Label doesn't change accordingly - ios

Question

I got the following problem: The labels always change to the ones definied in tag 9001. Could someone help me spot my error?
ViewController.m:
- (IBAction)switch0:(id)sender
{(button.tag = 9001);
UIButton *buttonPressed = (UIButton *)sender;
SecondViewController *second =[[SecondViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:second animated:YES];
second.buttonTag = buttonPressed.tag;
}
- (IBAction)switch2:(id)sender2
{ (button2.tag = 9002);
UIButton *buttonPressed = (UIButton *)sender2;
SecondViewController *third =[[SecondViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:third animated:YES];
second.buttonTag = buttonPressed.tag;
}
SecondViewcontroller.m
- (void)viewDidLoad
{
[super viewDidLoad];
if (buttonTag == 9001) {
self.label1.text = [[NSString alloc] initWithFormat:#"Radnomtext"];
self.label2.text = [[NSString alloc] initWithFormat:#"Randomtext"];
self.label3.text = [[NSString alloc] initWithFormat:#"Randomtext?"];
}
if (buttonTag == 9002) {
self.label1.text = [[NSString alloc] initWithFormat:#"Radnomtext2"];
self.label2.text = [[NSString alloc] initWithFormat:#"Randomtext2"];
self.label3.text = [[NSString alloc] initWithFormat:#"Randomtext2?"];

Answer 1

Heres an example and your presenting the view twice I took out the modal in this example:
- (IBAction)switch0:(id)sender
{
UIButton *buttonPressed = (UIButton *)sender;
SecondViewController *second =[[SecondViewController alloc] initWithNibName:nil bundle:nil];
NSInteger tagToSet = 9001;
second.buttonTag = tagToSet;;
[self.navigationController pushViewController:second animated:YES];
}
and using the keyword switch is no good. It is a reserved word in Objective C.

Answer 2

Maybe because you forgot to close the ending bracket for first if?
if (buttonTag == 9001) {
self.label1.text = [[NSString alloc] initWithFormat:#"Radnomtext"];
self.label2.text = [[NSString alloc] initWithFormat:#"Randomtext"];
self.label3.text = [[NSString alloc] initWithFormat:#"Randomtext?"];
} // bracket supposed to be here
if (buttonTag == 9002) {
or maybe you set buttonTag to incorrect instance?
- (IBAction)switch2:(id)sender2
{
UIButton *buttonPressed = (UIButton *)sender2;
SecondViewController *third =[[SecondViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:third animated:YES];
second.buttonTag = buttonPressed.tag; // supposed to be third?
[self.navigationController pushViewController:third animated:YES];
(button2.tag = 9002);
}
And to be safe, you should set buttonTag before presentModalViewController.
