Create multiple threads for iosGCD

Create multiple threads for iosGCD

Oh, try to split it into a section. This makes it hard for everyone to see clearly. I have three ways to create a thread. The Code is as follows:

 

 

# Import "ViewController. h"

 

@ Interface ViewController ()

 

@ End

 

@ Implementation ViewController

 

-(Void) viewDidLoad {

[Super viewDidLoad];

}

// When the user clicks the screen, the execution thread

-(Void) touchesBegan :( NSSet *) touches withEvent :( UIEvent *) event

{

[Self testThread];

}

 

-(Void) testThread

{

 

// Obtain the current thread, which is the main thread.

NSThread * curThread = [NSThread currentThread];

NSLog (@ "curThread = % @", curThread );

 

//// Method for obtaining the master thread

// NSThread * mainThread = [NSThread mainThread];

// NSLog (@ "mainThread = % @", mainThread );

//

 

[Self createThread1];

 

}

 

 

-(Void) createThread1

{

// An NSThread object is a thread

// Parameter 1 and 2: Specify parameter 1 in the thread to call the method of parameter 2

// Parameter 3: pass real parameters to the method specified by parameter 2

NSThread * thread = [[NSThread alloc] initWithTarget: self selector: @ selector (threadMain :) object: @ "thread creation method 1"];

 

[Thread setName: @ "My name is egg"];

[Thread start];

}

-(Void) createThread2

{

 

[NSThread detachNewThreadSelector: @ selector (threadMain :) toTarget: self withObject: @ "thread creation method 2"];

 

 

}

-(Void) createThread3

{

 

 

[Self defined mselectorinbackground: @ selector (threadMain :) withObject: @ "thread creation method 3"];

}

-(Void) threadMain :( id) obj

{

For (int I = 0; I <1000; I ++ ){

NSLog (@ "I = % d, obj = % @, thread = % @", I, obj, [NSThread currentThread]);

}

 

 

}

Of course, you still need to use more features, just like eating more food. You can pick up the thorns and continue the next article. Haha
