I'm using Paged UIScrollView with an embedded UIPageControl like explained at https://github.com/romaonthego/REPagedScrollView.
The code works fine when I use
UIView *page1 = [[UIView alloc] initWithFrame:CGRectMake(20, 20, 280, self.view.frame.size.height - 40)];
page1.backgroundColor = [UIColor lightGrayColor];
[scrollView addPage:page1];
But I need to use a nib file for my project. I'm calling it like :
UIView *page1 = [[[NSBundle mainBundle] loadNibNamed:#"mySubViewController" owner:self options:nil] objectAtIndex: 0];
page1 = [[UIView alloc] initWithFrame:CGRectMake(20, 20, 280, self.view.frame.size.height - 40)];
page1.backgroundColor = [UIColor lightGrayColor];
[scrollView addPage:page1];
Which almost works fine, I can call the view, only problem is that the view does not listen to initWithFrame:CGRectMake, it loads full screen and I can not see the page control anymore to navigate.
Autolayout is set to off.
Could anyone point me where I am wrong here ? What I could do to solve this issue ?
Best regards,

You can set frame of any view manually with method -(void)setFrame:(CGRect)frame
UIView *page1 = [[[NSBundle mainBundle] loadNibNamed:#"mySubViewController" owner:self options:nil] objectAtIndex: 0];
page1.backgroundColor = [UIColor lightGrayColor];
page1.frame = CGRectMake(20, 20, 280, self.view.frame.size.height - 40);
[scrollView addPage:page1];

I'm trying to add a label to a UIView in a xib file. When I run the app, the label doesn't shows up.
- (void)viewDidLoad {
[super viewDidLoad];
self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 200)];
[self.label setText:#"This is a label"];
xibView *myxibView = [[xibView alloc] init];
[myxibView.myView addSubview:self.label];
}
1.If your controller has the same name with your xib,
For example,XibViewController.m & XibViewController.xib.
Your controller will set its view to an instance of XibViewController.xib by default.
On this condition, you just need to add the label to the self.view
[self.view addSubview:self.label];
2.If you want to load the XibViewController.xib to an different name controller like View2Controller.m, you need load the xib by name and and add the xib view to View2Controller's view.
UIView *myxibView = [[[NSBundle mainBundle] loadNibNamed:#"XibViewController" owner:self options:nil] objectAtIndex:0];
[myxibView addSubview:self.label];
[self.view addSubview:myxibView];
xibView *myxibView = [[xibView alloc] init];
[myxibView.myView addSubview:self.label];
You didn't added myxibView to actual view. Its just an instance. Why don't you do this:
[self.view addSubview:self.label];
Hope this helps.. :)
Simply add ,
self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 200)];
[self.label setText:#"This is a label"];
[self.view addSubview:self.label];
It will subView the label on the view.
I am facing a really strange issue:
I am instantiating multiple UIImageView inside a for loop with the method CGRectMake, the y origin I am giving seems to be totally wrong on the screen:
Here is my code:
- (void)makeTheView
{
self.view.backgroundColor = [UIColor whiteColor];
UIScrollView *header = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 64, self.view.frame.size.width, 100)];
header.backgroundColor = [UIColor colorWithRed:254/255.0f green:255/255.0f blue:213/255.0f alpha:1.0f];
[self.view addSubview:header];
for (int i = 0; i < 10; i++) {
UIImageView *avatar = [[UIImageView alloc] initWithFrame:CGRectMake(5 + i * 75, 5, 70, 70)];
avatar.image = [UIImage imageNamed:#"bo_pic_baby5.jpg"];
[avatar.layer setCornerRadius:8.0];
avatar.layer.masksToBounds = YES;
NSLog(#"%f", avatar.frame.origin.y);
UILabel *title = [[UILabel alloc] initWithFrame:CGRectMake(0, 50, avatar.frame.size.width, 20)];
title.backgroundColor = [UIColor colorWithRed:148/255.0f green:148/255.0f blue:148/255.0f alpha:0.5f];
title.font = [UIFont fontWithName:#"Arial" size:15];
title.text = #"崔健";
title.textAlignment = NSTextAlignmentCenter;
title.textColor = [UIColor whiteColor];
[avatar addSubview:title];
[header addSubview:avatar];
}
}
According to this code avatar is within header at 5px from the top of header.
But the following is what I obtain visually:
note: when the white area begin, the header view stopped
This is not a real issue since I can reevaluate my frames like this :
CGRectMake(5 + i * 75, - 20, 70, 70)
but it looks really weird, and I am quite sure I am missing something totally trivial here...
I think this will be fixed by:
self.automaticallyAdjustsScrollViewInsets = NO;
Since iOS 7, view controllers automatically adjust scroll view insets so that the scroll view content is not hidden behind the navigation bar because it expects scroll views to start at the top of the screen.
