Indexed UILabels Objective-C

i am prog开发者_如何学Pythonramming an iphone application and need help with the UILabels. An example: I have 10 Labels named Label1, Label2, Label3 etc. and Label1.text = @"1", Label2.text=@"2" etc. is there a way to do it in a for-loop. Like for(int i = 1, i<11,i++){Labeli.text = ...} ? thx for helping.


Set tag for each label and access the value as follows,

for(int i=1; i<=10;i++)
{
    UILabel *lab=(UILabel *)[self.view viewWithTag:i];
    [lab setText:[NSString stringWithFormat:@"%d",i]];
}

or else do as follows,

NSArray *labels=[NSArray arrayWithObjects: label1, label2, nil];

int i=1;

for(UILabel *label in labels) {
  [label setText:[NSString stringWithFormat:@"%d",i]];
  i++;
}


Here's the proper for loop:

for(int i = 0; i < numLabels; i++) {
    UILabel *label = [[UILabel alloc] init];
    label.text = [NSString stringWithFormat:@"%i", i];
    // other label customizations here
    [myMutableArray addObject:label]
    [label release];
}

Then, later, access each label with [myMutableArray objectAtIndex:index];
