創(chuàng)建三個按鈕
// 按鈕1
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setTitle:@"檢測站點(diǎn)是否可連接" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(didClick) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
// 按鈕2
UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn1.frame = CGRectMake(100, 300, 300, 30);
[btn1 setTitle:@"檢測234G是否可連接" forState:UIControlStateNormal];
[btn1 addTarget:self action:@selector(didClick234G) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn1];
// 按鈕3
UIButton *btn3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn3.frame = CGRectMake(100, 400, 300, 30);
[btn3 setTitle:@"檢測wifi是否可連接" forState:UIControlStateNormal];
[btn3 addTarget:self action:@selector(didClickwifi) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn3];