However, the usual solution is to just set the scrollview frame.origin.y to 0.
Your Code is Absolutely Correct , As you are Adding the scrollview on (0,64) Position , So 64 will be count from Bottom of the Navigation Bar, If you want it on top (Just Below the Navigation bar), Change this declaration to as below :
UIScrollView *header = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 100)];
I am trying to create a scrollable view in an iOS app. If I do this programmatically, everything works fine, like in:
CODE A
- (void) loadView {
[super loadView];
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame: [[UIScreen mainScreen] bounds]];
scrollView.backgroundColor = [UIColor whiteColor];
scrollView.frame = self.view.frame;
CGRect tfRect = CGRectMake(20, 70, 240, 30);
UILabel *tf = [[UILabel alloc] initWithFrame:tfRect];
tf.text = #"Some additional text!";
[scrollView addSubview:tf];
scrollView.contentSize = CGSizeMake(320.0, 1000.0)
[self setView: scrollView];
}
Unfortunately I have a rather complex view layout, so I designed it in a nib/xib. But, when I load that into nib into the scroll view ... it does not scroll.
CODE B
- (void) loadView {
[super loadView];
UIScrollView *scrollView = [[[NSBundle mainBundle] loadNibNamed:#"TOGPraiseController" owner:self options:nil] objectAtIndex:0];
scrollView.backgroundColor = [UIColor whiteColor];
scrollView.contentSize = CGSizeMake(320.0, 1000.0)
[self setView: scrollView];
}
The content loads fine, but no matter which attributes of the view I change, it never ever scrolls. If I allow bouncing, I can see, that even all elements (subviews) below the bottom are there and I can drag them into view temporarily. But then they bounce back. And scroll indicators never appear.
What am I doing wrong. Which attributes do I have to set in the UIScrollView, so that scrolling is enabled. It seems that the interface editor of XCode sets some attributes, which prohibit scrolling.
Creating a view with following code.
- (void)loadView {
paintView=[[UIView alloc]initWithFrame:CGRectMake(0, 50, 320, 430)];
[paintView setBackgroundColor:[UIColor yellowColor]];
self.view = paintView;
[paintView release];
But my problem is whole screen fills with yellow color, but I want with specified frame.
I am creating this view in a view based application.. Am i doing something wrong, Overridind the original view?
You can do it in following way.
- (void)loadView {
/// make a empty view to self.view
/// after calling [super loadView], self.view won't be nil anymore.
[super loadView];
paintView=[[UIView alloc]initWithFrame:CGRectMake(0, 50, 320, 430)];
[paintView setBackgroundColor:[UIColor yellowColor]];
[self.view addSubview:paintView];
[paintView release];
};
UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,35)];
newView.backgroundColor=[UIColor clearColor];
UITextView *mytext = [[UITextView alloc] initWithFrame:CGRectMake(5.0, 0.0, 100.0, 28.0)];
mytext.backgroundColor = [UIColor clearColor];
mytext.textColor = [UIColor blackColor];
mytext.editable = NO;
mytext.font = [UIFont systemFontOfSize:15];
mytext.text = #"Mytext";
mytext.scrollEnabled=NO;
[mytext release];
[newView addSubview:mytext];
[self.view addSubview:newView];
replace self.view =paintView;
by
[self.view addSubview: paintView];
I am Going change Line No 3 in LoadView Method , you should add the subView in main View instead on assiging it Directly.
[self.view addSubview:paintview];
I am designing a viewcontroller which have several button bar, each bar canbe clicked and show a content view.like:
http://i.stack.imgur.com/m5V4Q.png
When I click the buttonbar, it's frame will expand bigger, and you can see the content in it(which is a button).
First, a bar button(320*30 size) and a contentView is a set, they are subviews of listview. And several listview makes the whole view.
Second, when I click it, the list view will expand from 320*30 to 320*180, the contentview in it will expand from 300*0 to 300 * 130(20 pixel of margin). and I set the clipsToBounds of contentview to Yes to make sure the content in contentview won't show when the frame height is 0.
Now,the click can show the contentview exactly as I want. But here is a problem: I can't click the button in it, and I tried to set their userInteractionEnabled to yes . And even I set the contentview as user-defined,which I set the view's userInteractionEnabled to yes and overwrite the touchbegin function to show a alertView. Those test are failed, no reaction found. And I checked and sure that there shouldn't be any view covered it.
What's the reason might be?
