nsmutablearray help

[lll3mk4]

Hello I would like to make an NSmutableArray and add 3 text fields to the NSmutableArray so I dont need to repeat this code three times.

if ([textfield1.text length] >= 3) {

textfield1.text = [textfield1.text substringWithRange:NSMakeRange(0,2)];

But when ever I add the three text fields to the NSmutableArray it wont let me replace the "textfield1.text" with "NSmutableArray.text" why is this? Is there another way that might solve my problem!


Thanks

Use [NSMutableArray ObjectAtIndex:index]

Mutable arrays don't have a text property. NSMutableArrays contain arrays of other objects. Sometimes those objects are strings, sometimes other kinds of objects.

What is it you want? The string object at a particular index, or all the strings at all the array indexes combined together?

If you just need one of the strings at a particular index, you could use something like

[myArray objectAtIndex: index];  //My array is a mutable array created elsewhere

As the other poster said.

If you want to combine all the strings together, you need to write code to do that.

Something like this:

NSMutableString* combinedString;

combinedString = [NSMutableString stringWithCapacity: 50];
NSString* aString;
for (aString in myArray)
   [combinedString appendString: aString];
