UIPickerView not showing images in iOS 7 + versions

Question

I'm trying to run my app in iOS 7+ versions wherein struck with one issue

I have UIPickerview showing images correctly for versions lessthan iOS 7 but in iOS 7+ entire picker view is messed up. Here's what im trying to achieve

I have array of imageViews in Viewload

Trying to display same in ViewForRow method. Please check code below

//In ViewDidLoad()
 NSArray *box12names = [[NSArray alloc] initWithObjects:@"Black",@"Brown",@"Red",@"Orange",@"Yellow",@"Green",nil];

self.box1_views = [[NSMutableArray alloc] initWithCapacity:10]; 

// From code below , Box1_Black, Box1_Brown etc... are my png images in APP

for (NSString *str in box12names) {
NSString *filename = [[NSString alloc] initWithFormat:@"Box1_%@.png",str];
UIImage *image = [UIImage imageNamed:filename];
UIImageView *imageview = [[UIImageView alloc] initWithImage:image];

[self.box1_views addObject:imageview];
[filename release];
[imageview release];

}

 [self.box1_views release];

self.box2_views = [[NSMutableArray alloc] initWithCapacity:10]; 

for (NSString *str in box12names) {
NSString *filename = [[NSString alloc] initWithFormat:@"Box2_%@.png",str];
UIImageView *imageview = [[UIImageView alloc] initWithImage:[UIImage imageNamed:filename]];

[self.box2_views addObject:imageview];
[filename release];
[imageview release];

}

[self.box2_views release];

[box12names release];


//In PickerViewDelegate method

-(UIView *)pickerView:(UIPickerView *)pickerView
   viewForRow:(NSInteger)row
 forComponent:(NSInteger)component reusingView:(UIView *)view

{

NSString *arrayName = [[NSString alloc] initWithFormat:@"box%d_views", component +1];

NSArray *array = [self valueForKey:arrayName];

UIView *tempview = [array objectAtIndex:row];

[arrayName release];

return tempview;

}



//Here my picker view is displaying wierdly with iOS 7+ version whereas works good with iOS 6

I think you didnt add subview of imageview in the pickerview's reusing view.So try this below line in pickerView:viewForRow method:

tempView.addSubview(imageView);

Put the imageView from the viewDidiLoad to ViewforRow, – dahiya_boy Dec 13 '16 at 06:22
Keep in mind, if you need imageView in more than 1 method then declare the imageview @interfave in .m file – dahiya_boy Dec 13 '16 at 06:23
code in view did load: ` NSArray *arrImage = @[@"box1.png", @"box2.png", @"box3.png", @"box4.png", @"box5.png"]; // contains name of images` code in delegate: ` UIView *tempView = [UIView new];// give frame if needed UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:arrImage[row]]]; [tempView addSubview:imgView]; return tempView;` – dahiya_boy Dec 13 '16 at 06:28

Issue resolved -

{
NSString *arrayName = [[NSString alloc] initWithFormat:@"band%d_views", component +1];
NSArray *array = [self valueForKey:arrayName];
//UIView *tempview = [array objectAtIndex:row];
UIView *tempview=[[UIView alloc] init];
[tempview setBackgroundColor:[UIColor colorWithPatternImage:[[array objectAtIndex:row] image]]];

[arrayName release];
return tempview;
}
