UIButton *settingBtn = [SHUtils creatCustomButtonWithFrame:CGRectMake(0, 0, 60, 40) btnTitle:@"設置" btnFontSize:14 titleColor:[UIColor blackColor]]; [settingBtn addTarget:self action:@selector(clickTheSettingBtn) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *rightBar = [[UIBarButtonItem alloc]initWithCustomView:settingBtn]; UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; negativeSpacer.width = -20; self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:negativeSpacer,rightBar,nil];

效果為
