I am trying to add a download progress view to my app, and while it shows in the debug preview, it does not actually show on the device. Can anyone explain this to me?
Here is a screenshot of the debug and some code:
- (void)updateDownloadProgressWithBatchIndex:(int)index contentName:(NSString *)name
{
CGSize size = self.view.bounds.size;
_loadingView = [[UIView alloc] initWithFrame:CGRectMake(75, 155, 170, 170)];
_loadingView.backgroundColor = [UIColor blackColor];
_loadingView.clipsToBounds = YES;
_loadingView.layer.cornerRadius = 10.0;
[_loadingView setCenter:CGPointMake(size.width/2, size.height/2)];
_activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
_activityView.frame = CGRectMake(65, 40, _activityView.bounds.size.width, _activityView.bounds.size.height);
_activityView.hidden = NO;
[_activityView setCenter:CGPointMake(size.width/2, size.height/2)];
[_loadingView addSubview:_activityView];
_loadingLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 115, 130, 22)];
_loadingLabel.backgroundColor = [UIColor clearColor];
_loadingLabel.textColor = [UIColor whiteColor];
_loadingLabel.adjustsFontSizeToFitWidth = YES;
_loadingLabel.textAlignment = UITextAlignmentCenter;
_loadingLabel.text = [NSString stringWithFormat:#"Batch %i downloading...", index];
[_loadingView addSubview:_loadingLabel];
[self.view addSubview:_loadingView];
_loadingView.hidden = NO;
UIView *v = self.view;
[_activityView startAnimating];
}
I'm going to take a wild guess - it has to be wild, because you refuse to show your code - that you are proceeding to synchronous networking after you call updateDownloadProgress. That's the cause of the issue. The inability of the activity view to start spinning would thus be diagnostic, the real issue being the synchronous networking, which is a no-no.

Im using the following code to get the effect similar to that of the android like progress:
-(void) showSpinner
{
NSLog(#"as");
loadingView = [[UIView alloc] initWithFrame:CGRectMake(100, 300, 170, 170)];
loadingView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5];
loadingView.clipsToBounds = YES;
loadingView.layer.cornerRadius = 10.0;
activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
activityView.frame = CGRectMake(65, 40, activityView.bounds.size.width, activityView.bounds.size.height);
[loadingView addSubview:activityView];
loadingLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 115, 130, 22)];
loadingLabel.backgroundColor = [UIColor clearColor];
loadingLabel.textColor = [UIColor whiteColor];
loadingLabel.adjustsFontSizeToFitWidth = YES;
loadingLabel.textAlignment = NSTextAlignmentCenter;
loadingLabel.text = #"Loading...";
[loadingView addSubview:loadingLabel];
loadingView .center = CGPointMake(CGRectGetWidth(self.view.frame) / 2, CGRectGetHeight(self.view.frame) / 2);
[self.statutoryTbl addSubview:loadingView];
[activityView startAnimating];
}
The issue is that the UILabel appears below the spinner. I want it to be nearby spinner and the loadingview to be wide as android. What am I missing in my code?
Initialise your loadingLabel with this code:
loadingLabel = [[UILabel alloc] initWithFrame:CGRectMake([activityView frame].origin.x+[activityView frame].size.width+20, 10, [loadingView frame].size.width-([activityView frame].origin.x+[activityView frame].size.width+20)-10, [loadingView frame].size.height-20)];
I have an app.In this app so many class methods used.I want to know is it possible to remove subview from class mehtod?
+(void)addPregressIndicator:(NSString *)strText view:(UIView *)ShowView
{
CGRect appFrame = [[UIScreen mainScreen] applicationFrame];
UIView *busyView = [[UIView alloc] initWithFrame:appFrame];
busyView.backgroundColor = [UIColor clearColor];
busyView.opaque = YES;
UIView *container = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 95, 95)];
container.layer.borderWidth = 5;
container.layer.cornerRadius = 10;
container.layer.borderColor = [UIColor whiteColor].CGColor;
[container setBackgroundColor:[UIColor blackColor]];
UIActivityIndicatorView *av = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
av.center = CGPointMake(container.center.x, 34);
av.hidesWhenStopped = NO;
[av startAnimating];
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 95, 30)];
lbl.text = strText;
lbl.textAlignment = NSTextAlignmentCenter;
lbl.center = CGPointMake(container.center.x, 70);
lbl.textColor = [UIColor whiteColor];
lbl.backgroundColor = [UIColor clearColor];
[container addSubview:av];
[container addSubview:lbl];
container.center = busyView.center;
[busyView addSubview:container];
[ShowView addSubview:busyView];
}
+(void)removePregressIndicator:(UIView *)hideView;
{
// i want remove busyview that subview in viewcontroller.
