I am a beginner and I'd like to print an array on a label by pressing a button.
I already know how to put a String in the label like this:
@IBAction func Start(sender: UIButton) {
label.text = "Insert Array"
But instead of "Insert Array" I want to insert my function, which creates an Array at the end. If I insert the Array, it says:
use of unresolved identifier 'array'
My code works perfectly in the playground.
try with this.
you test() function has NSArray return type
func test()-> NSArray{
//bla bla bla
let myArray:NSArray = ["data1","data2","data3"]
print(myArray)
return myArray;
}
then you can get your result
label.text = test().componentsJoinedByString(",")
func test() { bla bla bla print(myArray) } I can't use "myArray" because it is in that scope, right? sorry, i'd rather not upload my function :/ Ps: I am still trying to figure out how to format comments :Pwhenever you want to print a non-String variable as a String use \()
label.text = "\(ArrayFunc())"
if this is for troubleshooting purposes use
println(ArrayFunc())
//or
println("Array: \(ArrayFunc())")
try below code for(NSString *str in resultArray){
[resultLabel.text= [str stringByAppendingString:@","];
}
my function, which creates an Array at the end
