Auto Adjusting UIButton On a UIView

Here is a simple requirement
- You can have any number of UIButtons say from 2 to 5, you need to adjust them in the horizontal view with each tags

2 Buttons Example :

5 Buttons Example :

 #import "BGGridButtonsView.h"  
 @implementation BGGridButtonsView  
 @synthesize buttonNames;  
 -(void) baseInit {  
   int count = [buttonNames count];  
   CGFloat padding = 10;  
   CGFloat width = self.frame.size.width / count - padding;  
   for (int i = 0; i < count; i++) {  
     CGFloat ptX = i * (width + padding) ;  
     UIButton *button = [self addMyButton:i+1];  
     button.frame = CGRectMake(ptX, 0, width, 20);  
     [self addSubview:button];  
   }  
 }  
 -(void) buttonAction:(UIButton *) sender {  
   DLog(@"%d", sender.tag);  
 }  
 - (UIButton *) addMyButton:(int)tagNo  
 {  
   UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];  
   [button setTitle:buttonNames[tagNo-1] forState:UIControlStateNormal];  
   button.backgroundColor = [UIColor clearColor];  
   [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];  
   //UIImage *buttonImageNormal = [UIImage imageNamed:@""];  
   UIImage *buttonImageNormal = [UIImage imageNamed:@""];  
   UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:2 topCapHeight:2];  
   [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal];  
   //  UIImage *buttonImagePressed = [UIImage imageNamed:@""];  
   //  UIImage *strechableButtonImagePressed = [buttonImagePressed stretchableImageWithLeftCapWidth:2 topCapHeight:2];  
   //  [button setBackgroundImage:strechableButtonImagePressed forState:UIControlStateHighlighted];  
   [button addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];  
   button.tag = tagNo;  
   [self addSubview:button];  
   return button;  
 }  
 - (id)initWithFrame:(CGRect)frame  
 {  
   self = [super initWithFrame:frame];  
   if (self) {  
   }  
   return self;  
 }  
 - (void)drawRect:(CGRect)rect  
 {  
   [self baseInit];  
 }  
 @end  

Finally On your View Controller

 #import "BGGridButtonsView.h"  
 @interface TestVC : UIViewController  
  <BGGridButtonsViewDelegate>  

 -(void) viewDidAppear:(BOOL)animated   {  
   BGGridButtonsView *buttonsGrid = [[BGGridButtonsView alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];  
   buttonsGrid.buttonNames = @[ @"Call", @"PMS"];  
   buttonsGrid.tag = 1;  
   buttonsGrid.backgroundColor = [UIColor redColor];  
   [self.view addSubview:buttonsGrid];  
 }  

 #pragma mark Delegate Method  
 -(void) selectedButton:(int)buttonNo forTagNo:(int)tagNo {  
   DLog(@"%d , %d",buttonNo, tagNo);  
 }  

Create Grid Layout View Matrix Programatically

OutPut

View Controller

 #import "BGGridImagesView.h"  
 -(void) groupLayout {  
   BGGridImagesView *gridView = [[BGGridImagesView alloc] initWithFrame:CGRectMake(0, 0, 140, 100)];  
   [self.view addSubview:gridView];  
 }  

View

   NSInteger grid[10][10];  
   NSInteger k = 0;  
   for (int row = 0; row < 4; row++) {  
     for (int column = 0; column < 5; column++) {  
       k++;  
       grid[row][column] = k;  
       UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(column*30, row * 30, 20, 20)];  
       NSString *string = [[NSString alloc] init];  
       string = [NSString stringWithFormat:@"%d",k];  
       lbl.text = string;

Using UIButtons

 #pragma mark - Grid Layout  
 #define FACTOR 1.0  
 #define kHeight 85.0f  
 #define kWidth 85.0f  
 #define xPadding 15.0f

 #define kNoOfColumn 3  
 -(void) loadGridImages {  
   UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.bounds];  
   int numberOfImages = 30;  
   CGRect frame = self.frame;  
   NSInteger grid[30][30];  
   NSInteger k = 0;  
   BOOL dobreak = NO;  
   CGFloat heightFactor = ( kHeight / kNoOfColumn ) * 3;  
   CGFloat widthFactor = ( kWidth / kNoOfColumn ) * 3;  
   for (int row = 0; row < (numberOfImages / kNoOfColumn) && !dobreak; row++) {  
     for (int column = 0; column < kNoOfColumn; column++) {  
       k++;  
       grid[row][column] = k;  
       DLog(@"%d",k);  
       if (k > numberOfImages) {  
         dobreak = YES;  
         break;  
       }  
       frame.size.height = heightFactor;  
       frame.size.width = widthFactor;  
       frame.origin.x = 10 + ( heightFactor * column) + (10 * column);  
       frame.origin.y = 20 + ( widthFactor * row) + (10 * row);  
       UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];  
       NSString *string = [NSString stringWithFormat:@"%d",k];  
       [button setTitle:string forState:UIControlStateNormal];  
       button.titleLabel.font = [UIFont systemFontOfSize:30];  
       //button.backgroundColor = [UIColor blueColor];  
       [button addTarget:self action:@selector(showActionSheet:) forControlEvents:UIControlEventTouchUpInside];

   [scrollView setContentSize:CGSizeMake(self.frame.size.width - xPadding, (((numberOfImages+1)/2) * heightFactor) * 0.8)];  
   [self addSubview:scrollView];

     int j = 0;  
     if (i < 3) {

       frame.origin.x = xPadding * 2 + kWidth * 1 ;  
     } else if ((j+1) %3 == 0) {  
       frame.origin.x = xPadding * 3 + kWidth * 2;  
     }  
       
     // frame.origin.y = ((i/3) * kHeight) + yPadding * 3;  
     frame.origin.y = ((i/3) * kHeight) + yPadding * (i/3);

*( NOT A Good algorithm ) but just for example

Discover and organize Github alternate repositories

Do you use lots of framework in your project. If so you must be using Cocoapods.
But what if you want to find alternate solution to your current framework .

Try Gitrep.

For example if you want to try RestKit as framework but explore alternate framework then
go to this link
http://gitrep.com/users/RestKit/repos/RestKit
It will show u other similar alternate framework.

But if you want to learn RestKit follow this stackover flow answer.

And for facebook's popular framework three20 - which no longer supported has alternate nimbus

Happy Discovering :)
