iPhone - 从nib文件加载UIView？ [英] iPhone - Load a UIView from a nib file?

问题描述

我正在子类化UIView尝试从nib文件加载我在界面构建器中删除的视图。
我在返回行上收到以下错误：

I am subclassing UIView trying to load the view i have dropped in interface builder from a nib file. I get the following error on the return line:

由于未捕获的异常'NSGenericException'而终止应用程序，原因：'此编码器要求更换从initWithCoder返回对象：'

- (id)initWithCoder:(NSCoder *)aDecoder
{
    [super initWithCoder:aDecoder];
    NSArray *objects = [[NSBundle mainBundle]
                        loadNibNamed:@"MyView" 
                        owner:nil 
                        options:nil];
    if (self = [objects objectAtIndex:0])
    {
    }
    return [self retain];
}

推荐答案

你做的事情很奇怪）

loadNibNamed：owner：options：将调用 initWithCoder：从xib实例化你的视图。但是你从 initWithCoder：调用 loadNibNamed：owner：options：。无限递归？

loadNibNamed:owner:options: will call initWithCoder: to instantiate your view from xib. But you are calling loadNibNamed:owner:options: from initWithCoder:. Infinite recursion?

要从xib加载视图，您可以执行下一步：

To load view from xib you can do the next:

@implementation MyView

+ (MyView*) myView
{
  NSArray* array = [[NSBundle mainBundle] loadNibNamed:@"MyView" owner:nil options:nil];
  return [array objectAtIndex:0]; // assume that MyView is the only object in the xib
}

@end
