UIDevice属性和NSLog存在问题
|
我一直在尝试使用[[UIDevice currentDevice] ...]和NSLog记录设备参数。尽管尝试不同的方法，但我总是收到相同的警告。
我得到的警告是：
Passing argument 1 of \'NSLog\' from incompatible pointer type
NSString *UDID = [[UIDevice currentDevice] uniqueIdentifier];
NSString *deviceName = [[UIDevice currentDevice] name];
NSString *deviceModel = [[UIDevice currentDevice] model];
NSLog(\"\\nDevice UDID: %@\\nDevice Name: %@\\nDevice Mode:%@\\n\",UDID, deviceName, deviceModel);
NSString *UDID = (NSString*)[[UIDevice currentDevice] uniqueIdentifier];
NSString *deviceName = (NSString*)[[UIDevice currentDevice] name];
NSString *deviceModel = (NSString*)[[UIDevice currentDevice] model];
NSLog(\"\\nDevice UDID: %@\\nDevice Name: %@\\nDevice Mode:%@\\n\",UDID, deviceName, deviceModel);
NSString *UDID = [NSString stringWithFormat:[[UIDevice currentDevice] uniqueIdentifier]];
NSString *deviceName = [NSString stringWithFormat:[[UIDevice currentDevice] name]];
NSString *deviceModel = [NSString stringWithFormat:[[UIDevice currentDevice] model]];
NSLog(\"\\nDevice UDID: %@\\nDevice Name: %@\\nDevice Mode:%@\\n\",UDID, deviceName, deviceModel);
NSLog(\"\\nDevice UDID: %@\\nDevice Name: %@\\nDevice Mode:%@\\n\",[[UIDevice currentDevice] uniqueIdentifier], [[UIDevice currentDevice] name], [[UIDevice currentDevice] model]);

注意字符串开头之前的\'@ \'补蹲农界维
将NSString用作格式字符串，而不是。在字符串前加上。 即：舞备联
需要作为其格式参数。您应该这样呼叫：注意开头的\“ @ \”-这是常量引用。您正在使用裸露的C字符串。
