我已经尝试过这个步骤:

1. 打开Xcode 6打开首选项
2. 单击"位置"选项卡
3. 将命令行工具版本更改为Xcode 6.0
4. 卸载cocoapods
5. 一个.$ sudo gem uninstall cocoapods安装xcodeproj
6. 一个.$ sudo gem install
7. xcodeproj安装cocoapods
8. 一个.$ sudo gem install cocoapods
9. 运行pod --version以验证它是否有效

但是当我进行pod安装或pod --version时,我仍然会这样做:

我在表视图中看到了关于如何创建浮动按钮的iOS浮动按钮.这是我创建按钮的方式.问题是该按钮将与表视图一起滚动.

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button]; 

我该如何解决这个问题？

我建议你使用https://github.com/gizmoboy7/VCFloatingActionButton这个链接....希望它对你有用
