1.UITouch

#import "ViewController_0.h"

@interface ViewController_0 ()

@property (nonatomic, strong)UILabel *label;

@end

@implementation ViewController_0

- (void)viewDidLoad {
  
  [super viewDidLoad];
  
  self.label          = [[UILabel alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
  self.label.backgroundColor  = [UIColor yellowColor];
  self.label.layer.borderWidth = 1;
  [self.view addSubview:self.label];
  
  UILabel *textlabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 80, 200, 45)];
  textlabel.text   = @"拖动方块";
  [textlabel sizeToFit];
  textlabel.font   = [UIFont systemFontOfSize:12];
  [self.view addSubview:textlabel];
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event {

  //1.拿到手势
  UITouch *touch = [touches anyObject];
  
  //2.拿到touch 所在view的坐标
  CGPoint point = [touch locationInView:self.view];
  
  //3.让label拿到坐标
  self.label.center = point;
  
  NSLog(@"1.手指接触到了屏幕");
}

- (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event {

  //1.拿到手势

  //3.让label拿到坐标
  self.label.center = point;
  
  NSLog(@"2.手指在屏幕上移动");
}
