设置代表时崩溃 [英] Crash on Setting Delegate

问题描述

我有一个带有笔尖和协议的自定义视图（settingview）。我想将此视图添加到具有委托的viewcontoller上。当我设置其委托时，我的应用程序崩溃了，我不知道自己做错了什么。

I have a custom view (settingview) with nib and protocol. i want to add this view on a viewcontoller with delegate. When i set its delegate my app crashes and i don't know what i have done wrong.

我没有用于ViewController的NIB。

i don't have NIB for ViewController.

我要附加几张我的代码和View的NIB图片。

i am attaching few images of my code and View's NIB.

.h

@protocol  SettingViewDelegate

@required

-(void)CornerSlider:(id)sender;
-(void)MarginSlider:(id)sender;
-(void)BorderSlider:(id)sender;
-(void)ShadowSlider:(id)sender;
-(void)BorderColor:(id)sender;
-(void)ShadowColor:(id)sender;
-(void)remove:(id)sender;
@end

@interface SettingView : UIView

@property (nonatomic, assign) id  delegate;

-(IBAction)CornerSlider1:(id)sender;
-(IBAction)MarginSlider1:(id)sender;
-(IBAction)BorderSlider1:(id)sender;
-(IBAction)ShadowSlider1:(id)sender;
-(IBAction)BorderColor1:(id)sender;
-(IBAction)ShadowColor1:(id)sender;
-(IBAction)remove1:(id)sender;

@end

.m

@implementation SettingView


- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        self = [[[NSBundle mainBundle] loadNibNamed: @"Setting"
                                          owner: self
                                        options: nil] objectAtIndex:0];
    }
    return self;
}

-(IBAction)CornerSlider1:(id)sender
{
    [self.delegate CornerSlider:sender];
}
-(IBAction)MarginSlider1:(id)sender
{
    [self.delegate MarginSlider:sender];
}
-(IBAction)BorderSlider1:(id)sender
{
    [self.delegate BorderSlider:sender];
}
-(IBAction)ShadowSlider1:(id)sender
{
    [self.delegate ShadowSlider:sender];
}
-(IBAction)BorderColor1:(id)sender{
    [self.delegate BorderColor:sender];
}
-(IBAction)ShadowColor1:(id)sender{
    [self.delegate ShadowColor:sender];
}
-(IBAction)remove1:(id)sender{
    [self.delegate remove:sender];
}


@end

应用在设置其委托后崩溃。

app crashes here after setting its delegate.

SettingView *settingView=[[SettingView alloc]init];
[settingView setDelegate:self];
[self.view addSubview:settingView];

推荐答案

发现了错误。那是在IB。
我正在将自定义类别（SettingView）设置为文件所有者的类别。现在，其视图的自定义类和文件的所有者是UIView的类。

Mistake found. It was in IB. I was setting Custom Class (SettingView) to File's Owner's Class. Now Its View's Custom Class and File's Owner is UIView's Class.

，现在可以正常使用了。 。

and now its working fine. .
