我有一个叫做 toolbarView 的子类,叫做 ToolbarView , 类似浮动窗口, 并且有一个有“ X” 按钮的 < code> UIToolbar , 可以使窗口消失。 我的问题是, 该对象能否从自己的类中删除自己?
例如,在 ToolbarView.m 中,我有一个方法 closeButtonPushed 当X按钮被按下时会点火。是否简单到要从它的 superview 中删除视图,然后调用 dealloc ?是否甚至有必要调用 dealloc ,因为一旦从 supperview 中删除,就不会有其他的指针。 或者这种错误的内存做法?
是的, 永远不要给交易者打电话。 如果超级视图是唯一能引用您视图的对象, 删除视图会使其保留数去到 0, 运行时间将会为您分配对象 。
您需要做的是在 close buttonPushed 方法中,调用
[self removeFromSuperView];
它将删除 ToolbarView 对象, IOS将调用 dealloc 方法和释放对象。 不需要手工调用 dealloc 。
