Resize button / image by user's choice - ios

,I would like to give the user the option to select the button size as per the user's choice ... Can I do this please?

Horizontally distribute three buttons evenly ios

I have three UIButtons and a holder UIView I want all my three UIButton to be vertically centred inside the UIView and also I want them to be distributed equal horizontally
float ycentre = CGRectGetMidY(self.buttonHolderView.bounds);
float xposition = (self.buttonHolderView.frame.size.width - 135.0f)/4.0f;
self.button1 = [[UIButton alloc]initWithFrame:CGRectMake(xposition,0, 45, 30)];
self.button1.center = CGPointMake(self.button1.frame.origin.x, ycentre);
self.button2 = [[UIButton alloc]initWithFrame:CGRectMake((xposition*2)+45,0, 45, 30)];
self.button2.center = CGPointMake(self.button2.frame.origin.x, ycentre);
self.button3 = [[UIButton alloc]initWithFrame:CGRectMake((xposition*3)+90,0, 45, 30)];
self.button3.center = CGPointMake(self.button3.frame.origin.x, ycentre);
[self.button3 addTarget:self action:#selector(ShareButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[self.buttonHolderView addSubview:self.button1];
[self.buttonHolderView addSubview:self.button2];
[self.buttonHolderView addSubview:self.button3];
Each button has height 30 and width 45 , but my code doesn't distribute them equally what is wrong?
Place them in a UIStackView. It makes spacing views evenly quite easy.
Set the frame of your buttons as follows and do Not set center
float thirdOfWidth = (self.buttonHolderView.frame.width/3.0);
float buttonWidth = 45.0;
float buttonHeight = 30.0;
self.button1 = [[UIButton alloc]initWithFrame:CGRectMake(thirdOfWidth*0 + (thirdOfWidth - buttonWidth)/2, (self.buttonHolderView.frame.height - buttonHeight)/2, 45, 30)];
self.button2 = [[UIButton alloc]initWithFrame:CGRectMake(thirdOfWidth*1 + (thirdOfWidth - buttonWidth)/2, (self.buttonHolderView.frame.height - buttonHeight)/2, 45, 30)];
self.button3 = [[UIButton alloc]initWithFrame:CGRectMake(thirdOfWidth*2 + (thirdOfWidth - buttonWidth)/2, (self.buttonHolderView.frame.height - buttonHeight)/2, 45, 30)];
It can be done also in loop with arbitrary count of buttons
NSInteger count = 3;
CGFloat buttonWidth = 45;
CGFloat buttonHeight = 30;
CGFloat x = (self.bounds.size.width - buttonWidth) / 2;
CGFloat verticalSpacing = ((self.bounds.size.height - buttonHeight * count) / count) - buttonHeight / 2;
CGFloat y = verticalSpacing;
for (int i = 0; i < count; i++) {
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(x, y, buttonWidth, buttonHeight)];
[self addSubview:button];
y += buttonHeight + verticalSpacing;
}

ScrollView doesn't work on iPad but works on iPhone

I have a scrollview and it is full off buttons. this scrollview work iphone but not work on ipad
#define scrollViewSizeForiPad 1000
#define scrollViewSizeForiPhone 600
#define locationButtonSizeForiPhone 50
#define locationButtonSizeForiPad 30
i added buttons like this
lc_button.frame = CGRectMake(0, 0, buttonSize, buttonSize);
[_uiScrollForLocations addSubview:lc_button];
and some labels
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){
buttonSize = buttonWidthHeightForiPad;
lc_label.font = [UIFont systemFontOfSize:14];
lc_label.frame = CGRectMake(3, 100, buttonSize, 20);
} else {
buttonSize = buttonWidthHeightForiPhone;
lc_label.font = [UIFont systemFontOfSize:9];
lc_label.frame = CGRectMake(8, 50, buttonSize, 10);
}
[_uiScrollForLocations addSubview:lc_label];
-(void) showLocations:(NSMutableArray *)lc_array {
[self hideAllLocations];
[self addButtonToView:lc_array whichView:_uiScrollForLocations type:#"Location"];
CGSize pagesScrollViewSize = _uiScrollForLocations.frame.size;
int viewHeight;
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){
viewHeight = buttonWidthHeightForiPad;
} else {
viewHeight = buttonWidthHeightForiPhone;
}
_uiScrollForLocations.contentSize = CGSizeMake(pagesScrollViewSize.width, viewHeight);}
It happen because contentSize <= _uiScrollForLocations.frame
Need set
_uiScrollForLocations.alwaysBounceVertical = YES
or
_uiScrollForLocations.alwaysBounceHorizontal = YES

