公司為了提高項(xiàng)目的安全性,需要對(duì)目前的項(xiàng)目做一些安全性處理,這么毛玻璃效果就是其中之一.這里做一下代碼的記錄,方便我以后查閱,也歡迎大家提出修改意見(jiàn)!!(崇拜星爺?shù)某绦騿T);
簡(jiǎn)書(shū)代碼咋顯示顏色啊,歡迎評(píng)論區(qū)指導(dǎo)下!!!
先來(lái)張星爺:
代碼如下:
#import "AppDelegate.h"
@interface AppDelegate ()
@property (nonatomic, strong, nullable) UIVisualEffectView *visualEffectView;
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
? ? return YES;
}
- (void)applicationWillResignActive:(UIApplication *)application {
? ? UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
? ? self.visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
? ? self.visualEffectView.alpha = 0;
? ? self.visualEffectView.frame = self.window.frame;
? ? [self.window addSubview:self.visualEffectView];
? ? [UIView animateWithDuration:0.5 animations:^{
? ? ? ? self.visualEffectView.alpha = 1;
? ? }];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
? ? [UIView animateWithDuration:0.5 animations:^{
? ? ? ? self.visualEffectView.alpha = 0;
? ? } completion:^(BOOL finished) {
? ? ? ? [self.visualEffectView removeFromSuperview];
? ? }];
}
@end
