retain and Copy diff

In a general setting, retaining an object will increase its retain count by one. This will help keep the object in memory and prevent it from being blown away. What this means is that if you only hold a retained version of it, you share that copy with whomever passed it to you.

Copying an object, however you do it, should create another object with duplicate values. Think of this as a clone. You do NOT share the clone with whomever passed it to you.

Convert Char to NsString and vice versa

@selectors in obj-c

elector in Objective C
In short, Selector can either be a name of method or a message to an object when used in the source code. And SEL is the complied form of a Selector.










- (void) fooNoInputs {
NSLog(@"Does selector test");
}

- (void) fooOneInput:(NSString*) first {

// NSLog(@"Does selector test");
NSLog(@"my slectore Logs %@", first);
}

- (void)viewDidLoad
{


//
//##############################################################################

// SELCETOR test

//##############################################################################




[self performSelector:@selector(fooNoInputs)];

[self performSelector:@selector(fooOneInput:) withObject:@"firstc"];













############## difference between

[self playButtonSound]; &

[self performSelector:@selector(playButtonSound)];







Both to the same thing, but [self playButtonSound]; is definitely the normal way to invoke a method in Objective-C. However, using performSelector: allows you to call a method that is only determined at runtime.

@property in objc

Property attributes are special keywords to tell compiler how to generate the getters and setters. Here you specify two property attributes: nonatomic, which tells the compiler not to worry about multithreading, and retain, which tells the compiler to retain the passed-in variable before setting the instance variable.

In other situations, you might want to use the “assign” property attribute instead of retain, which tells the compiler NOT to retain the passed-in variable. Or perhaps the “copy” property attribute, which makes a copy of the passed-in variable before setting.

Categories in obj-c

// Base Class
@interface ClassA : NSObject
- (NSString *) myMethod;
@end
@implementation ClassA
- (NSString*) myMethod { return @"A"; }
@end

//Category
@interface ClassA (CategoryB)
- (NSString *) myMethod;
@end
@implementation ClassA (CategoryB)
- (NSString*) myMethod { return @"B"; }
@end



Calling the method "myMethod" after including the category nets the result "B".

Objective-C program with multiple parameter



Objective-C enables programmer to use method with multiple parameter. These parameter can be of same type or of different type.
This is a sample program that shows sum of three numbers as output.

Difference betwen protocol and category

A protocol is the same thing as an interface in Java: it's essentially a contract that says, "Any class that implements this protocol will also implement these methods."

A category, on the other hand, just binds methods to a class. For example, in Cocoa, I can create a category for NSObject that will allow me to add methods to the NSObject class (and, of course, all subclasses), even though I don't really have access to NSObject.

To summarize: a protocol specifies what methods a class will implement; a category adds methods to an existing class.

The proper use of each, then, should be clear: Use protocols to declare a set of methods that a class must implement, and use categories to add methods to an existing class.

if a is a struct use a.b

if a is a pointer to a struct use a->b

if a is an object pointer and b is a ivar use a->b

JS to Obj-c and Objc to JS

search for text which you can to test against

- (BOOL)webView:(UIWebView *)localwebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {

NSURL *url = [request URL];

NSString *path = [[request URL] path];

NSString *pathTrimmed = [path lastPathComponent];

if ([pathTrimmed isEqualToString:@"Reset"]) {

// Display alert
UIAlertView *alertb = [[UIAlertView alloc] initWithTitle:@"You want to Reset Data??" message:@"" delegate:self cancelButtonTitle:@"No" otherButtonTitles: @"YES",nil];
alertb.tag=3;
[alertb show];

[alertb release];
return NO;
}
return YES;


}




and then based on alert call JS Function defined in html page


- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {


if(buttonIndex == 1) {

//NSLog(@" its done now uplaod data");
[localwebView stringByEvaluatingJavaScriptFromString:@"confirmation()"];