The code of setup the list view is:
NSArray *array = [titleArray objectAtIndex:i];
NSString *ShenSuoTitle = [array objectAtIndex:0];
NSString *ShenSuoContent = [array objectAtIndex:1];
UIView *listView = [[UIView alloc] initWithFrame:CGRectMake(0, totalHeight, 320, ShenSuoViewHeight)];
[listView setBackgroundColor:[UIColor blackColor]];
[listView setTag:[[NSString stringWithFormat:#"%d",(i+1)] intValue]];
[self.scrollView addSubview:listView];
totalHeight = totalHeight + 1 + ShenSuoViewHeight;
UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, ShenSuoViewHeight)];
[titleView setBackgroundColor:[UIColor whiteColor]];
[titleView setTag:[[NSString stringWithFormat:#"%d1",i+1] intValue]];
[listView addSubview:titleView];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setTag:[[NSString stringWithFormat:#"%d2",i+1] intValue]];
[btn setFrame:CGRectMake(0, 0, 320, ShenSuoViewHeight)];
[btn addTarget:self action:#selector(reSetFrame:) forControlEvents:UIControlEventTouchUpInside];
[titleView addSubview:btn];
UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(5, 12, 30, 30)];
img.image = [UIImage imageNamed:#"list_ico.png"];
[img setTag:[[NSString stringWithFormat:#"%d3",i+1] intValue]];
[titleView addSubview:img];
NSLog(#"img:%f,%f",img.frame.origin.y,img.frame.size.height);
UILabel *labTitle = [[UILabel alloc] initWithFrame:CGRectMake(35, 15, 100, 25)];
labTitle.textColor = [UIColor blackColor];
labTitle.backgroundColor = [UIColor clearColor];
labTitle.font = [UIFont boldSystemFontOfSize:15];
labTitle.text = ShenSuoTitle;
[titleView addSubview:labTitle];
NSLog(#"labTitle:%f,%f",labTitle.frame.origin.y,labTitle.frame.size.height);
//add a label for selected
UILabel *selectedLabel = [[UILabel alloc] initWithFrame:CGRectMake(214, 14, 86, 21)];
selectedLabel.textColor = [UIColor grayColor];
//selectedLabel.alpha = 0.75;
selectedLabel.backgroundColor = [UIColor clearColor];
selectedLabel.text = #"All";
selectedLabel.font = [UIFont boldSystemFontOfSize:15];
[selectedLabel setTag:[[NSString stringWithFormat:#"%d5",i+1] intValue]];
[titleView addSubview:selectedLabel];
NSLog(#"selectedLabel:%f,%f",selectedLabel.frame.origin.y,selectedLabel.frame.size.height);
UIView *content = [[UIView alloc] initWithFrame:CGRectMake(10, 10 + ShenSuoViewHeight, 300, 0)];
content.backgroundColor = [UIColor grayColor];
UILabel *testLa = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 30)];
testLa.text = #"Label";
UIButton *testBut = [UIButton buttonWithType:UIButtonTypeRoundedRect];
testBut.frame = CGRectMake(0, 40, 100, 30);
testBut.titleLabel.textColor = [UIColor greenColor];
testBut.titleLabel.text = #"Button";
content.tag = [[NSString stringWithFormat:#"%d4",i+1] intValue];
[content addSubview:testLa];
[content addSubview:testBut];
content.clipsToBounds = YES;
[testLa release];
[listView addSubview:content];
[content release];
[labTitle release];
[img release];
[titleView release];
[listView release];
the code handle the click to make the list view expands is:
UIView *titleView = (UIView *)[self.view viewWithTag:[[NSString stringWithFormat:#"%d1",i+1] intValue]];
titleView.backgroundColor = [UIColor colorWithRed:0.92 green:0.92 blue:0.92 alpha:0.9];
UIView *listView = (UIView *)[self.view viewWithTag:[[NSString stringWithFormat:#"%d",i+1] intValue]];
listView.frame = CGRectMake(0, totalHeight, 320, ShenSuoViewHeight);
totalHeight = totalHeight + 1 + 20 + 180 + ShenSuoViewHeight;
UIView *content = [self.view viewWithTag:[[NSString stringWithFormat:#"%d4",i+1] intValue]];
content.frame = CGRectMake(10, 10 + ShenSuoViewHeight, 300, 180);
UIImageView *img = (UIImageView*)[self.view viewWithTag:[[NSString stringWithFormat:#"%d3",i+1] intValue]];
img.image = [UIImage imageNamed:#"list_ico_d.png"];
I'm not sure I follow your situation exactly, and some code would be nice. To answer your question though, the reason is most likely that the touch is being intercepted elsewhere. It may also be that you just forgot to connect an action method to the button. Try using breakpoints or NSLogs to see what methods are being triggered and which aren't.
Thanks a lot. It is due to my fault. The code of expanding the bar which setting the listview's frame is wrong, it should add in the expanded height. This leads the visual is ok but the clicking not be handled.
So this problem closed.
