If the photo I picked from PhotoLibrary is small, the uitextivew will be fine, if the photo is large, the uitextview will be slow when I scroll or edit the uitextview, it seems stucks, how can I optimize it?
I have a UIScrollView with a list of UIViews within it. Bit like a fancy tableview. One issue I am having is the buttons work ok for the first 3 'rows' in the scrollview, but none of the buttons after this respond when i scroll down. Looks like its working ok for the buttons that show on screen when the view has loaded but anything further down when i scroll will now respond at all...

I have a problem in my App. I set a badge value at one of the tabs in the UITabBar. The Badge value is correctly red and the circle around the badge value is correctly in white. The problem is, that the color of the text is gray (160, 160, 160). It is the same color like the normal state tabbaritem text is, but I set this color nowhere in the app code and I do not know where this color come from.
I searched for that issue in the whole net since weeks but I cannot find any solution. The only answer I found everywhere is, that it is not possible to change the color of the text of the badge value. But if it is not possible, why is it changed in my app?
I hope, that somebody can help me with that issue...

I found a solution for my problem on my own:
I must remove the following lines from the overwritten UILabel:

[self setFont:[UIFont fontWithName:#"KievitPro-Regular" size:12.0]];
}
-(id)initWithFrame:(CGRect)frame
{
id result = [super initWithFrame:frame];
if (result) {
[self setFont:[UIFont fontWithName:#"KievitPro-Regular" size:12.0]];
}
return result;
}
Maybe someone can explain me, why this lines change the text color of the badge value, before we can close this post?
Instead of setting the default UILabel font using a category, use the UILabel's appearance method to set the font:
[[UILabel appearance] setFont:[UIFont fontWithName:#"KievitPro-Regular" size:12.0]];
When I tested this the text for the badge appeared as the normal white color.

I have faced one issue to display UIPickerView with a Done button in Ipad.
I done detailed researches though many links and blogs and got the suggestion as "display the UIPickerView from an UIActionSheet"
I saw many posts related this, however there is no good answers.So please dont close it as a duplicate.
Also i was able to get some good codes to do it and it worked fine in my Iphone devices.
However i were found a difficulty in Ipad devices.
The Action-Sheet is not displaying as a full view.
Please see the below screenshot.this was the result!!!
The code is used to do this is pasted below.
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:nil
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;
[actionSheet addSubview:pickerView];
[pickerView release];
UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:#"Close"]];
closeButton.momentary = YES;
closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:#selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:closeButton];
[closeButton release];
[actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
Then I have downloaded a excellent sample application from github through sample pickers
After the download, i have copied the classes only mandatory for me to my application.
The method they are using to show the UIPickerView+Done button through Action-Sheet is described below
ActionStringDoneBlock done = ^(ActionSheetStringPicker *picker, NSInteger selectedIndex, id selectedValue) {
if ([myLabel respondsToSelector:#selector(setText:)]) {
[myLabel performSelector:#selector(setText:) withObject:selectedValue];
}
};
ActionStringCancelBlock cancel = ^(ActionSheetStringPicker *picker) {
NSLog(#"Block Picker Canceled");
};
NSArray *colors = [NSArray arrayWithObjects:#"Red", #"Green", #"Blue", #"Orange", nil];//picker items to select
[ActionSheetStringPicker showPickerWithTitle:#"Select a Block" rows:colors initialSelection:0 doneBlock:done cancelBlock:cancel origin:myButton];
In the last line of code they have used the parameter as origin: and we can pass any objects (button,label etc) to it.
The Action-sheet will take origin as the passed object.
Here my issue came again :). I have used segment control to pick the time as per my conditions.
if i give mySegment as the origin parameter,the Action-sheet origin arrow will display from middle of my segment control.Not from the selected tab ,which is too bad and will give confusion to my valuable users.
So i have added individual labels under the segment sections and given it for the origin parameter of the mentioned method and i fixed my issue.
However i know its not a good fix :)
May i know is there any easy way to do it?
Is Apple support ActionSheet+UIPickerView+DoneButton in Ipad?
Any help on this issue is Appreciated

You have to use UIPopOverController.
First, create a UIPickerViewController for iPhone. You need it for the nib, which will be pushed into the popOver. Initialize the picker in ViewWithPicker
.h
#import <UIKit/UIKit.h>
#class ViewWithPickerController;
#protocol PopoverPickerDelegate
#required
- (void) viewWithPickerController:(ViewWithPickerController*) viewWithPickerController didSelectValue:(NSString*) value;
#end
#interface ViewWithPickerController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource> {
IBOutlet UIPickerView *pickerView;
id<PopoverPickerDelegate> delegate;
NSMutableArray *array;
}
#property(nonatomic, retain) IBOutlet UIPickerView *pickerView;
#property(nonatomic, assign) id<PopoverPickerDelegate> delegate;
#end
.m, after you initialized the array in viewDidLoad, picker methods:
// returns the number of 'columns' to display.
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker {
return 1;
}
// returns the number of rows in each component.
- (NSInteger)pickerView:(UIPickerView *)picker numberOfRowsInComponent:(NSInteger)component {
return [array count];
}
//returns the string value for the current row
- (NSString *)pickerView:(UIPickerView *)picker titleForRow:(NSInteger)row forComponent:(NSInteger)component {
return [array objectAtIndex:row];
}
//handle selection of a row
- (void)pickerView:(UIPickerView *)picker didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
NSString *value = [pickerView.delegate pickerView:picker titleForRow:row forComponent:component];
//notify the delegate about selecting a value
if(delegate != nil)
[delegate viewWithPickerController:self didSelectValue:value];
}
Then, import the viewWithPicker into your main class, create a button and give it this action:
- (IBAction) showPickerPopupAction:(id) sender {
self.viewWithPickerController = [[[ViewWithPickerController alloc] initWithNibName:#"ViewWithPicker" bundle:[NSBundle mainBundle]] autorelease];
viewWithPickerController.contentSizeForViewInPopover =
CGSizeMake(viewWithPickerController.view.frame.size.width, viewWithPickerController.view.frame.size.height);
viewWithPickerController.delegate = self;
self.popoverController = [[[UIPopoverController alloc]
initWithContentViewController:viewWithPickerController] autorelease];
[self.popoverController presentPopoverFromRect:popoverButtonForPicker.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
popoverController.delegate = self;
}
And to select a specific value
- (void) viewWithPickerController:(ViewWithPickerController*) viewWithPickerController didSelectValue:(NSString*) value
{
yourLabel.text = [NSString stringWithFormat:#"%# ",value];
}
Use UIPopoverController for done button in picker, create a view controller class in which take a picker and add navigation cancel and done button.
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:nextViewController];
_datePickerPopover = [[UIPopoverController alloc] initWithContentViewController:navigationController];
nextViewController.datePickerPopover = _datePickerPopover;
_datePickerPopover.delegate=self;
[_datePickerPopover setPopoverContentSize:CGSizeMake(320, 453) animated:NO];
if (isSearchOpen) {
[_datePickerPopover presentPopoverFromRect:CGRectMake(btn.frame.origin.x+10+245, btn.frame.origin.y+100-scrollPointY, 44, 44) inView:self.splitViewController.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
}
else
{
[_datePickerPopover presentPopoverFromRect:CGRectMake(btn.frame.origin.x+10+245, btn.frame.origin.y+55, 44, 44) inView:self.splitViewController.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];//
}
Try out below code for UIPicker View in iPad
