ios7 关于searchbar上设置cancelButton的title属性

2024-07-11 17:54:05   221人阅读

  通过 [searchBarsetShowsCancelButton:YES];设置之后默认是“cancel”，想改为中文的

在stackoverflow上参考了很多方法都没用


这里的关键是要获取到 searchbar中得 cancelButton

通过打印 [searchbar subviews]

得到结果如下

(lldb) po [searchBar subviews]

<__NSArrayM 0xd6b0db0>(

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

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

)


也就是其只有一个subview，在stackoverflow上得到些其实

这个cancelbutton在更深一层

打印 

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


得到结果：

(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>>

)



也就是这个UINavigationButton，对它进行设置


代码如下

    searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, 240, 24)];
    //导航条的搜索条
    searchBar.delegate = self;
    [searchBar setShowsCancelButton:YES];
    [searchBar setTintColor:[UIColor blackColor]];
    [searchBar setBarTintColor:[UIColor clearColor]];
    [searchBar setPlaceholder:@"搜索剧集"];
    
    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]];
        }
    }
