取消在蓝色导航栏中的MFMessageComposeViewController上不可见

Question

In my application my navigation bar color is blue.

While opening MFMessageComposeViewController its cancel button color is also blue so user is not able to see cancel button.

Cancel button is performing action, i cam dismiss MFMessageComposeViewController by clicking it.

Is there any way i can change cancel button color other than blue?

chagning tintColor of navigationBar should work

messageController.navigationBar.tintColor = [UIColor whiteColor];

只需在application:didFinishLaunchingWithOptions:上执行此操作application:didFinishLaunchingWithOptions:或者在实例化控制器之前执行此操作

[[UINavigationBar appearance] setBarTintColor:[UIColor blackColor]];
