您需要正确设置框架.

int count=20;

for(int i = 0; i < [items count]; i++){
    UILabel *label =  [[UILabel alloc] initWithFrame: CGRectMake(0,count,0,0)];
    label.text = @"text"; //etc...
    [label sizeToFit]; // resize the width and height to fit the text
    count+=20;

    [_scroll addSubview:label];
}
