Question

尝试用uarmageviews的nsarray创建一个for循环，但似乎无法让cgrectmake工作。

Location = CGRectMake(10, 10, 97, 110);
NSArray *cardImages = [[NSArray alloc]initWithObjects:car1,car2,card3,car4,car5,car6,car7,car8,car9,car10,car11, nil];
for (UIImageView *image in cardImages) {

    image.frame = Location;
    image.image = [UIImage imageNamed:@"ace.png"];
}

Answer 1

在您当前的代码中，您要为所有UIImageView设置相同的框架。尝试每次迭代更改帧原点：

NSArray *cardImages = @[ card1, card2, card3, card4, card5, card6, card7, card8, card9, card10,card11 ];
for (int i = 0; i < [cardImages count]; i++) {
    UIImageView *image = cardImages[i];

    // Each iteration new frame will have bigger x position (0, 10, 20...)
    image.frame = CGRectMake(10 * i, 10, 97, 110);
    image.image = [UIImage imageNamed:@"ace.png"];
}

如何在nsarray循环中使用cgrect
