想要在navigation controller 的顶端条添加一个刷新键。不知道为什么不执行。
hearder代码:
@interface PropertyViewController : UINavigationController {}
添加button代码:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Show" style:UIBarButtonItemStylePlain
target:self action:@selector(refreshPropertyList:)];
self.navigationItem.rightBarButtonItem = anotherButton; } return self; } 不知道错误在哪儿
