Question

我正在尝试将UISearchBar取消按钮的字体更改为＆＃39; OpenSans＆＃39;但我无法访问任何属性。我只能更改UISearchBar的色调颜色，它会改变搜索栏取消按钮文本和颜色的颜色。搜索栏UITextField游标颜色：

searchBar.tintColor = UIColor(red: 187.0/255.0, green: 187.0/255.0, blue: 187.0/255.0, alpha: 1.0)

有没有办法实现这个目标？

Answer 1

尝试这样的事情对我有用。

 UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).setTitleTextAttributes([NSFontAttributeName : UIFont(name: "OpenSans", size: 15)!], forState: .Normal)

如果您想更改颜色，请将其添加到您的属性数组中。

 NSForegroundColorAttributeName : UIColor.whiteColor()

注意：在iOS 9中提供

Answer 2

这适用于Swift 3.0

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes([NSFontAttributeName : UIFont(name: "OpenSans", size: 15)!], for: .normal)

Answer 3

swift 2：

if #available(iOS 9.0, *) {
     UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).setTitleTextAttributes([NSFontAttributeName : UIFont.systemFontOfSize(15, weight: UIFontWeightLight)], forState: .Normal)
} else {
     // Fallback on earlier versions
}

swift3：

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes([NSFontAttributeName : UIFont(name: "OpenSans", size: 15)!], for: .normal)

Objective-C：

[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                  [UIColor blueColor], 
                                                  UITextAttributeTextColor, 
                                                  [UIColor darkGrayColor], 
                                                  UITextAttributeTextShadowColor, 
                                                  [NSValue valueWithUIOffset:UIOffsetMake(0, -1)], 
                                                  UITextAttributeTextShadowOffset,
                                                  nil] 
                                        forState:UIControlStateNormal];
