Get all inside NSDictionary into a UITextView - ios

Question

I got a NSDictionary and I want to print it into a UITextView.
I tried using this code, but when I try to get it into a UITextView it gets only one line of text, when I NSLog it it works perfectly.
for(int i=0; i<[array count];i++) {
dictionary = [array objectAtIndex:i];
//that shows only one line from the dictionary in the textview
textview.text = [dictionary objectForKey:#"text"];
//that shows all the dictionary with key "text" in the log
NSLog(#"%#", [dictionary objectForKey:#"text"]);
}
is there a way to solve this problem?

Answer 1

you should append it to the existing text
textview.text = #"";
for(int i=0; i<[array count];i++)
{
dictionary= [array objectAtIndex:i];
//that shows only one line from the dictionary in the textview
textview.text = [textview.text stringByAppendingFormat:#"%#\n",[diction objectForKey:#"text"]]];
//that shows all the dictionary with key "text" in the log
NSLog(#"%#",[diction objectForKey:#"text"]);
}

Answer 2

The problem is that textview.text is overwriting the previous contents of textview.text.
What you need to do is append the string to the existing value of textview:
textview.text = [textview.text stringByAppendingString:[diction objectForKey:#"text"]];
But this will get all the values side by side, so you may want to add a space in between the values:
NSString *appendedText = [NSString stringWithFormat:#"%# %#", textview.text, [diction objectForKey:#"text"]];
textview.text = appendedText;
Finally, you can use modern Objective-C literals to access your dictionary objects like array[i] and diction[#"text"] instead of using objectAtIndex and objectForKey to type a little less.