}
Please help me to remove subivew.
You can set a unique tag for the busyView like this busyView.tag = your unique tag;
And then you can remove the view with this code
+(void)removePregressIndicator:(UIView *)hideView;
{
UIView *busyView = [hideView viewWithTag:your unique tag];
if (busyView){
[busyView removeFromSuperview];
}
}
You should make sure that the busyView tag is unique for all the subviews of hideView.
Assigne tag to a each view and access the view with tag and put it
+(void)removePregressIndicator:(UIView *)hideView;
{
UIView *viewToRemove = [self.view viewWithTag:assigne_tag];
[viewToRemove removeFromSuperview];
}
+ (void)removePregressIndicator:(UIView *)hideView;
{
UIView *progView=[self.view viewWithTag:YourTag];
[progView removeFromSuperview];
}
Hi i am beginner in iOS and in my project i need to insert "titles" at "left side center" and "right side center" on UInavigationBar as like below image please help me how should i do below my requirement
See below code and try :
- (void)viewDidLoad
{
[super viewDidLoad];
CGRect frame = [[UIScreen mainScreen] bounds];
UILabel *lbl1 = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, frame.size.width/2, 44)];
lbl1.backgroundColor = [UIColor redColor];
lbl1.textAlignment = NSTextAlignmentCenter;
lbl1.text = #"Dashboard";
[self.navigationController.navigationBar addSubview:lbl1];
UILabel *lbl2 = [[UILabel alloc] initWithFrame:CGRectMake(frame.size.width/2, 0, frame.size.width/2, 44)];
lbl2.backgroundColor = [UIColor redColor];
lbl2.textAlignment = NSTextAlignmentCenter;
lbl2.text = #"Profile";
[self.navigationController.navigationBar addSubview:lbl2];
}
You can customize the titleView of navigation bar. Read the official documentation here.
As per your question, I tried the below working code:-
-(UIView *)getTitleView
{
CGRect frame = [[UIScreen mainScreen] bounds];
UIView *viewTitle = [[UIView alloc]initWithFrame:CGRectMake(0, 0, frame.size.width, self.navigationController.navigationBar.frame.size.height)];
UILabel *lbl1 = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, frame.size.width/2, self.navigationController.navigationBar.frame.size.height)];
lbl1.backgroundColor = [UIColor colorWithRed:130/255.0f green:13/255.0f blue:23/255.0f alpha:1.0f];
lbl1.textAlignment = NSTextAlignmentCenter;
[lbl1 setTextColor:[UIColor whiteColor]];
lbl1.text = #"Dashboard";
[viewTitle addSubview:lbl1];
UILabel *lbl2 = [[UILabel alloc] initWithFrame:CGRectMake(frame.size.width/2, 0, frame.size.width/2, viewTitle.frame.size.height)];
lbl2.backgroundColor = [UIColor colorWithRed:130/255.0f green:13/255.0f blue:23/255.0f alpha:1.0f];
[lbl2 setTextColor:[UIColor whiteColor]];
lbl2.textAlignment = NSTextAlignmentCenter;
lbl2.text = #"Profile";
[viewTitle addSubview:lbl2];
return viewTitle;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.titleView = [self getTitleView];
}
I divide the code in separate method to follow modular approach. For any part of code, which is of separate task, write that piece of code in different method. This will lead to more readability.
Hi I've been working with Xcode for a while and used UIGestureRecognizers many times now. At this moment i'm developing an iPad app that needs a carousel in it, so what's better then using iCarousel as i've already encountered it and I think it's great.
I'm having some issues adding to the carousel items a UISwipeGestureRecognizer (I would use it to delete the "swiped" item). Would look easy but it just looks like the UIGestureRecognizer is not there, but if print view.recognizer I can see it is actually there. What am I missing?
