"%@\n%@", first, second];

NSMutableAttributedString *btnAttriTitle = [[NSMutableAttributedString alloc] initWithString:btnString];

NSDictionary *dictNor = @{

NSForegroundColorAttributeName : BZChongZhiZengSongColor,

NSFontAttributeName : font1

};

NSRange rangeNor = NSMakeRange(first.length+1, second.length);

[btnAttriTitle? addAttributes:dictNor range:rangeNor];

button.titleLabel.numberOfLines = 0;

button.titleLabel.textAlignment = NSTextAlignmentCenter;

[button setAttributedTitle:btnAttriTitle forState:UIControlStateNormal];

//高亮、選中狀態(tài)

NSString *btnString2 = [NSString stringWithFormat:@"%@\n%@", first, second];

NSMutableAttributedString *btnAttriTitle2 = [[NSMutableAttributedString alloc] initWithString:btnString2];

NSDictionary *dictSel1 = @{

NSForegroundColorAttributeName : BZredColor,

NSFontAttributeName : font2

};

NSDictionary *dictSel2 = @{

NSForegroundColorAttributeName : BZredColor,

NSFontAttributeName : font1

};

NSRange rangeSel1 = NSMakeRange(0, first.length);

NSRange rangeSel2 = NSMakeRange(first.length + 1, second.length);

[btnAttriTitle2 addAttributes:dictSel1 range:rangeSel1];

[btnAttriTitle2 addAttributes:dictSel2 range:rangeSel2];

[button setAttributedTitle:btnAttriTitle2 forState:UIControlStateHighlighted];

[button setAttributedTitle:btnAttriTitle2 forState:UIControlStateSelected];

效果圖

-----常見問題---

button設置選中狀態(tài)后，再點擊沒有高亮狀態(tài)（起初設置高亮、選中狀態(tài)一樣）。

解決辦法：設置UIControlStateHighlighted | UIControlStateSelected狀態(tài)

```

[button setAttributedTitle:btnAttriTitle2 forState:UIControlStateHighlighted | UIControlStateSelected];

```
