废话不多说，咱直接开始。
Part1
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
//这是一枚可变的icon
UIMutableApplicationShortcutItem *shortItem1 = [[UIMutableApplicationShortcutItem alloc] initWithType:@"1" localizedTitle:@"对！没错！"];
//这是icon的图片，对图片有要求哦，不符合规则显示不来哦
UIApplicationShortcutIcon *icon1 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"Image1"];
//给icon设置一下图片
shortItem1.icon = icon1;
UIMutableApplicationShortcutItem *shortItem2 = [[UIMutableApplicationShortcutItem alloc] initWithType:@"2" localizedTitle:@"我就是"];
UIApplicationShortcutIcon *icon2 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"Image2"];
shortItem2.icon = icon2;
UIMutableApplicationShortcutItem *shortItem3 = [[UIMutableApplicationShortcutItem alloc] initWithType:@"3" localizedTitle:@"一台完美的"];
UIApplicationShortcutIcon *icon3 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"Image3"];
shortItem3.icon = icon3;
UIMutableApplicationShortcutItem *shortItem4 = [[UIMutableApplicationShortcutItem alloc] initWithType:@"4" localizedTitle:[PhoneInfoManager getCurrentDeviceModel]];
UIApplicationShortcutIcon *icon4 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"Image4"];
shortItem4.icon = icon4;
NSArray *shortItems = [[NSArray alloc] initWithObjects:shortItem4, shortItem3, shortItem2, shortItem1, nil];
NSLog(@"%@", shortItems);
[[UIApplication sharedApplication] setShortcutItems:shortItems];
return YES;
}
这就是效果！
在AppDelegate里边实现这一段代码就可以响应点击的icon的事件（可以根据shortcutItem.type判断哪个icon）
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler{
//很普通的一枚Alert（Xcode7废弃了UIAlertVIew好不习惯啊）
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"讨厌，你又点了人家" message:@"你要对我负责！！！" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"我会的" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"我一定会的" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alertController addAction:cancelAction];
[alertController addAction:okAction];
[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:alertController animated:YES completion:nil];
}
Part2
接下来就是稍微比较复杂的用3DTouch控制ViewController等UI。
轻按效果图
重按效果图
咱们先去你想要实现3DTouch的类里注册实现UIViewControllerPreviewingDelegate
@interface ViewController ()<UIViewControllerPreviewingDelegate>
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
/**
* 如果支持3DTouch，就添加3DTouch的代理
*/
if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
[self registerForPreviewingWithDelegate:self sourceView:self.view];
}
_lbl.text = [NSString stringWithFormat:@"****妈妈再也不用担心我装逼了****\n\n我的设备: %@\n\n我的内存: %.2f MB\n\n我的储空间: %qi GB\n\n********************************",[PhoneInfoManager getCurrentDeviceModel],[PhoneInfoManager logMemoryInfo],[PhoneInfoManager freeDiskSpaceInBytes]];
}
然后使劲按，就会触发到事件
- (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)context viewControllerForLocation:(CGPoint) point
{
/**
轻按
- returns: 要显示的VC
*/
BaseViewController *vc = [[BaseViewController alloc] init];
vc.view.frame = self.view.frame;
UILabel *lbl = [[UILabel alloc]initWithFrame:vc.view.frame];
lbl.textColor = [UIColor whiteColor];
lbl.textAlignment = NSTextAlignmentCenter;
lbl.numberOfLines = 0;
lbl.font = [UIFont systemFontOfSize:50.0];
lbl.text = [NSString stringWithFormat:@"不要这么使劲的戳人家嘛\n\n⁄(⁄ ⁄•⁄ω⁄•⁄ ⁄)⁄\n\n淫家只是一台可以摸的iPhone了啦"];
vc.view = lbl;
/**
* 轻按显示VC大小范围
*
* @param 0.0f 显示宽度(0为不限制？)
* @param 450.0f 显示高度
*
* @return vc
*/
vc.preferredContentSize = CGSizeMake(0.0f,300.0f);
/**
* 触摸和轻按中间的过度模糊层（rect为0就没有这个效果啦！！！系统会去掉，设为float最小值会全覆盖）
*
* @param CGFLOAT_MIN float最小值
* @param CGFLOAT_MIN float最小值
* @param CGFLOAT_MIN float最小值
* @param CGFLOAT_MIN float最小值
*
* @return 感觉像没用
*/
CGRect rect = CGRectMake(CGFLOAT_MIN, CGFLOAT_MIN, CGFLOAT_MIN ,CGFLOAT_MIN);
context.sourceRect = rect;
return vc;
}
-(void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit{
/**
* 重按push进去，然后3秒后移除
*/
[self showViewController:viewControllerToCommit sender:self];
double delayInSeconds = 3.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
[viewControllerToCommit dismissViewControllerAnimated:YES completion:^{
}];
});
}
然后你就会问了，呢个BaseViewController是干吗用的，因为3DTouch轻按时候上拉事件，必须重写将要弹出ViewController的一个方法。
轻按上划触发事件效果图
#import "BaseViewController.h"
@interface BaseViewController ()<UIViewControllerPreviewingDelegate>
@end
@implementation BaseViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
//预览页面 底部Action Items
- (NSArray<id<UIPreviewActionItem>> *)previewActionItems{
UIPreviewAction *p1 =[UIPreviewAction actionWithTitle:@"不要酱紫" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
}];
UIPreviewAction *p2 =[UIPreviewAction actionWithTitle:@"好了啦" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
}];
NSArray *actions = @[p1,p2];
return actions;
}
