那些年踩过的坑/知识点积累

iOS-解决tabBar跳动问题

[[UITabBar appearance] setTranslucent:NO];

光标颜色修改

 search.tintColor = [UIColor redColor];
textFiled.tinColor = [UIColor  orangeColor];

1，适配齐刘海，填充顶部空白

 if (@available(iOS 11.0, *)) {
        mainScrollow.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
        NSLog(@"11.0f");
    } else {
        //        self.automaticallyAdjustsScrollViewInsets = NO;
        NSLog(@"10f");
    }

2，判断以某串字符开头或结尾

[resourcesFile.name hasPrefix:@"AAA"];//判断是否是“AAA”开头
[resourcesFile.name hasSuffix:@".prss"];//判断是否是“.prss”结尾

3，判断数子是否为nan或INF

if (isnan(a)) {
       NSLog(@"NaN");
   }
   if (isinf(b)) {
       NSLog(@"+inf");
   }

4,模拟器路径

/应用程序/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

5，数字带点的键盘
