去相冊選照片時，導(dǎo)航的背景色和頁面的背景色不一致，影響美觀，需修改。

修改方式：

#pragma mark----UINavigationControllerDelegate

- (void)navigationController:(UINavigationController*)navigationController willShowViewController:(UIViewController*)viewController animated:(BOOL)animated

{

//導(dǎo)航背景色

navigationController.navigationBar.barTintColor=Color_87BA4B;

//右側(cè)取消按鈕顏色

[navigationController.navigationBarsetTintColor:[UIColorwhiteColor]];

//標(biāo)題顏色

[navigationController.navigationBarsetTitleTextAttributes:@{

NSForegroundColorAttributeName: [UIColorwhiteColor],NSFontAttributeName:[UIFontsystemFontOfSize:18.0]

}];

}
