如何爲UISearchBar着色，使其看起來與背景無縫

Question

我想着這個UISearchBar，使它看起來與背景無縫（如在第二個圖像中）。是否有可能做到這一點？我已經嘗試在IB和編程設置，但沒有運氣。

感謝您的幫助

這裏有所需的外觀：

Answer 1

UITextField *searchField = [self.searchBar valueForKey:@"_searchField"]; 
    [searchField setBackground:[UIImage imageNamed:@"searchfield_bg"]]; 

    [self.searchBar setTintColor:[UIColor blackColor]]; 
    UIImage *searchimg = [UIImage imageNamed:@"search_panel.png"]; 

    for (UIView *subview in self.searchBar.subviews) { 
     if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) { 
      UIView *bg = [[UIView alloc] initWithFrame:subview.frame]; 
      bg.backgroundColor = [UIColor colorWithPatternImage:searchimg]; 
      [self.searchBar insertSubview:bg aboveSubview:subview]; 
      [subview removeFromSuperview]; 
      [bg release]; 
      break; 
     } 
    } 

進出口使用這些圖片，你可以用你，改變顏色也一樣，我要求製作黑色搜索欄，以便使用黑色

，它會看起來像：

只是setTint顏色這樣的..

[searchBar setBarStyle:UIBarStyleDefault]; 
    [searchBar setTintColor:[UIColor colorWithRed:.81 green:.14 blue:.19 alpha:1]];//set alpha with your requirement 

也與圖像使用該代碼的工作很大..

for (UIView *subview in searchBar.subviews) { 
     if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) { 
      UIView *bg = [[UIView alloc] initWithFrame:subview.frame]; 
      bg.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"top-bar.png"]]; 
      [searchBar insertSubview:bg aboveSubview:subview]; 
      [subview removeFromSuperview]; 
      break; 
     } 
    } 

而對於w與紅色孔搜索欄，然後簡單的複製粘貼此代碼伴侶..在這裏我解決這個問題

for (UIView *subview in searchBar.subviews) { 
     if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) { 
      UIView *bg = [[UIView alloc] initWithFrame:subview.frame]; 
      bg.backgroundColor = [UIColor redColor]; 
      [searchBar insertSubview:bg aboveSubview:subview]; 
      [subview removeFromSuperview]; 
      break; 
     } 
    } 
    [searchBar setTintColor:[UIColor redColor]];