iOS, create custom popover style UIView

I know there is alot of documentation on this topic, and from what i've read i've learned a lot. My issue here is that i began creating a custom UIView within a viewcontroller & now when i'm trying to make it the UIView its own class, so as to be called & used within a working app, i'm pretty confused as to what i need to do to achieve it.
The overall aim of the class is to be able to select a button one a view controller, which will instantiate the custom view, then display. The visual effect for the user is that they click the button, then a window will animate-appear from the bounds of the button (although the code below uses the positioning of top left currently), then display a combination of switches & labels, along with a back & save button.
You can see from my code that what i need to achieve this process, i've managed to implement into a single function (again, this was from creating it within a viewcontroller). What i'm after now, and can't quite fathom out is for the custom view to be imported, then on the action of the main view controller's button, add the view to self.view.
- (void)makeBox{
//view bounds
CGFloat viewWidth = CGRectGetWidth(self.view.frame);
CGFloat viewHeight = CGRectGetHeight(self.view.frame);
//red box x, y & size
CGFloat startx = (viewWidth / 100) * 10;
CGFloat starty = (viewHeight /100) * 20;
CGFloat width = (viewWidth / 100) * 80;
CGFloat height = (viewHeight /100) * 70;
CGRect view1Frame = CGRectMake(startx, starty, width, height);
//label & switch frame
CGRect labelMR = CGRectMake(10, ((height / 100) * 12), ((width / 100) * 80) - 7.5, 25);
CGRect switchMR = CGRectMake(((width / 100) * 80) + 7.5, ((height / 100) * 11), ((width / 100) * 10), 15);
//this is repeated for 6 other labels & switches
CGRect backButtonR = CGRectMake(5, 5, 50, 35);
CGRect saveButtonR = CGRectMake((width - 50), 5, 50, 35);
if (!self.view1) {
self.switchM = [[UISwitch alloc] initWithFrame:switchMR];
self.switchM.tag = 10;
if(self.monday){ //self.monday refers to a BOOL property of the viewcontroller that this was originally made in
self.switchM.on = true;
} else{
self.switchM.on = false;
}
[self.switchM addTarget:self action:#selector(switched:) forControlEvents:UIControlEventTouchUpInside];
// this switch instantiation process is repeated 6 other times
self.backButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.backButton addTarget:self
action:#selector(hideBox)
forControlEvents:UIControlEventTouchUpInside];
[self.backButton setTitle:#"Back" forState:UIControlStateNormal];
self.backButton.frame = backButtonR;
self.saveButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.saveButton addTarget:self
action:#selector(daysChanged)
forControlEvents:UIControlEventTouchUpInside];
[self.saveButton setTitle:#"Save" forState:UIControlStateNormal];
self.saveButton.frame = saveButtonR;
self.labelM = [[UILabel alloc] initWithFrame:labelMR];
self.labelM.layer.masksToBounds = YES;
self.labelM.layer.cornerRadius = 5;
self.labelM.layer.borderColor = [UIColor blackColor].CGColor;
self.labelM.layer.borderWidth = .5;
self.labelM.text = #" Monday";
self.labelM.backgroundColor = [UIColor whiteColor];
//again - repeated 6 times
//use this starting frame to make the 'popover' appear small at first
CGRect startFrame = CGRectMake(10, 10, 10, 10);
self.view1 = [[UIView alloc] initWithFrame:startFrame];
[self.view addSubview:self.view1];
[UIView animateWithDuration:0.5 animations:^(void){
self.view1.layer.cornerRadius = 10;
self.view1.layer.borderColor = [UIColor blackColor].CGColor;
