1. 導航欄按鈕添加圖片使其保持原色

UIBarButtonItem *rightBarItem = [[UIBarButtonItem alloc] initWithTitle:nil style:UIBarButtonItemStylePlain target:self action:@selector(點擊方法)];

self.navigationItem.rightBarButtonItem = rightBarItem;

[self.navigationItem.rightBarButtonItem setImage:[[UIImage imageNamed:@"圖片"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]]; 圖像渲染模式總是顯示原創

2.設置Cell的背景圖片

cell.backgroundView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"圖片"]];

3.searchBar的取消顯示按鈕 ?簽訂代理

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar

{

[searchBar resignFirstResponder];

[searBar setShowsCancelButton:NOanimated:YES];

}

-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar

{

[searBar setShowsCancelButton:YESanimated:YES];

//修改UISearchBar右側的取消按鈕文字顏色及背景圖片

for(idsearchbuttonsin[[searchBar subviews][0] subviews])//只需在此處修改即可

if([searchbuttons isKindOfClass:[UIButton class]]) {

UIButton *cancelButton = (UIButton*)searchbuttons;

//修改文字顏色

[cancelButton setTitle:@"取消"forState:UIControlStateNormal];

[cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

[cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];

}

}
