iOS-Key-Value Coding

                          Key-Value Coding

Hi Guys!
Today, I'm going to work with Key-Value Coding. To explain why we need key-Value Coding, I've an example for you
To calculate an average salary from n number of  employees, You'll use loops and some coding stuff to add all employees salary and then Calculate average divided by No. of employees.

double totalSalary = 0.0;
           for (Employee *employee in employees) {
               totalSalary += [employee.salary doubleValue];
                   }
double averageSalary = totalSalary / [employees count];

 

Fortunately, Apple Provides Key-value Coding gives us a much more concise--almost Ruby-like--way to do this:  

[employees valueForKeyPath:@"@avg.salary"]; 

Key-Value Operators used with valueForKeyPath and @ denotes a particular aggregate function

 

Collection Operators fall into one of three different categories, according to the kind of value they return:

• Simple Collection Operators return strings, numbers, or dates, depending on the operator.
• Object Operators return an array.
• Array and Set Operators return an array or set, depending on the operator.

Simple Collection Operators

• @count: Returns the number of objects in the collection as an NSNumber.
• @sum: Converts each object in the collection to a double, computes the sum, and returns the sum as an NSNumber.
• @avg: Takes the double value of each object in the collection, and returns the average value as an NSNumber.
• @max: Determines the maximum value using compare:. Objects must support comparison with one another for this to work.
• @min: Same as @max, but returns the minimum value in the collection.

Example 
[products valueForKeyPath:@"@count"]; // 4
[products valueForKeyPath:@"@sum.price"]; // 3526.00
[products valueForKeyPath:@"@avg.price"]; // 881.50
[products valueForKeyPath:@"@max.price"]; // 1699.00
[products valueForKeyPath:@"@min.launchedOn"]; // June 11, 2012

Object Operators

• @unionOfObjects / @distinctUnionOfObjects: Returns an array of the objects in the property specified in the key path to the right of the operator. @distinctUnionOfObjects removes duplicates, whereas @unionOfObjects does not.

 Example 

[inventory valueForKeyPath:@"@unionOfObjects.name"]; // "iPhone 5", "iPhone 5", "iPhone 5", "iPad Mini", "MacBook Pro", "MacBook Pro"
[inventory valueForKeyPath:@"@distinctUnionOfObjects.name"]; // "iPhone 5", "iPad Mini", "MacBook Pro"

                       
 

iPhone -Get number of lines of UILabel

 First Option :

Firstly calculate height for text according to font :

NSInteger lineCount = 0;
CGSize labelSize = (CGSize){yourLabel.frame.size.width, MAXFLOAT};
CGRect requiredSize = [self boundingRectWithSize:labelSize  options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName: yourLabel.font} context:nil];

Now calculate number of lines :
int charSize = lroundf(yourLabel.font.leading);
int rHeight = lroundf(requiredSize.height);
lineCount = rHeight/charSize;
NSLog(@"No of lines: %i",lineCount);


Second Option :

 NSInteger lineCount = 0;
 CGSize textSize = CGSizeMake(yourLabel.frame.size.width, MAXFLOAT);
 int rHeight = lroundf([yourLabel sizeThatFits:textSize].height)
 int charSize = lroundf(yourLabel.font.leading);
 lineCount = rHeight/charSize;
 NSLog(@"No of lines: %i",lineCount);

iPhone-Number Formatter example

 //Number Formatter example

Ex:1
        NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
        [formatter setNumberStyle:NSNumberFormatterNoStyle];
        [formatter setPositiveFormat:@"$ ##.##"];
         [formatter setLenient:YES];


Ex:2
        NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
        [formatter setNumberStyle:NSNumberFormatterCurrencyStyle];
        [formatter setGeneratesDecimalNumbers:YES];
        [formatter setUsesGroupingSeparator:YES];
        NSString *groupingSeparator = [[NSLocale currentLocale] objectForKey:NSLocaleGroupingSeparator];
        [formatter setGroupingSeparator:groupingSeparator];
        [formatter setGroupingSize:3];

iPhone-Get ScrolllView SubViews using Block

//Get ScrolllView SubViews using Block

if([obj isKindOfClass:[UIButton class]])
{
  UIButton *currentButton = (UIButton *)obj;     NSLog(@"%@",NSStringFromCGRect(currentButton.frame));
}
}];

//Add Dynamic ImageView In ScrollView
