本地声明“x"隐藏实例变量 xcode 警告 [英] Local Declaration "x" hides instance variable xcode warning

问题描述

我一直无法理解这个问题.如果我更改变量名称 FifthViewController 错误消失但视图控制器不加载.

I've been have trouble understand this problem. If I change the variable name fifthViewController the error goes away but the view controller doesn't load.

迷路了.再一次，这可能很简单.

Lost. Once again it's probably something simple.

提前致谢.

代码如下:

{
FifthViewController *fifthViewController = [[FifthViewController alloc] initWithNibName:@"FifthView" bundle:nil];

fifthViewController.transactionID = transactionID;
[self.navigationController pushViewController:fifthViewController animated:NO]; 
[fifthViewController release];
 }

推荐答案

这意味着变量 fifthViewController 的名称与您的类实现中的其他名称相同.如果您打算使用该变量，请将 FifthViewController* 类型声明从第一行中删除；否则，请在该方法中出现的所有位置更改名称 fifthViewController.

This means the variable fifthViewController is named the same as something else in your class implementation. If you mean to use that variable, drop the FifthViewController* type declaration off the first line; otherwise, change the name fifthViewController everywhere it appears in that method.
