Picker View only selects first object from NSArray in text box - objective-c

Question

Im trying to learn how to select an object from a picker view to display in a TextBox, six hours in I thought id finally cracked but no. It works, but I can only get the first item in my NSArray to display in my text box.
Select being my picker, arrstatus is my NSArray, text1 is my text box.
Using a button to get my value: under IBAction:
NSInteger selectedRow = [select selectedRowInComponent:0];
text1.text = [arrStatus objectAtIndex:selectedRow];
[text1 resignFirstResponder];
rest of code:
.h
#interface pick5 : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate,UITextFieldDelegate>
{
UIPickerView *select;
NSArray *arrStatus;
}
.m
UIPickerView *select = [[UIPickerView alloc] initWithFrame:CGRectZero];
select.delegate = self;
select.dataSource = self;
[select setShowsSelectionIndicator:YES];
text1.inputView = select;
arrStatus = [[NSArray alloc] initWithObjects:#"bs88", #"bs60898", #"Memphis", #"California", #"Seattle",#"London",#"Paris", nil];
}
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
//One column
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
//set number of rows
return arrStatus.count;
}
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
//set item per row
return [arrStatus objectAtIndex:row];
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)viewDidUnload
{
[self setText1:nil];
[self setResign:nil];
[self setText2:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (IBAction)resign:(id)sender {
NSInteger selectedRow = [select selectedRowInComponent:0];
text1.text = [arrStatus objectAtIndex: selectedRow];
[text1 resignFirstResponder];
}
#end
im also getting yellow warning triangles local decalration of "select" hides instance variable

Answer 1

For your warning in yellow color change the following line of code in your .m file.
UIPickerView *select = [[UIPickerView alloc] initWithFrame:CGRectZero];
replace above with below:
select = [[UIPickerView alloc] initWithFrame:CGRectZero];
because you have already declared uipicker* select in .h file.