self.view1.layer.borderWidth = .5;
[self.view1 setBackgroundColor:[UIColor lightGrayColor]];
self.view1.frame = view1Frame;
} completion:^(BOOL finished){
[self.view1 addSubview:self.labelM];
[self.view1 addSubview:self.switchM];
//repeat 6 times for other labels & switches
}];
}
else {
[UIView animateWithDuration:0.3 animations:^() {
self.view1.frame = view1Frame;
} completion:^(BOOL finished) {
self.labelM.frame = labelMR;
self.switchM.frame = switchMR;
//repeated for the other 6
self.backButton.frame = backButtonR;
self.saveButton.frame = saveButtonR;
}];
}
}
-(void) hideBox{
//back button was selected
[UIView animateWithDuration:0.5 animations:^(void){
[self.view1 removeFromSuperview];
self.view1 = nil;
}];
}
I understand that as i'm doing/calling this via code, i need to override either init or initWithFrame:. Do i pass the initWithFrame: the containing view controllers bounds, of which the custom view can be calculated on, and how do i handle the animation?
I've managed to set up the delegate protocol which will notify when the save button is pressed. that part i understand, its just the rest of the parts i'm unclear on.
First some background.
Typically for a popover controller, you have a single transparent root view which contains the popover view itself. This root view is the size of the containing window and usually higher in z-order than all other views. There are two reasons for this:
1) The popover needs to draw on top of all other views. If the root view wasn't on top of all other views, the popover could be clipped and not draw all of its contents.
2) The user usually needs some place to tap and dismiss the popover (effectively a cancel action).
UIPopoverController does this as do some 3rd party popovers. Some even go so far as to use their own UIWindows.
To answer your specific questions:
1) initWithFrame: / setFrame: should be passed a CGRect that is in the coordinate space of the view that will contain the view. In other words, the superview. If you decide to use a transparent root view, the popover (the part that draw on screen) will be passed a CGRect in the coordinate space of the transparent root view.
2) Usually a popover is animated like so:
// set initial frame
popover.frame = CGRectMake(x, y, width, 0);
popover.alpha = 0.0;
[rootView addSubview:popover];
[UIView animateWithDuration:0.5
animations:^{
CGRect frame = popover.frame;
frame.size.height = some-height;
popover.frame = frame;
popover.alpha = 1;
}
];
I actually got it to work! (although i can't promise this is the cleanest or most resourceful way - we'll work on that).
Here's what i did:
Split the makeBox function into 3 function, initWithWidth:andHeight:forView, openBox & updateBoxWithWidth:andHeight.
I used a saveButton delegate method that informs the parent that save button has been pressed.
.h
#protocol BoxDelegate
-(void) daysChanged;
#end
__weak id <BoxDelegate> delegate;
#interface aBox : UIView
#property (nonatomic) BOOL monday;
#property (nonatomic, weak) id <BoxDelegate> delegate;
//property values for the custom view
-(id) initWithWidth: (CGFloat) width andHeight: (CGFloat) height withView: (UIView*) theView;
-(void) updateViewWithWidth: (CGFloat) width andHeight: (CGFloat) height;
-(void) openBox;
#end
.m
#synthesize delegate;
-(id) initWithWidth:(CGFloat)inWidth andHeight:(CGFloat)inHeight withView: (UIView*) theView{
self = [super init];
self.mainView = theView;
//super view bounds
self.viewWidth = inWidth;
self.viewHeight = inHeight;
//red box x, y & size
CGFloat startx = (self.viewWidth / 100) * 10;
CGFloat starty = (self.viewHeight /100) * 20;
