的UIImage查看復位/空

Question

大家好我正在開發iOS應用程序，允許用戶挑選使用UIImagePicker的圖像。現在我必須創建一個恢復沒有圖像內的UIIageView的動作。誰能幫助我的代碼？

-(IBAction)emptyImage{ 

//code to empty the UIImageView 

} 

Answer 1

-(IBAction)emptyImage{ 

    imageView.image=[UIImage imageNamed:@"noimage.png"]; (OR) 

    imgview.image= nil; (OR) 

    imgview.image= [UIImage imageNamed:@""]; 


} 

Answer 2

嘗試使用這個....

-(IBAction)emptyImage 
{ 
    imageView.image=nil 
} 

Answer 3

-(IBAction)emptyImage 
{ 

    NSArray *remoVeSunBVIew = [self.view subviews]; 
     for(UIView *viw in remoVeSunBVIew) 
     { 
      [viw removeFromSuperview]; 
     } 
} 

希望這將幫助你..