And sorry for any language mistakes!
The code
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UILabel *nameLabel = nil;
UILabel *notesLabel = nil;
UIImageView *icon1 = nil;
UIImageView *icon2 = nil;
Notebook *referenceNotebook = [_notebookArray objectAtIndex:index];
//create new view if no view is available for recycling
if (view == nil)
{
view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 250.0f, 373.0f)];
((UIImageView *)view).image = [UIImage imageNamed:#"notebookBase"];
view.contentMode = UIViewContentModeCenter;
CGPoint startingPoint = view.frame.origin;
CGSize startingSize = view.frame.size;
nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(startingPoint.x, startingPoint.y + 60, startingSize.width, 100)];
nameLabel.backgroundColor = [UIColor clearColor];
nameLabel.textAlignment = NSTextAlignmentCenter;
nameLabel.font = [FontController useFontKlinic_Light:50];
nameLabel.tag = 1;
[view addSubview:nameLabel];
notesLabel = [[UILabel alloc]initWithFrame:CGRectMake(startingPoint.x, startingPoint.y + 95, startingSize.width, 100)];
notesLabel.backgroundColor = [UIColor clearColor];
notesLabel.textAlignment = NSTextAlignmentCenter;
notesLabel.font = [FontController useFontKlinic_Light:30];
[view addSubview:notesLabel];
icon1 = [[UIImageView alloc] initWithFrame:CGRectMake(startingPoint.x + 105, startingPoint.y + 18, 40, 40)];
icon1.image = [UIImage imageNamed:#"notebookIcon1"];
[view addSubview:icon1];
icon2 = [[UIImageView alloc] initWithFrame:CGRectMake(startingPoint.x + 105, startingPoint.y + 320, 40, 40)];
icon2.image = [UIImage imageNamed:#"notebookIcon1"];
[view addSubview:icon2];
//UIView *swipeView = [[UIView alloc] initWithFrame:CGRectMake(startingPoint.x, startingPoint.y, startingSize.width, startingSize.height)];
//swipeView.backgroundColor = [UIColor clearColor];
//UISwipeGestureRecognizer *swipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(carouselSwipewipeHandler:)];
//[swipeRecognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
// [swipeView addGestureRecognizer:swipeRecognizer];
//[view addSubview:swipeView];
}
else
{
//get a reference to the label in the recycled view
nameLabel = (UILabel *)[view viewWithTag:1];
}
nameLabel.text = referenceNotebook.name;
notesLabel.text = #"n note";
UISwipeGestureRecognizer *swipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(carouselSwipewipeHandler:)];
[swipeRecognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
[view addGestureRecognizer:swipeRecognizer];
view.tag = index;
NSLog(#"gesture recogs: %#", view.gestureRecognizers);
return view;
}
Anyone with an idea of what I am doing wrong?
Here's also a link to the iCarousel documentation:
https://github.com/nicklockwood/iCarousel#detecting-taps-on-item-views Thanks in advance!
Only one gesture can be active at any one time by default, and the carousel uses a gesture internally for scrolling. So, if you want to use other gestures you need to add a delegate to your gesture and the the carousel gesture so that you can make them work simultaneously.
I have been searching for quite a while now, and every answer I find doesn't seem to work. I have a view, code below, that holds a bunch of text that is pulled from a YouTube video description from another view. Obviously ever video's descriptions are of different length, which is what poses the problem. I want to make it that the scrollview only scrolls down to about 10 pixels after the last text line of the label.
In this code, I don't have it doing that, I have it at a fixed size.
Can ANYONE help? I have been searching for days now, and I can seem to find a proper solution.

In short, you can use the NSString method -sizeWithFont:forWidth:lineBreakMode: to determine how tall the string will render in a container with the given width and line break mode. You can use that to size your UILabel and to set the scrollview's contentsize appropriately.
Try using sizeToFiton the label, then setting the scrollView's contentSize:
[label sizeToFit];
[scrollView setContentSize:CGSizeMake(CGRectGetWidth(self.view.frame), CGRectGetHeight(label.frame) + 10)];
Using sizeToFit is really nice, just make sure your label is already the right width before you call it.
