UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:@"your image number %@.png", (long)row]];
UIImageView *temp = [[UIImageView alloc] initWithImage:img];
temp.frame = CGRectMake(-70, 10, 60, 40);
UILabel *channelLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, -5, 80, 60)];
channelLabel.text = [NSString stringWithFormat:@"%@", [your array objectAtIndex:row]];
channelLabel.textAlignment = UITextAlignmentLeft;
channelLabel.backgroundColor = [UIColor clearColor];
UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 110, 60)];

Problem
I have looked and looked on the net and not found much on this! I would like to know how you put images in a UIPicker so that each of the rows have a different image. ``` #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize pickerContent; @synthesize p1; - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } ////////// - (NSMutableArray *)pickerContent { if(!pickerContent) { pickerContent = [[NSMutableArray alloc] initWithObjects: [UIImage imageNamed:@"one.jpg"], [UIImage imageNamed:@"two.jpg"], [UIImage imageNamed:@"three.jpg"], [UIImage imageNamed:@"four.jpg"], [UIImage imageNamed:@"five.jpg"], nil]; } return pickerContent; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { if ([pickerView isEqual:p1]) { return 4; } return 0; } - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { if ([pickerView isEqual:p1]) { if (component == R1)return [self.pickerContent count]; if (component == R2)return [self.pickerContent count]; if (component == R3)return [self.pickerContent count]; if (component == R4)return [self.pickerContent count]; } return 0; } - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { if ([pickerView isEqual:p1]) { if (component== R1)return [pickerContent objectAtIndex:row]; if (component== R2)return [pickerContent objectAtIndex:row]; if (component== R3)return [pickerContent objectAtIndex:row]; if (component== R4)return [pickerContent objectAtIndex:row]; } return 0; } @end ```
