Hello, I am the beginner in Xcode, and have little SVRT to understand the syntax of Xcode, hope someone out there can dr help me. No you should make use of this: [btnSend setTitle: @ "Test"]; vs. btnSend.titleLabel.text = @ "Test"; Male for the forward different methods depending on which way you call them? Can someone explain and Tex cf. them with C # code so I can make this fr Once sake. I get the option to television in .NET C # is written: btnSend.Text = "test"; but how to write an alternative?
Hello, resting heart rate I am the beginner in Xcode, and have little SVRT to understand the syntax of Xcode, hope someone out there can dr help me. No you should make use of this: [btnSend setTitle: @ "Test"]; vs. btnSend.titleLabel.text = @ "Test"; Male for the forward different resting heart rate methods depending resting heart rate on which way you call them? Can someone explain and Tex cf. them with C # code so I can make this fr Once sake. I get the option to television in .NET C # is written: btnSend.Text = "test"; but how to write an alternative? Was quite long ago, I fiddled with Objective-C now but can frska explain a little just because bright gray s r syntax of Objective-C and has nothing to do with Xcode itself to g ra. This: [btnSend setTitle: @ "Test"]; Calls the setTitle resting heart rate p btnSend and sends the strngen @ "Test". The method is a "setter" method as allts puts title The value. Previously this was only way to make this p but p recently (since 2.0 I think) have dot-notation come in Objective-C. It is just "syntactic sugar" for the same thing. I think empty. the compiler gr of dot notation to [] -notation at compile It is perhaps a little rrigt No one can use the syntax, resting heart rate for sometimes you have no choice but are required to make use of []. Methods without parameters _kan_ man calling with dot notation (however kiosks p if it is "best practice"): foo.barMethod If you have parameters p are required to make use of you [] syntax:
Code: foo.barMethod: @ "Hello" <- Error! [Foo barMethod: resting heart rate @ "Hello"] resting heart rate <- Rtt! In addition, define the Objective-C parameters in the method name's on the method takes several attributes you are required to use the []
Code: foo.barMethod: @ "Hello" withBaz: @ "World" <- Works of course not .... [foo barMethod: @ "Hello" resting heart rate withBaz: @ "World"] <- Does It fire- shared meaning of the dot syntax, some like and others hate. Many think the dot syntax is unclear d can not really see what you are accessing. Ex: int a = foo.bar r wore a method that makes a lot more than to return a value or is it an attribute you hmtar directly? int a = [foo bar] Here we see that we are calling a method ("send a message" that it says in Objective-C). D, we know there is a method that might otherwise gr n will only return an int. Some says that _bara_ should make use dot syntax to properties and other says otherwise ... Lste little about it and it is quite rrigt ... Ngon else can safe explain more sense Mainly's it is just "syntactic sugar" anyway! resting heart rate Here's some more info anyway: http://blog.bignerdranch.com/83-83/ Edit: [btnSend setTitle: @ "Test"]; is equivalent to: btnSend.setTitle ("Test") in C # __________________ SvenskaAckord.se - Chords and tablature! - Accessible Developer - Ruby / Rails etc. - linuspettersson.net
