在本页面对self.navigationItem.title赋值不成功
应该在上一个页面进行赋值self.navigationItem.title=@"详情";//必须有值
[self.navigationController pushViewController:本页面 animated:YES];的时候就会成功赋值
在本页面
- (void)viewDidAppear:(BOOL)animated
{
self.navigationItem.title = self.series;
}
- (void)viewDidLoad {
[self dataCarType];
}
- (void)dataCarType{
self.series = @"发动机回复等级划分";
[self viewDidAppear:YES];
}
