如何为UITableView的节索引设置色调？

Question

有没有办法自定义UITableView的字母部分索引的灰色？

Answer 1

Since iOS 6.0 it's actually possible to customize the tint color for the section index. The relevant properties are: sectionIndexColor and sectionIndexTrackingBackgroundColor .

iOS 7 added sectionIndexBackgroundColor which specifies the background color for the section index while not being touched.

Answer 2

It's maybe a bit late but as I had to deal with this problem with iOS 7 I might help you.

From iOS 7 there is a new method called :

@property(nonatomic, retain) UIColor *sectionIndexColor

Now you can set the color to use for the background of the table view's section index while not being touched.

As a proper code to use with iOS 6 and 7 you could :

self.friendsTableView.sectionIndexTrackingBackgroundColor = [UIColor aColor]; // background color while the index view is being touched
if ([self.friendsTableView respondsToSelector:@selector(sectionIndexBackgroundColor)])
    self.friendsTableView.sectionIndexBackgroundColor = [UIColor aColor]; // background color while the index view is NOT touched at all

Answer 3

你应该使用UITableView的外观代理来设置这些：

[UITableView appearance].sectionIndexColor = [UIColor myTintColor];

Answer 4

简而言之：你可以更改fontsize和完整的backround（不是圆形的）更多是不可能的。
