UIPickerView inside UITableView.tableFooterView doesn't receive drag touches

I have a UIPickerView in the footer of a table (from which I plan to issue "pagination"-style requests for the table--the picker will list the pages available of the LARGE data set I'm navigating, and let the user jump straight to any "page" of the data). My picker receives taps; if I tap on a row of the picker that isn't the selected one, it rolls into the center space of the picker. But if I drag my finger on the picker, I scroll the TABLE, not the picker contents. I tried installing a UIView subclass in my tableFooterView to see if I could catch touches, and I can... but not touches on the

how to change the background color in UIPickerView?

孤街醉人 提交于 2019-12-01 11:28:05
I want to change the background color in UIPickerView , Is it possible? Ryan Booker UPDATE: One simple trick is to set the alpha on some of the subviews. Which one specifically depends on how many components you have, but the code is: [(UIView*)[[picker subviews] objectAtIndex:2] setAlpha:0.5f]; This will make the dial semi transparent and show through the background colour. Setting the backgroudColor doesn't appear to do anything. The best I have been able to do so far is set the background colour of individual component rows, which is next to useless as the base colour of the component will

UIPickerView EXC BAD ACCESS?

冷暖自知 提交于 2019-12-01 09:06:25
I keep getting a exc bad access error and I think it has something to do with my UIPickerView because this is when the app crashes. Everything works fine until I make a 9th choice from the UIPickerView. Every single time the app crashes on the 9th choice. Any ideas? - (void)viewDidLoad { [super viewDidLoad]; list = [[NSMutableArray alloc] init]; [list addObject:@"Anvil"]; [list addObject:@"Apple"]; [list addObject:@"Arrow"]; [list addObject:@"Baby"]; [list addObject:@"Basketball"]; [list addObject:@"Beehive"]; [list addObject:@"Blimp"]; [list addObject:@"Bomb"]; [list addObject:@"Bungee Jumper

How do I use multiple picker views with different data sources in the same view?

隐身守侯 提交于 2019-12-01 07:31:24
问题 I have a view with three picker views in it. Two of the picker views have the same data, an array with the numbers 1 to 100. The third picker view has an array with a list of model railroad track manufacturers in it. I have tagged the picker views using a method I found on this site, but when I run the app, all three picker views have 1 to 100 as their data. I also control-dragged from all picker views to the yellow circle at the top of the view and clicked dataSource and delegate . How do I

iOS 7 slow to open UITableViewController with UIPickerView

删除回忆录丶 提交于 2019-12-01 05:42:29
问题 Accordingly to this question and the kind answer of KyleC I've implemented a UITableViewController which has many rows relying on a fetch from Core Data. Every row display a simple NSString (name of the object fetched) and has an UIPickerView hidden. The issue is that it's absolutely evident that when I tap the row in the previous UITableViewController that opens the UITableViewController with picker views there's some delay in the segue transition. I know this because the previous

Swift UIPickerView 1st component changes 2nd components data

隐身守侯 提交于 2019-12-01 03:28:26
问题 I created this UIPickerView where the 1 components selection decides what the 2 components data is. Yet, whenever I start moving the UIPicker it throws the "libc++abi.dylib: terminating with uncaught exception of type NSException" error with Thread 1. I am guessing the data is the problem?? Not Sure var wheelPickerContents: [[String]] = [] var categories = ["Attractions & Entertainment", "Eating & Drinking", "Education", "Emergency", "Financial Institution", "Lodging Establishment", "Medical
