Question

So i have the below method declaration and definition,

  -(UIImageView *)returnImageView:(UIImageView *)myImageView color:(UIColor *)imageViewColor x:(int)xParameter y:(int)yParamater width:(int)widthParameter height:(int)heightParameter
{  
CGRect cellFrame = CGRectMake(xParameter, yParamater, widthParameter, heightParameter);
style:UITableViewStyleGrouped];
myImageView = [myImageView initWithFrame:cellFrame];
myImageView.backgroundColor =imageViewColor;
myImageView.opaque = YES;
return myImageView;
}

This method will return an image view.

I am trying to call it as

UIImageView *myImageViews;
UIColor *tableColor = [UIColor blueColor] ;
[self.view addSubview:[returnImageView:myImageViews color:tableColor x:17 y:10 width:290 height:230]; 

which is giving a compiler error use of undeclared identifier returnImageView. What is causing the error ?

Thanks

Answer 1

First of all a square bracket is missing after the last line of code.

Second you have to call “self” to get the method!

[self.view addSubview:[self returnImageView:myImageViews color:tableColor x:17 y:10 width:290 height:230]];

Third, did you declare your returnImageView method in the class-relative .h file?

-(UIImageView *)returnImageView:(UIImageView *)myImageView color:(UIColor *)imageViewColor x:(int)xParameter y:(int)yParamater width:(int)widthParameter height:(int)heightParameter;
