无法更改iOS 7搜索栏中的文本颜色

Question

我需要更改UISearchBar文本字段中的文字颜色。我在这篇文章中尝试了两个答案：

UISearchBar text color change in iOS 7

但文字保持默认的灰色。我在viewDidLoad方法中设置了该代码。我能错过什么？有人有同样的问题吗？

Answer 1

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setTextColor:[UIColor blueColor]];

//This is done in Xcode 5.0 and its working btw i don't know whether it works with previous versions of Xcode or not....
// Also I wrote this method in viewDidLoad

Answer 2

// Get the instance of the UITextField of the search bar
UITextField *searchField = [self.searchBar valueForKey:@"_searchField"];

// Change search bar text color
searchField.textColor = [UIColor blueColor];
