How to make my UIPickerView display all elements of an array - iphone

Question

I have a UIPickerView and an array though I can't seem to be able to input all the date from the array into the UIPicker.
I know that the syntax is meant to be like this:
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return [treatments objectAtIndex:row];
}
Where treatments is the array name though when I use this it comes up with this error:
-[Treatment isEqualToString:]: unrecognized
I have searched my entire project and can't find the phrase: isEqualToString
Treatment.h file:
#import <Foundation/Foundation.h>
#interface Treatment : NSObject {
NSString *treatmentid;
NSString *treatmentName;
NSString *treatmentPrice;
}
#property (nonatomic, strong) NSString *treatmentid;
#property (nonatomic, strong) NSString *treatmentName;
#property (nonatomic, strong) NSString *treatmentPrice;
#end
All picker codes:
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return [treatments count];
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 1;
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return [treatments objectAtIndex:row];
}
If you need any more code just say
Thanks in advance

Answer 1

you your Array contain Dictionar or NSMutableDictionar then you must specify value of array with it's key like bellow try to writtern you method like this:
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return[[treatments objectAtIndex:row]valueForKey:#"YourKey"];
}
Here is basic Implementation of Picker view sample example code:-
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thepickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)thepickerView numberOfRowsInComponent:(NSInteger)component
{
return [treatments count];
}
customize displaying lable of UIpickerview like bellow:-
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 300, 37)];
if (component == 0) {
label.font=[UIFont boldSystemFontOfSize:22];
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor clearColor];
label.text = [NSString stringWithFormat:#"%d", row];
label.font=[UIFont boldSystemFontOfSize:22];
NSLog(#"%#",[yourpickerview selectedRowInComponent:component]);
}
return label;
}
- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
NSLog(#"%#",[treatments objectAtIndex:row]);
}
