通過 [searchBarsetShowsCancelButton:YES];設置之後默認是“cancel”，想改為中文的

在stackoverflow上參考了很多方法都沒用

這裡的關鍵是要獲取到 searchbar中得 cancelButton

通過打印 [searchbar subviews]

得到結果如下

(lldb) po [searchBar subviews]

<__NSArrayM 0xd6b0db0>(

+H; layer = >

)

也就是其只有一個subview，在stackoverflow上得到些其實

這個cancelbutton在更深一層

打印

[[[searchBar subviews] objectAtIndex:0] subviews]

得到結果：

(lldb) po [[[searchBar subviews] objectAtIndex:0] subviews]

<__NSArrayM 0xd6b0dd0>(

>,

>,

>

)

也就是這個UINavigationButton，對它進行設置

代碼如下

    searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, 240, 24)];
    //導航條的搜索條
    searchBar.delegate = self;
    [searchBar setShowsCancelButton:YES];
    [searchBar setTintColor:[UIColor blackColor]];
    [searchBar setBarTintColor:[UIColor clearColor]];
    [searchBar setPlaceholder:@"搜索劇集"];
    
    for(UIView *view in  [[[searchBar subviews] objectAtIndex:0] subviews]) {
    
        if([view isKindOfClass:[NSClassFromString(@"UINavigationButton") class]]) {
            UIButton * cancel =(UIButton *)view;
            [cancel setTitle:@"取消" forState:UIControlStateNormal];
            [cancel  setTintColor:[UIColor blackColor]];
            [cancel.titleLabel setTextColor:[UIColor blackColor]];
        }
    }
