判斷設備是否是 iphone5

編輯:關於IOS

1.在程序中涉及到全屏的寬高的時候,初始化的時候,代碼中不要寫320和480

#define Screen_height   [[UIScreen mainScreen] bounds].size.height #define Screen_width    [[UIScreen mainScreen] bounds].size.width    2.使用宏定義方法判斷 #define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO) if(iPhone5){     /*代碼操作*/ }else{     /*代碼操作*/ } 在網上又找到另外一種方法: + (NSString*)deviceString   {       // 需要#import "sys/utsname.h"       struct utsname systemInfo;       uname(&systemInfo);       NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];               if ([deviceString isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";       if ([deviceString isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";       if ([deviceString isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";       if ([deviceString isEqualToString:@"iPhone3,1"])    return @"iPhone 4";       if ([deviceString isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";       if ([deviceString isEqualToString:@"iPhone5,2"])    return @"iPhone 5";       if ([deviceString isEqualToString:@"iPhone3,2"])    return @"Verizon iPhone 4";       if ([deviceString isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";       if ([deviceString isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";       if ([deviceString isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";       if ([deviceString isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";       if ([deviceString isEqualToString:@"iPad1,1"])      return @"iPad";       if ([deviceString isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";       if ([deviceString isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";       if ([deviceString isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";       if ([deviceString isEqualToString:@"i386"])         return @"Simulator";       if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";       NSLog(@"NOTE: Unknown device type: %@", deviceString);       return deviceString;   }
