在哪里可以获得UISearchBar中使用的放大镜图标？ [英] Where can I get the magnifying glass icon used in UISearchBar?

问题描述

我使用 UITextField 作为 UISearchBar 替换和窃取放大镜图标从原始 UISearchBar 用这个疯狂的代码：

I'm using UITextField as a UISearchBar replacement and "stealing" the magnifying glass icon from the original UISearchBar with this crazy code:

    UISearchBar *originalSearchBar = [[UISearchBar alloc] init];
    for (UIView *searchBarSubview in [originalSearchBar subviews]) {
        if([searchBarSubview isKindOfClass:[UITextField class]]) {
            UITextField *textField = (UITextField *)searchBarSubview;
            [_textField setLeftView:[textField leftView]];
            [_textField setLeftViewMode:UITextFieldViewModeAlways];
        }
    }

正如你可能已经猜到的，我不想要使用我自己的位图。

As you've probably guessed, I don't want to use my own bitmap.

在Cocoa中有没有更容易访问的放大镜图标？

Isn't there an easier accessible magnifying glass icon somewhere in Cocoa?

推荐答案

所以，这里是unicode字符的代码：

So, here's the code with the unicode character:

    UILabel *magnifyingGlass = [[UILabel alloc] init];
    [magnifyingGlass setText:[[NSString alloc] initWithUTF8String:"\xF0\x9F\x94\x8D"]];
    [magnifyingGlass sizeToFit];

    [textField setLeftView:magnifyingGlass];
    [textField setLeftViewMode:UITextFieldViewModeAlways];

编辑：适合iOS 7风格的纯粹外观，选择器 \U000025B6 。

For plain look that fits iOS 7 style, add Unicode variation selector \U000025B6.
