简单的代码..
视图控制器.h
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
- (IBAction)dragout:(id)sender;
@end
视图控制器.m
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)dragout:(id)sender {
NSLog(@"-----");
}
@end
在情节提要中,有 1 个按钮,其大小适合文本“按钮”。将“发送事件:触摸外部”链接到“dragout”IBAction。
当我触摸按钮内部并将手指拖到按钮外部时,我需要移动超过按钮大小才能调用“dragout”IBAction。近 3 倍的宽度和高度尺寸。为什么会这样?谢谢阅读。
