为什么在initWIthCoder：（NSCoder *）aDecoder中调用时，我的UIView图层属性未设置？ [英] Why are my UIView layer properties not being set when called within initWIthCoder:(NSCoder *)aDecoder?

问题描述

我有一个自定义View类构建的子类UIView。

I have a custom View class built which subclasses UIView.

这个视图是通过ViewController中的nib文件加载的：

This view is loaded through a nib file in the ViewController via:

[[NSBundle main] loadNibNamed:@"MyCustomView" owner:self options:nil];

内部 MyCustomView.h （可正确连接到IB视图类）
我有一些子视图属性链接：

Inside MyCustomView.h (which correctly hooked up in IB as the Main Views class) I have some subview properties linked:

@interface MyCustomView : UIView <UITextFieldDelegate> {
....
@public

UIView *backgroundLayer; // a subview of the Main View inside the nib
....
}

@property (nonatomic, retain) IBOutlet UIView *backgroundLayer;

此插座在Interface Builder中正确连接。

This outlet is properly connected within Interface Builder.

在 MyCustomView.m 中，我有以下实现：

#import <quartzcore/QuartzCore.h>

@implementation MyCustomView

@synthesize backgroundLayer;

- (id)initWithCoder:(NSCoder *)aDecoder {
   self = [super initWithCoder:aDecoder];
   if (self) {
      ....
      self.backgroundLayer.layer.cornerRadius = 12.0f;
      self.backgroundLayer.layer.borderColor = [UIColor lightGrayColor].CGColor;
      self.backgroundLayer.layer.maskToBounds = YES;
      ....
   }

NONE 正在应用那些backgroundLayer.layer设置。当我在模拟器运行自定义视图出现完全如何出现在NIB没有任何这些MOD？我缺少什么？

NONE of those backgroundLayer.layer settings are being applied. When I run in simulator the custom view appears exactly how it appears in the NIB without any of those mods? What am I missing? Am I making the calls in the incorrect place?

推荐答案

这个问题的正确答案是使用方法：

The correct answer to this issue was to use the method :

 -(void)awakeFromNib {
    ......
 }
