创建九宫格: for (int i = 0; i 4; i++) { int a = 50 + i % 3 * 60 + i % 3 * 20; int b = 50 + i / 3 * 60 + i / 3 * 20; UIButton * bun = [UIButton buttonWithType:UIButtonTypeCustom]; bun.frame = CGRectMake(a, b, 60, 60); bun.backgroundCo
创建九宫格:
for (int i = 0; i < 4; i++) {
int a = 50 + i % 3 * 60 + i % 3 * 20;
int b = 50 + i / 3 * 60 + i / 3 * 20;
UIButton * bun = [UIButton buttonWithType:UIButtonTypeCustom];
bun.frame = CGRectMake(a, b, 60, 60);
bun.backgroundColor = [UIColor redColor];
[self.view addSubview:bun];
}
swift版本:
for i in 0...3 {
print("取余是:\(i%3)")
}
for i in 0...3 {
print("取整是:\(i/3)")
}
控制台打印如下:
