ios nsdata怎么转int

Answer 1

正确的转换方法。

int i = 1;
NSData *data = [NSData dataWithBytes: &i length: sizeof(i)];

int i;
[data getBytes: &i length: sizeof(i)];

Answer 2

NSData *data = [NSData data];

NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

int *num = [str intValue];
先转为字符串，在将字符串转为int类型。这比较好理解
