问题描述
我在IB中创建了一个自定义uiview并为其设置了类。
I've created a custom uiview in IB and set the class for it.
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
@interface myView : UIControl {
IBOutlet UITextView *textView;
}
@end
#import "myView.h"
@implementation myView
- (void)commonInit
{
[textView setText:@"lajsdfklasdfjl"];
}
- (id)initWithCoder:(NSCoder *)aDecoder
{
if (self = [super initWithCoder:aDecoder])
{
[self commonInit];
}
return self;
}
-(id)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame])
{
[self commonInit];
}
return self;
}
@end
我把带有文字的文字视图在IB中的这个视图并将其链接到IBOutlet IUTextView * textView。
当我在我的UIViewController上拖动这个自定义视图时(从IB的库中的类选项卡),视图为空。
- (id)initWithCoder:(NSCoder *)aDecoder正在调用但textView为null。
有什么问题?谢谢
I put a textview with text on this view in IB and linked it to IBOutlet IUTextView *textView.When I drag this custom view on my UIViewController (from classes tab in IB's library) the view is empty. - (id)initWithCoder:(NSCoder *)aDecoder is calling but the textView is null. What is wrong? Thanks
推荐答案
据我记忆,在init中没有正确设置层次结构,因为属性只能在之后设置init已经完成。
As far as I remember, the hierarchy is not properly set up in init, as the properties can only be set after init has finished.
你想使用
-(void)awakeFromNib
{
[super awakeFromNib];
[self commonInit];
}
而是删除 initWithCoder:
完全没事。
作为旁注,你应该让你的班级名字以大写字母开头。
As a side note, you should let your class names begin with upper case letters.