self.width = (self.viewWidth / 100) * 80;
self.height = (self.viewHeight /100) * 70;
self.view1Frame = CGRectMake(startx, starty, self.width, self.height);
//label & switch frame
self.labelMR = CGRectMake(10, ((self.height / 100) * 12), ((self.width / 100) * 80) - 7.5, 25);
self.switchMR = CGRectMake(((self.width / 100) * 80) + 7.5, ((self.height / 100) * 11), ((self.width / 100) * 10), 15);
//repeated for the other 6
self.backButtonR = CGRectMake(5, 5, 50, 35);
self.saveButtonR = CGRectMake((self.width - 50), 5, 50, 35);
self.switchM = [[UISwitch alloc] initWithFrame:self.switchMR];
self.switchM.tag = 10;
if(self.monday){
self.switchM.on = true;
} else{
self.switchM.on = false;
}
[self.switchM addTarget:self action:#selector(switched:) forControlEvents:UIControlEventTouchUpInside];
self.labelM = [[UILabel alloc] initWithFrame:self.labelMR];
self.labelM.layer.masksToBounds = YES;
self.labelM.layer.cornerRadius = 5;
self.labelM.layer.borderColor = [UIColor blackColor].CGColor;
self.labelM.layer.borderWidth = .5;
self.labelM.text = #" Monday";
self.labelM.backgroundColor = [UIColor whiteColor];
//repeated for the other 6
self.saveButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.saveButton addTarget:delegate
action:#selector(daysChanged)
forControlEvents:UIControlEventTouchUpInside];
[self.saveButton setTitle:#"Save" forState:UIControlStateNormal];
self.saveButton.frame = self.saveButtonR;
return self;
}
-(void) openBox{
CGRect startFrame = CGRectMake(10, 10, 10, 10);
self.view1 = [[UIView alloc] initWithFrame:startFrame];
[self.mainView addSubview:self.view1];
[UIView animateWithDuration:0.5 animations:^(void){
self.view1.layer.cornerRadius = 10;
self.view1.layer.borderColor = [UIColor blackColor].CGColor;
self.view1.layer.borderWidth = .5;
[self.view1 setBackgroundColor:[UIColor lightGrayColor]];
// repeated for the other 6
self.view1.frame = self.view1Frame;
} completion:^(BOOL finished){
[self.view1 addSubview:self.labelM];
[self.view1 addSubview:self.switchM];
[self.view1 addSubview:self.backButton];
[self.view1 addSubview:self.saveButton];
}];
}
-(void) updateViewWithWidth: (CGFloat) width andHeight:(CGFloat) height{
//re-calculate
self.viewWidth = width;
self.viewHeight = height;
CGFloat startx = (self.viewWidth / 100) * 10;
CGFloat starty = (self.viewHeight /100) * 20;
self.width = (self.viewWidth / 100) * 80;
self.height = (self.viewHeight /100) * 70;
self.view1Frame = CGRectMake(startx, starty, self.width, self.height);
//label & switch frame
self.labelMR = CGRectMake(10, ((self.height / 100) * 12), ((self.width / 100) * 80) - 7.5, 25);
self.switchMR = CGRectMake(((self.width / 100) * 80) + 7.5, ((self.height / 100) * 11), ((self.width / 100) * 10), 15);
self.backButtonR = CGRectMake(5, 5, 50, 35);
self.saveButtonR = CGRectMake((self.width - 50), 5, 50, 35);
[UIView animateWithDuration:0.3 animations:^() {
self.view1.frame = self.view1Frame;
} completion:^(BOOL finished) {
self.labelM.frame = self.labelMR;
self.switchM.frame = self.switchMR;
self.backButton.frame = self.backButtonR;
self.saveButton.frame = self.saveButtonR;
}];
}
And then in our parent viewcontroller
#property aBox *theBox;
...
- (void)viewDidLoad {
[super viewDidLoad];
self.theBox = [[aBox alloc] initWithWidth:self.view.frame.size.width andHeight:self.view.frame.size.height withView:self.view];
[self.theBox openBox];
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
[self.theBox updateViewWithWidth:self.view.frame.size.width andHeight:self.view.frame.size.height];
}
- (void) daysChanged{
NSLog(#"Days Changed!");
}

