LoginViewController *loginViewController =[[
LoginViewController alloc]
init];
UINavigationController *nav=[[UINavigationController
alloc]initWithRootViewController:loginViewController];
UIButton *leftBtn = [UIButton
buttonWithType:UIButtonTypeCustom];
leftBtn.frame =
CGRectMake(0,
0, 70,
37);
leftBtn.titleLabel.font=[UIFont
systemFontOfSize:25.0];
[leftBtn setTitle:@"取消"
forState:UIControlStateNormal];
[leftBtn addTarget:self
action:@selector(dismissController)
forControlEvents:UIControlEventTouchUpInside];
loginViewController.navigationItem.leftBarButtonItem =[[UIBarButtonItem
alloc] initWithCustomView:leftBtn];
[self.navigationController
presentViewController:nav
animated:YES
completion:nil];
更改箭头颜色：
self.navigationController.navigationBar.tintColor = [UIColor
whiteColor];
iOS 页面跳转后更改左边导航栏的文字还有箭头颜色
