Question

我在UIView中有3个标签，我想将标签位置设置为如下位置： -

Label 1
Label 2
Label 3

现在我用了

label1.frame = CGRectMake(0,0,Width,Height); //for 1st label
label2.frame = CGRectMake(0,label1.frame.size.height,Width,Height); 
//for 2nd label which is correct.

label3.frame = CGRectMake(0,label2.frame.size.height,Width,Height); 
//But when i set like this, position will not show correctly. Any idea??

Answer 1

试试这个。（您必须同时计算按钮height并设置第3个标签y position = label1 + label2 height）

UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(0,0,[UIScreen mainScreen].bounds.size.width,60)]; //for 1st label];
UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(0,label1.frame.size.height,[UIScreen mainScreen].bounds.size.width,60)];
UILabel *label3 = [[UILabel alloc] initWithFrame:CGRectMake(0,label1.frame.size.height + label2.frame.size.height,[UIScreen mainScreen].bounds.size.width,60)];

NSLog(@"Label 1 Frame = %@", NSStringFromCGRect(label1.frame));
NSLog(@"Label 2 Frame = %@", NSStringFromCGRect(label2.frame));
NSLog(@"Label 3 Frame = %@", NSStringFromCGRect(label3.frame));

<强>输出

标签1帧= {{0,0}，{320,60}}
  标签2帧= {{0,60}，{320,60}}
  标签3帧= {{0,120}，{320,60}}

Answer 2

您还应该考虑Y位置

label2.frame = CGRectMake(0,label1.frame.origin.y + label1.frame.size.height,Width,Height); 

label3.frame = CGRectMake(0,label2.frame.origin.y + label2.frame.size.height,Width,Height);

建议：使用Stackview

如何在UILabel位置下设置少量UILabel位置？
