#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

//通过xib/storyboard创建自定义控件会调用此方法，是从xib、storyboard里正在解析且视图全部加载完成之前的时候调用，NSCoder是Xib解析器
- (instancetype)initWithCoder:(NSCoder *)aDecoder {

NSLog(@"%s", __func__);

self = [super initWithCoder:aDecoder];
if (self) {

}
return self;
}

//也是通过xib/storyboard创建自定义控件时调用，不同的是该方法是当所有控件全部加载完成后才调用
- (void)awakeFromNib {

NSLog(@"%s", __func__);
}

- (void)viewDidLoad {
[super viewDidLoad];

NSLog(@"%s", __func__);

}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
