取消某个页面的侧滑返回页面

直接自定义设置返回按钮就好了，不要用默认的返回按钮。

//btn_back

self.navigationItem.leftBarButtonItem= [[UIBarButtonItemalloc]initWithImage:[UIImageimageNamed:@"btn_back"]style:UIBarButtonItemStylePlaintarget:selfaction:@selector(showMessage)];

//返回提示信息

-(void)showMessage{

[UIAlertViewalertWithCallBackBlock:^(NSIntegerbuttonIndex) {

if(buttonIndex ==1) {

[self.navigationControllerpopViewControllerAnimated:YES];

}

}title:@"提示"message:@"确定要放弃本次发布吗"cancelButtonName:@"取消"otherButtonTitles:@"确定",nil];

}
