IOS总结_IOS经常使用的方法集合、调用系统电话、设备区分、APP内永不锁屏

调用系统打电话的功能

打电话功能仅仅有iPhone支持，对于其它设备相应button应该禁用。

//直接调用系统电话呼叫功能，挂断电话后不能回到应用程序

［UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8004664411"］;   


//调用系统电话呼叫功能前要给出提示，挂断电话后能回到应用程序

［UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://8004664411"］;   


//同理，也能够调用系统的地图，短信等功能

openURL能帮助你执行Maps，SMS，Browser,Phone甚至其它的应用程序。这是Iphone开发中我常常须要用到的一段代码，它只唯独一行而已。


区分设备类型的方法

//推断是iPhone还是iPad
 用[UIDevice currentDevice].model，这个返回的是一个NSString，你能够做例如以下推断就能知道设备是iPad还是iPhone.

if (［UIDevice currentDevice].model rangeOfString:@"iPad"].location != NSNotFound) 

     NSLog(@"This is an iPad!"); 


用UI_USER_INTERFACE_IDIOM()方法，这是系统定义的一条宏。用法也非常easy。

if (UI_USER_INTERFACE_IDIOM() ＝＝ UIUserInterfaceIdiomPad) 

     NSLog(@"This is an iPad!"); 


推断设备类型和型号

- (NSString*) doDevicePlatform
{
    size_t size;
    int nR = sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = (char *)malloc(size);
    nR = sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
    free(machine);
    
    if ([platform isEqualToString:@"iPhone1,1"]) {
        
        platform = @"iPhone";
        
    } else if ([platform isEqualToString:@"iPhone1,2"]) {
        
        platform = @"iPhone 3G";
        
    } else if ([platform isEqualToString:@"iPhone2,1"]) {
        
        platform = @"iPhone 3GS";
        
    } else if ([platform isEqualToString:@"iPhone3,1"]||[platform isEqualToString:@"iPhone3,2"]||[platform isEqualToString:@"iPhone3,3"]) {
        
        platform = @"iPhone 4";
        
    } else if ([platform isEqualToString:@"iPhone4,1"]) {
        
        platform = @"iPhone 4S";
        
    } else if ([platform isEqualToString:@"iPhone5,1"]||[platform isEqualToString:@"iPhone5,2"]) {
        
        platform = @"iPhone 5";
        
    }else if ([platform isEqualToString:@"iPhone5,3"]||[platform isEqualToString:@"iPhone5,4"]) {
        
        platform = @"iPhone 5C";
        
    }else if ([platform isEqualToString:@"iPhone6,2"]||[platform isEqualToString:@"iPhone6,1"]) {
        
        platform = @"iPhone 5S";
        
    }else if ([platform isEqualToString:@"iPod4,1"]) {
        
        platform = @"iPod touch 4";
        
    }else if ([platform isEqualToString:@"iPod5,1"]) {
        
        platform = @"iPod touch 5";
        
    }else if ([platform isEqualToString:@"iPod3,1"]) {
        
        platform = @"iPod touch 3";
        
    }else if ([platform isEqualToString:@"iPod2,1"]) {
        
        platform = @"iPod touch 2";
        
    }else if ([platform isEqualToString:@"iPod1,1"]) {
        
        platform = @"iPod touch";
        
    } else if ([platform isEqualToString:@"iPad3,2"]||[platform isEqualToString:@"iPad3,1"]) {
        
        platform = @"iPad 3";
        
    } else if ([platform isEqualToString:@"iPad2,2"]||[platform isEqualToString:@"iPad2,1"]||[platform isEqualToString:@"iPad2,3"]||[platform isEqualToString:@"iPad2,4"]) {
        
        platform = @"iPad 2";
        
    }else if ([platform isEqualToString:@"iPad1,1"]) {
        
        platform = @"iPad 1";
        
    }else if ([platform isEqualToString:@"iPad2,5"]||[platform isEqualToString:@"iPad2,6"]||[platform isEqualToString:@"iPad2,7"]) {
        
        platform = @"ipad mini";
        
    } else if ([platform isEqualToString:@"iPad3,3"]||[platform isEqualToString:@"iPad3,4"]||[platform isEqualToString:@"iPad3,5"]||[platform isEqualToString:@"iPad3,6"]) {
        
        platform = @"ipad 3";
        
    }
    
    return platform;
}


当设备在执行程序时永不锁屏

[[UIApplicationsharedApplication]setIdleTimerDisabled:YES];


兴许更新...
