如何自定义UISearchBar的外观

Question

我想自定义搜索栏,我的意思是白盒子.我可以做吗？有关于此的一些文件吗？有没有办法隐藏白框,但不是字母.我可以至少让盒子变小吗？我的意思是减少身高

Answer 1

通过IOS 5.0你有机会使用

  [[UISearchBar appearance] setSearchFieldBackgroundImage:[UIImage imageNamed:@"searchbar.png"]forState:UIControlStateNormal];

Answer 2

这是我正在寻找的解决方案:子类化UISearchBar,并覆盖方法layoutSubviews

- (void)layoutSubviews {
   UITextField *searchField;
   NSUInteger numViews = [self.subviews count];
   for(int i = 0; i < numViews; i++) {
      if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?
        searchField = [self.subviews objectAtIndex:i];
      }
   }
   if(!(searchField == nil)) {
       searchField.textColor = [UIColor whiteColor];
       [searchField setBackground: [UIImage imageNamed:@"buscador.png"] ];
       [searchField setBorderStyle:UITextBorderStyleNone];
   }

   [super layoutSubviews];
}

                                forSearchBarIcon:UISearchBarIconSearch
                                           state:UIControlStateNormal];

// set Search Bar textfield background image
 [[UISearchBar appearance] setSearchFieldBackgroundImage:[UIImage imageNamed:@"search_box.png"]
                                                forState:UIControlStateNormal];

// set Search Bar texfield corder radius
UITextField *txfSearchField = [self.searchDisplayController.searchBar valueForKey:@"_searchField"];
txfSearchField.layer.cornerRadius = 10.8f;
