iOS Label.text or TextView.text access NSSting

[andyiapan]

if i have NSString *a;
a[0] = @"hello,";
a[1] = @"i am peter,";
a[2] = @"how are you?";

how can i display all text in Label.text?

Label.text = a[0] + a[1] + a[2];

Output:
hello,i am peter,how are you?
in Label

I think you are confused. NSString *a should be pointing at a single NSString object. Not at an array of NSStrings.

if i declare NSString *a[10];
can i do that?

 

[robbieduncan]

If you really want to. I would suggest you look at the NSString documentation for appending them: + won't work.

Thx yr suggestion, i want to use a for loop, but still can't find the solution🙁

for(int i = 0; i < 3; i++)
XX = XX + a;
label1.text = XX

You cannot combine NSString objects with the + operator. This is not Java with dodgy special-case overrides for one type of object. Open the NSString documentation and search for append methods...

You will want to look at the string appendwithformat methods that is contained in the NSString class.