Set button position in SBTableAlert

I was using SBTableAlert library in my app, but with iOS 7 this library won't work.
I fix it whit adding TSAlertView and dialogs are showing fine.
But my problem is that position of button is not as it should be.
I set position of the button in :
-(void)willPresentTableAlert:(SBTableAlert *)tableAlert{
int counter = 0;
for (id view_sub in self.filterAlert.view.subviews) {
if ([view_sub isKindOfClass:[UIButton class]]) {
switch (counter) {
case 0:
((UIButton*)view_sub).frame = CGRectMake(10,
10,
144,
44);
((UIButton*)view_sub).backgroundColor = [UIColor redColor];
break;
case 1:
((UIButton*)view_sub).frame = CGRectMake(169,
150,
144,
44);
break;
case 2:
((UIButton*)view_sub).frame = CGRectMake(328,
150,
144,
44);
break;
default:
break;
}
counter++;
}
}
}
The thing is that button is painted red but frame set is ignored, instead of lining in one line, they are put one under the other and out of the Alert frame.
I finally found the answer.
The problem was in TSAlertVeiw library, because it has function recalcSizeAndLayout:layout which is called at the end and overwrite your custom position of the buttons.
The solution was to add new BOOL variable in TSAlertView customLayoutOfButton and then check it before auto layout your buttons:
if (!self.customLayoutOfButton) {
CGFloat buttonHeight = [[self.buttons objectAtIndex:0] sizeThatFits: CGSizeZero].height;
if ( stacked )
{
CGFloat buttonWidth = maxWidth;
for ( UIButton* b in self.buttons )
{
b.frame = CGRectMake( kTSAlertView_LeftMargin, y, buttonWidth, buttonHeight );
y += buttonHeight + kTSAlertView_RowMargin;
}
}
else
{
CGFloat buttonWidth = (maxWidth - kTSAlertView_ColumnMargin) / 2.0;
CGFloat x = kTSAlertView_LeftMargin;
for ( UIButton* b in self.buttons )
{
b.frame = CGRectMake( x, y, buttonWidth, buttonHeight );
x += buttonWidth + kTSAlertView_ColumnMargin;
}
}
}

How to make iPad rotations more fluid?

I'll show you two methods: the first one "redefineLayout" calculate new positions of elements and the second one is the hook "didRotateFromInterfaceOrientation" after rotation.
- (void)redefineLayout
{
int margin = 20;
int buttonWidth = ((int)self.view.frame.size.width - margin * 4)/3;
[self.buttonNewOrder setFrame:CGRectMake(margin, 20, buttonWidth, 200)];
[self.buttonStatistics setFrame:CGRectMake(margin * 2 + buttonWidth, 20, buttonWidth, 200)];
[self.buttonSincronize setFrame:CGRectMake(margin * 3 + buttonWidth * 2, 20, buttonWidth, 200)];
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
[self redefineLayout];
}
My interface work but after rotations I see elements make a quick and unsightly movement. I'll like to make this movement more fluid. Any suggestion?
My solution:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
[self redesignLayout:duration];
}
- (void)redesignLayout:(NSTimeInterval)duration {
[UIView animateWithDuration:duration animations:^{
int margin = 20;
int buttonWidth = (((int)self.view.frame.size.width) - margin * 4)/3;
[self.buttonNewOrder setFrame:CGRectMake(margin, 20, buttonWidth, 200)];
[self.buttonStatistics setFrame:CGRectMake(margin * 2 + buttonWidth, 20, buttonWidth, 200)];
[self.buttonSincronize setFrame:CGRectMake(margin * 3 + buttonWidth * 2, 20, buttonWidth, 200)];
}];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self initLayout];
[self redesignLayout:0];
}
Try replacing your didRotateFromInterfaceOrientation call with this:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration
{
[UIView animateWithDuration:duration animations:^{
[self redefineLayout];
}];
}
