如何使用 x 轴值对数组元素进行排序？

Question

Actually I am getting the label values and x-coordinate and I need to sort the label values according to x-coordinate values. Can you please any one give me code how to do it. Thanks in advance..

This is one way to do it, you should be able to do it with keypaths a lot nicer.

[labels sortUsingComparator:^NSComparisonResult(id obj1, id obj2) {
    return [[NSNumber numberWithFloat:[(UIView *)obj1 frame].origin.x] compare:[NSNumber numberWithFloat:[(UIView *)obj2 frame].origin.x]];
}];
