Split NSArray based on characters

By AP, 

            
Arrays are omnipresent. As I needed a snippet to make a string into an array of values, I thought would be helpful to share this for beginners.


For example, take a string variable like,


NSString *str = [[NSString alloc] initWithFormat:@"This##is##string##conversion##example"];



Create an array variable “array1” as:-


NSArray *array1 = [[NSArray alloc] initWithArray:[str componentsSeparatedByString:@"##"]];
for (int i=0;i<array1.count; i++) {
   NSLog(@"place name at index %d: %@\n", i, [array1 objectAtIndex:i]);
}



I used the for loop to know the array1 values, which is displayed in Console output:


2013-10-17 01:26:12.335 PickerViewTest[21740:a0b] place name at index 0: This
2013-10-17 01:26:12.337 PickerViewTest[21740:a0b] place name at index 1: is
2013-10-17 01:26:12.337 PickerViewTest[21740:a0b] place name at index 2: string
2013-10-17 01:26:12.338 PickerViewTest[21740:a0b] place name at index 3: conversion
2013-10-17 01:26:12.338 PickerViewTest[21740:a0b] place name at index 4: example



Hope it helps.

                


    





    
    

                        

                    

                        

                            
Bootable USB Drive with OS X Mavericks — Fastest Way
By AP,  
Apple released its latest OS X version, 10.9 or “Mavericks”. Quote Apple: “With more than 200 new features, OS X Mavericks brings Maps and iBooks to the Mac, introduces Finder Tabs and Tags, enhances multi-display support and includes an all-new version of Safari.” Cool, ain’t it ? But this I like most: “The latest release […]


                            

                                
                                                                    
                            

                        

                    

                

                        

                    

                        

                            
iOS 7 UIPickerView Simple Application
By AP,  
Recently I was asked by a friend to provide some support with UIPickerView in iOS 7. He was a bit puzzled by what it seemed to be the impossibility to pad the content of each picker view row to a certain distance from the left side of the UIPickerView. Basically, let’s consider the following example. […]

Before we continue the second installment in the series of basic tutorials about UIPickerView usage and customization, a short digression. Most Cocoa/ Cocoa Touch tutorials assume that all connections to delegates, data sources and outlets are done visually in XCode. Our previous example was no exception. You can see from the project (gave the link below) […]

Going into some USB programming for a project I am into (on my Mac), I ran into this and I thought would be nice and useful to elaborate a bit. This is about void* pointers and callbacks in C. USB device discovery and probing under IOKit makes heavy use of callbacks, I wanted to write […]

NSString initWithBytes:length:encoding instance method. A quick example. Uses a NSData object from the content of my blog’s first page and displays the string in an NSTextView outlet: – (void)awakeFromNib { ALATest(); myURL = [NSURL URLWithString:@"https://www.alauda.ro"]; myData = [NSData dataWithContentsOfURL:myURL]; myString = [[NSString alloc] initWithBytes:[myData bytes] length:[myData length] encoding:NSASCIIStringEncoding]; #ifdef DEBUG NSLog(@"Data is: %@", myString); #endif […]

Ok, this will be a short one. Probably I will create a category like “code snippets and hints” to include all these small articles. This is about zombies in your coding projects and how to chase them. Enabling a project to trace zombies is different in XCode 4 than in previous versions. There is a […]

Some good months ago I started a series on NSOutlineView that I didn’t imagine it will stir such an interest. To my astonishment, googling NSOutlineView ranks my post fourth in the search, immediately after Apple’s official documentation and some other two links: This intriguing situation (nevertheless inspiring for me) might have to do with the […]

…and not only software (maybe). OK, to keep things short, I got tired by limitations of my Saleae logic analyzer, especially on the software side so I decided to build one. This is my new project: a DIY logic analyzer that I will hopefully use to better extent in my other projects. First results promising. […]
