Cocoa:Testing for the same object with ifs/switches
Ok so here's my code, it works great:
- (void)textViewDidChange:(UITextView *)textView{
if (textView==someObject) {
[detailItem setValue:textView.text forKey:@"someObjectAttrib开发者_如何学Goute"];
}
The problem is that I have lots of textviews instances to test for and I would prefer to find some other way to consolidate the code. I was thinking of something like a switch but I don't see how that would work. Any ideas?
One way would be to use the integer tag of each view. In your code, you’d have an enum like:
enum
{
kThingView,
kOtherView,
...
};
Each view's tag is set appropriately in IB or when setting up the view programatically. Then:
- (void) textViewDidChange:(UITextView *)textView
{
switch (textView.tag)
{
case kThingView:
...
}
}
