在UIView中查找类型的所有控件 [英] Find all controls of a type in a UIView

问题描述

我正在寻找一种自动本地化按钮/文本字段等上的文本的方法，对于这种方法，我需要在UIView上查找所有（例如）UIButton。

我尝试了以下2个方法，但他们都没有像我想让他们工作的工作：

  for（UIView * subView in self.view.subviews）
 {
 NSLog（@object class：％@，[subView class]）; 
 
 if（[subView isMemberOfClass：[UIButton class]]）
 NSLog（@Button found！）; 
} 
  

这段代码的问题是RoundedRectButton不匹配UIButton

我也试过下面的：

 
 code> for（UIButton * button in self.view.subviews）
 {
 //做我的东西
} 
   
 
 
有没有办法实际上只是从一个视图获取所有UIButtons？或者我真的需要通过查看他们的选择器找到控件。
解决方案
第一种方法是正确的， isMemberOfClass函数 isKindOfClass ：
 
 
  isKindOfClass ：返回布尔值
，表示接收者是
是给定类的实例还是任何继承了该类中
的类的
实例。
 
 
 
I am looking for a way to automatically localize texts on buttons/textfields etc and for this method I need to find all (for example) UIButton's on a UIView.

I tried the following 2 methods, but they both do no work like I want them to work:
for (UIView* subView in self.view.subviews)
{
    NSLog(@"object class : %@", [subView class]);

    if ([subView isMemberOfClass:[UIButton class]])
        NSLog(@"Button found!");
}
The problem with this piece of code is that a RoundedRectButton does not match the UIButton class, while it really is just a UIButton.

I also tried the following:
for (UIButton* button in self.view.subviews)
{
// Do my stuff
}
But the stupid thing is, is that cocoa-touch actually just lists all subviews in that for-loop (also the UITextFields etc).

Is there a way to actually just get all UIButtons from a view? Or do I really need to find controls by looking at their selectors.
解决方案
the first method is correct, except you need to change isMemberOfClass function to isKindOfClass:

  
isKindOfClass: Returns a Boolean value
  that indicates whether the receiver is
  an instance of given class or an
  instance of any class that inherits
  from that class.
