㈠ 宏定义怎样得到ios的系统版本
获得IOS系统版本号 [[[UIDevice currentDevice] systemVersion] floatValue]获得硬件名称+ (NSString*)getMachine{ size_t size; sysctlbyname("hw.machine", NULL, &size, NULL, 0); char *name = malloc(size); sysctlbyname("hw.machine", name, &size, NULL, 0); NSString *machine = [NSString stringWithCString:name encoding:NSUTF8StringEncoding]; free(name); if( [machine isEqualToString:@"i386"] || [machine isEqualToString:@"x86_64"] ) machine = @"ios_Simulator"; else if( [machine isEqualToString:@"iPhone1,1"] ) machine = @"iPhone_1G"; else if( [machine isEqualToString:@"iPhone1,2"] ) machine = @"iPhone_3G"; else if( [machine isEqualToString:@"iPhone2,1"] ) machine = @"iPhone_3GS"; else if( [machine isEqualToString:@"iPhone3,1"] ) machine = @"iPhone_4"; else if( [machine isEqualToString:@"iPod1,1"] ) machine = @"iPod_Touch_1G"; else if( [machine isEqualToString:@"iPod2,1"] ) machine = @"iPod_Touch_2G"; else if( [machine isEqualToString:@"iPod3,1"] ) machine = @"iPod_Touch_3G"; else if( [machine isEqualToString:@"iPod4,1"] ) machine = @"iPod_Touch_4G"; else if( [machine isEqualToString:@"iPad1,1"] ) machine = @"iPad_1"; else if( [machine isEqualToString:@"iPad2,1"] ) machine = @"iPad_2"; return machine;}
㈡ ios swift怎么使用oc的宏
如果没c语言基础就直接搞swift吧，swift把oc中一些比较麻烦的东西进行了改进。比如字符串的赋值，oc中分引用赋值和显式，初学者很可能会乱用导致bug，swift里统一了，所有字符串赋值都是一个出来。还有各种mutable和immutable的类，oc中采用在类名前面加个Mutable来区分，当初第一次用NSArray的时候硬是找不到Add方法，原来在NSMutableArray里。Swift里用let和var两个关键字就把它们区分出来了，更自然，还少打字。然后Swift还支持范型，不需要像oc那样，从集合里挑个NSObject出来再强制转换。
㈢ IOS或者安卓系统的手机，什么软件可以运行EXCEL宏
2017年老版的可以的，就是找不到
