When should I initialize a view controller using initWithNibName?

http://stackoverflow.com/questions/2224077/when-should-i-initialize-a-view-controller-using-initwithnibname

this is incorrect. It puts implementation details the name of the NIB and the fact that a NIB is even used into the caller. That breaks encapsulation. The correct way to do this is MYViewController vc MYViewController alloc init Then in MYViewController.. NO @ Initialize with init return nil This moves the key implementation details back into the object and prevents callers from accidentally breaking encapsulation. Now if you change the name of the NIB or move to programmatic construction you..

Understanding reference counting with Cocoa and Objective-C

http://stackoverflow.com/questions/6578/understanding-reference-counting-with-cocoa-and-objective-c

s NSString alloc initWithString @ Hello World Now what We want to return s but we've upped its reference count. The caller shouldn't be responsible for releasing it since we're the ones that created it. If we call release however the reference.. that created it. If we call release however the reference count will hit zero and bad memory will be returned to the caller. The answer is to call autorelease before returning the string. By explicitly calling autorelease we pass the responsibility.. which will happen at some later time. The consequence is that the returned string will still be valid for the caller of this function. return s autorelease I realize all of this is a bit confusing at some point though it will click. Here..

How can I launch back the app that opened my custom URL scheme?

http://stackoverflow.com/questions/9022967/how-can-i-launch-back-the-app-that-opened-my-custom-url-scheme

Parse the URL NSString hostString launchURL host blah blah blah... It works very nice but I need to launch the caller application i.e. the app that opened the URL . So my question here is is it possible I have been playing with UIApplicationLaunchOptionsSourceApplicationKey.. improve this question The only way would be to have both apps each support a custom URL scheme. Then you embed the caller URL in the URL of the other app. For example let's say App2 wants to call App1 in a way so that App1 could then call back.. wants to call App1 in a way so that App1 could then call back to App2. It would create and open an URL like this app1 caller app2 3A 2F 2Fblabla When you decode the caller part you would get back the string app2 blabla which you could then again..
