ios7 關於searchbar上設定cancelButton的title屬性

標籤：ios7   searchbar   

  通過 [searchBarsetShowsCancelButton:YES];設定之後預設是“cancel”，想改為中文的

在stackoverflow上參考了很多方法都沒用

這裡的關鍵是要擷取到 searchbar中得 cancelButton

通過列印 [searchbar subviews]

得到結果如下

(lldb) po [searchBar subviews]

<__NSArrayM 0xd6b0db0>(

<UIView: 0xd6aab30; frame = (0 0; 240 24); clipsToBounds = YES; autoresize = 

+H; layer = <CALayer: 0xd6aab90>>

)

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

列印 

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

得到結果：

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

<__NSArrayM 0xd6b0dd0>(

<UISearchBarBackground: 0xd6ab370; frame = (0 0; 240 24); opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0xd6ab4c0>>,

<UINavigationButton: 0xd6abef0; frame = (0 0; 54 30); opaque = NO; layer = <CALayer: 0xd6ac020>>,

<UISearchBarTextField: 0xd6acbe0; frame = (0 0; 0 0); text = ‘‘; clipsToBounds = YES; opaque = NO; layer = <CALayer: 0xd6acdf0>>

)

也就是這個UINavigationButton，對它進行設定

代碼如下

    searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, 240, 24)];    //導航條的搜尋條    searchBar.delegate = self;    [searchBar setShowsCancelButton:YES];    [searchBar setTintColor:[UIColor blackColor]];    [searchBar setBarTintColor:[UIColor clearColor]];    [searchBar setPlaceholder:@"搜尋集"];        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]];        }    }
