做自定义键盘，首先要适配所有的设备，所以在这里就要知道用户使用的是哪一款手机，下面总结了几种获取设备型号的方法；
PS：这些也是我在网上自己找的，以防不时之需。
方法一：
1 //***宏定义 2 /*[UIScreen instancesRespondToSelector:@selector(currentMode)]; 3 判断UIScreen 类中是否包含currentMode这个方法， 4 若存在则调用CGSizeEqualToSize比较2个size大小是否相同， 5 若相同返回yes，否则返回no。 6 */ 7 #define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO) 8 然后： 9 if（iPhone5）{ 10 //***具体操作 11 }else{ 12 13 //***具体操作 14 15 }
方法二：
1 #define Screen_height [[UIScreen mainScreen] bounds].size.height 2 #define Screen_width [[UIScreen mainScreen] bounds].size.width
方法三：
PS：注意，需要#import "sys/utsname.h"
1 + (NSString*)deviceString 2 { 3 // 需要#import "sys/utsname.h" 4 struct utsname systemInfo; 5 uname(&systemInfo); 6 NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; 7 8 if ([deviceString isEqualToString:@"iPhone1,1"]) return @"iPhone 1G"; 9 if ([deviceString isEqualToString:@"iPhone1,2"]) return @"iPhone 3G"; 10 if ([deviceString isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS"; 11 if ([deviceString isEqualToString:@"iPhone3,1"]) return @"iPhone 4"; 12 if ([deviceString isEqualToString:@"iPhone4,1"]) return @"iPhone 4S"; 13 if ([deviceString isEqualToString:@"iPhone5,2"]) return @"iPhone 5"; 14 if ([deviceString isEqualToString:@"iPhone3,2"]) return @"Verizon iPhone 4"; 15 if ([deviceString isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G"; 16 if ([deviceString isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G"; 17 if ([deviceString isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G"; 18 if ([deviceString isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G"; 19 if ([deviceString isEqualToString:@"iPad1,1"]) return @"iPad"; 20 if ([deviceString isEqualToString:@"iPad2,1"]) return @"iPad 2 (WiFi)"; 21 if ([deviceString isEqualToString:@"iPad2,2"]) return @"iPad 2 (GSM)"; 22 if ([deviceString isEqualToString:@"iPad2,3"]) return @"iPad 2 (CDMA)"; 23 if ([deviceString isEqualToString:@"i386"]) return @"Simulator"; 24 if ([deviceString isEqualToString:@"x86_64"]) return @"Simulator"; 25 NSLog(@"NOTE: Unknown device type: %@", deviceString); 26 return deviceString; 27 }
1 + (NSString*)deviceString 2 2 { 3 3 // 需要#import "sys/utsname.h" 4 4 struct utsname systemInfo; 5 5 uname(&systemInfo); 6 6 NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; 7 7 8 8 if ([deviceString isEqualToString:@"iPhone1,1"]) return @"iPhone 1G"; 9 9 if ([deviceString isEqualToString:@"iPhone1,2"]) return @"iPhone 3G"; 10 10 if ([deviceString isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS"; 11 11 if ([deviceString isEqualToString:@"iPhone3,1"]) return @"iPhone 4"; 12 12 if ([deviceString isEqualToString:@"iPhone4,1"]) return @"iPhone 4S"; 13 13 if ([deviceString isEqualToString:@"iPhone5,2"]) return @"iPhone 5"; 14 14 if ([deviceString isEqualToString:@"iPhone3,2"]) return @"Verizon iPhone 4"; 15 15 if ([deviceString isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G"; 16 16 if ([deviceString isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G"; 17 17 if ([deviceString isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G"; 18 18 if ([deviceString isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G"; 19 19 if ([deviceString isEqualToString:@"iPad1,1"]) return @"iPad"; 20 20 if ([deviceString isEqualToString:@"iPad2,1"]) return @"iPad 2 (WiFi)"; 21 21 if ([deviceString isEqualToString:@"iPad2,2"]) return @"iPad 2 (GSM)"; 22 22 if ([deviceString isEqualToString:@"iPad2,3"]) return @"iPad 2 (CDMA)"; 23 23 if ([deviceString isEqualToString:@"i386"]) return @"Simulator"; 24 24 if ([deviceString isEqualToString:@"x86_64"]) return @"Simulator"; 25 25 NSLog(@"NOTE: Unknown device type: %@", deviceString); 26 26 return deviceString; 27 27 }
