Check UIImageView array frame equality with NSTimer

由 大憨熊 提交于 2019-12-11 23:46:44
问题 I am wondering how to check if all the frames of two UIImageView NSMutableArray s are equal to each other. Now I am using a NSTimer for that. Here is the code which I used in the method: __block BOOL equal = YES; [Img1Array enumerateObjectsUsingBlock:^(UIImageView *ImageView1, NSUInteger idx, BOOL *stop) { UIImageView *ImageView2 = Img2Array[idx]; if (!CGRectEqualToRect(ImageView1.frame, ImageView2.frame)) { *stop = YES; equal = NO; } }]; if (equal) { NSLog(@"ALL THE FRAMES ARE EQUAL");

How to sort an Array of signed numbers in iOS?

由 ＊爱你＆永不变心＊ 提交于 2019-12-11 20:21:42
问题 This may be a simple question, but i don't know the way of doing sorting of array of signed integer values. My array before sorting, pointsAry (-2,-7,-5,0,-3,2,-1,-4,1,3,-6) After using NSArray * sortedArray = [pointsAry sortedArrayUsingComparator:^(id str1, id str2){ return [(NSString *)str1 compare:(NSString *)str2 options:NSNumericSearch]; }]; Result sortedArray : (-1,-2,-3,-4,-5,-6,-7,0,1,2,3) for signed values the sortedArray format is not correct, so i need like (-7,-6,-5,-4,-3,-2,-1,0

How to specify a label to one specific storyboard?

由 做~自己de王妃 提交于 2019-12-11 20:14:32
问题 Basically I am making an app (a simple game) using storyboards where a question will pop up on the screen and the user has to answer it. They have the option to move onto the next question or to record their response. I have created an NSArray which has a list of questions and I want them to appear in a label randomly (the label will pick one of the questions from the NSArray at random to display). The way I want to do this though is so that each storyboard has a question so once one question

问题 I just had an error, at least different in Xcode.

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1.OC的数组成员是任意的对象指针 与C中的链表结构类似(以nil结尾) 一切的数组操作不能 越界 OC的数组分为不可变数组 NSArray 可变数组 NSMutableArray NSArray * array = [[NSArray alloc]initWithObjects:@"one",@"two",@"three", nil]; NSLog(@"%@",[array objectAtIndex:0]);//通过下标获取数组成员(下标从0开始) NSLog(@"%ld",[array count]);//获取数组有效成员个数 (不包括nil) for (i = 0; i < [array count]; i++) {//遍历数组(C方法) NSLog(@"%@",[array objectAtIndex:i]); } NSLog(@"%@",array);//(OC)查看数组内容(先给array发送description消息，然后给每个成员都发送一个description消息) NSArray * array1 = [[NSArray alloc]initWithArray:array];//创建数组对象 相当于拷贝 NSArray * arry2 = [NSArray arrayWithArray
