UIBarButtonItem为状态设置颜色

Question

尝试为UIBarButtonItem设置颜色。问题是我对setTitleTextAttributes和UIControlStateDisabled两个UIControlStateNormal NSDictionaries NSDictionary *enabled = [NSDictionary dictionaryWithObjectsAndKeys: [UIColor purpleColor],NSForegroundColorAttributeName, [UIFont fontWithName:@"Playball" size:20], NSFontAttributeName, nil]; NSDictionary *disabled = [NSDictionary dictionaryWithObjectsAndKeys: [UIColor yellowColor],NSForegroundColorAttributeName, [UIFont fontWithName:@"Playball" size:20], NSFontAttributeName, nil]; [[self toolBarItem] setTitleTextAttributes:disabled forState:UIControlStateDisabled]; [[self toolBarItem] setTitleTextAttributes:enabled forState:UIControlStateNormal]; [[self toolBarItem] setEnabled:NO]; 不能toolBarItem。

这就是我要做的事情：

setEnable:NO

出于某种原因，{{1}}是紫色的，因为它应该是黄色的，因为{{1}}，因此被禁用。
