在項目中，我們狠容易遇到就是一些產(chǎn)品，他們什么也不懂，還就是喜歡瞎搞，比如說蘋果原生的UISegmentrol ,產(chǎn)品要求我們怎么怎么做，沒辦法，誰讓人家是產(chǎn)品呢，

于是我就只能看這個UISegmentrol的官方文檔了，看一遍不知道怎么修改，從頭到尾細致地看了兩遍，終于知道怎么弄了，

要的是這樣的一個效果，通過看官方的API，找到了答案，文檔上是這么說的：

/*

You may specify the font, text color, and shadow properties for the title in the text attributes dictionary, using the keys found in NSAttributedString.h.

*/

- (void)setTitleTextAttributes:(nullable NSDictionary *)attributes forState:(UIControlState)state NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;

- (nullable NSDictionary *)titleTextAttributesForState:(UIControlState)state NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;

看到上邊這幾句話，我頓時眼前一亮，馬上code就出來了，效果也就自然而然形成，code如下：

//修改系統(tǒng)的UISegmentControl

UIColor *textColor = PB_COLOR_18;//black

NSDictionary *textColorDic = [NSDictionary dictionaryWithObject:textColor forKey:NSForegroundColorAttributeName];

[segmentControl setTitleTextAttributes:textColorDic forState:UIControlStateNormal];

UIColor *selectTextColor = PB_COLOR_1;//blue

NSDictionary *selectTextColorDic = [NSDictionary dictionaryWithObject:selectTextColor forKey:NSForegroundColorAttributeName];

[segmentControl setTitleTextAttributes:selectTextColorDic forState:UIControlStateSelected];

OK。解決
