细节上面的更改变换

1. 导航栏按钮添加图片使其保持原色

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

self.navigationItem.rightBarButtonItem = rightBarItem;

[self.navigationItem.rightBarButtonItem setImage:[[UIImage imageNamed:@"图片"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]]; 图像渲染模式总是显示原创

2.设置Cell的背景图片

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

3.searchBar的取消显示按钮  签订代理

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar

{

[searchBar resignFirstResponder];

[searBar setShowsCancelButton:NOanimated:YES];

}

-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar

{

[searBar setShowsCancelButton:YESanimated:YES];

//修改UISearchBar右侧的取消按钮文字颜色及背景图片

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

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

UIButton *cancelButton = (UIButton*)searchbuttons;

//修改文字颜色

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

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

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

}

}
