获取“安全区”：屏幕快照 2018-09-12 1、在iphoneX及以后的⼿机适配：状态栏和底栏// top = 20,默认UIEdgeInsets insets = UIEdgeInsetsMake(20, 0, 0, 0); if (@available(ios 11.0, *)) {// insets = eaInsets; // 在viewDidLoad ⽅法中获取不到 safeAreaInsets insets = [UIApplication sharedApplication].eaInsets; }NSLog(@"top = %.2f n bottom = %.2f", , );输出：(lldb) po 48(lldb) po 34附⾔：设置弹窗：AppDelegate *appdelegate = (AppDelegate *)[UIApplication sharedApplication].delegate; _chapterView = [[LBRChapterView alloc] initWithFrame:]; _ilModel = ilModel; [ addSubview:rView];2、设置UIView的⼏个圆⾓：(最好不要使⽤Masonry⾃动布局，masonry已经设置NO了，这个属性设置为no后，设置frame就没作⽤了)masonry已经设置NO了，这个属性设置为no后，设置frame就没作⽤了.jpeg _tipsView = [[UIView alloc] init]; _oundColor = RGBA(67, 196, 148, 1); _ = CGRectMake(0, 100, [UIScreen mainScreen]./375*100, [UIScreen mainScreen]./375*22);// oBounds = YES;// Radius = [UIScreen mainScreen]./375*22/2; [ew addSubview:ew];// [ew makeConstraints:^(MASConstraintMaker *make) {// _equalTo(_bottom).offset([UIScreen mainScreen]./375*20);// _equalTo(_left);// _equalTo([UIScreen mainScreen]./375*100);// _equalTo([UIScreen mainScreen]./375*22);// }];
