在我的应用程序中，不要使用autolayout和size类。以编程方式创建所有元素。

计算视图宽度并为每个元素设置框架。这是我的代码。

 UILabel* TitleLbl = [[UILabel alloc] initWithFrame:CGRectMake((self.view.frame.size.width/2)-25,(self.view.frame.size.height/2)-235,100, 50)];
    TitleLbl.text=@"Login";
    TitleLbl.textColor=[UIColor whiteColor];
    TitleLbl.font = [UIFont boldSystemFontOfSize:14.0];
    [self.view addSubview:TitleLbl];


    //NSLog(@"ttttt %@",(self.view.frame.size.height/10));

    UILabel* AccountLbl = [[UILabel alloc] initWithFrame:CGRectMake((self.view.frame.size.width/2)-130,(self.view.frame.size.height/2)-210,350, 50)];
    AccountLbl.text=@"Login or Create Your New Account";
    AccountLbl.textColor=[UIColor whiteColor];
    AccountLbl.font = [UIFont boldSystemFontOfSize:16.0];
    [self.view addSubview:AccountLbl];


    UITextField* UserNameFld = [[UITextField alloc] initWithFrame:CGRectMake(self.view.frame.origin.x+40, (self.view.frame.size.height/2)-175,self.view.frame.size.width-80, 40)];
    UserNameFld.font = [UIFont systemFontOfSize:15];
    UserNameFld.placeholder = @"Username";
    UserNameFld.keyboardType = UIKeyboardTypeDefault;
    NSAttributedString *str = [[NSAttributedString alloc] initWithString:@"Username" attributes:@{ NSForegroundColorAttributeName : [UIColor colorWithRed:244.0f/255.0f green:244.0f/255.0f blue:244.0f/255.0f alpha:1.0] }];
    UserNameFld.attributedPlaceholder = str;
    UserNameFld.delegate = self;
    [self DrawLine: UserNameFld];
    [self.view addSubview:UserNameFld];

    UITextField* PassWorldFld = [[UITextField alloc] initWithFrame:CGRectMake(self.view.frame.origin.x+40, (self.view.frame.size.height/2)-135,self.view.frame.size.width-80, 40)];
    PassWorldFld.font = [UIFont systemFontOfSize:15];
    PassWorldFld.placeholder = @"Password";
    PassWorldFld.keyboardType = UIKeyboardTypeDefault;
     PassWorldFld.secureTextEntry = YES;
    PassWorldFld.delegate = self;
    NSAttributedString *strPassword = [[NSAttributedString alloc] initWithString:@"Password" attributes:@{ NSForegroundColorAttributeName : [UIColor colorWithRed:244.0f/255.0f green:244.0f/255.0f blue:244.0f/255.0f alpha:1.0] }];
    PassWorldFld.attributedPlaceholder = strPassword;
    [self DrawLine: PassWorldFld];
    [self.view addSubview:PassWorldFld];


    UIButton *ForPassBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    //    [ForPassBtn addTarget:self action:@selector(aMethod:)
    //     forControlEvents:UIControlEventTouchUpInside];
    [ForPassBtn setTitle:@"Forgot Password?" forState:UIControlStateNormal];
    ForPassBtn.frame = CGRectMake((self.view.frame.size.width/2), (self.view.frame.size.height/2)-90, (self.view.frame.size.width/2)-40, 20.0);
    ForPassBtn.layer.borderColor = [UIColor whiteColor].CGColor;
    ForPassBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight;
    ForPassBtn.titleLabel.font = [UIFont systemFontOfSize:13.0];
    ForPassBtn.backgroundColor=[UIColor clearColor];
    [self.view addSubview:ForPassBtn];





    UIButton *LoginBtn = [UIButton buttonWithType:UIButtonTypeCustom];
//    [LoginBtn addTarget:self action:@selector(aMethod:)
//     forControlEvents:UIControlEventTouchUpInside];
    [LoginBtn setTitle:@"Login" forState:UIControlStateNormal];
    LoginBtn.frame = CGRectMake(self.view.frame.origin.x+40,(self.view.frame.size.height/2)-65, self.view.frame.size.width-80, 30.0);
    LoginBtn.layer.cornerRadius = 10;
    LoginBtn.layer.borderWidth=1.0f;
    LoginBtn.layer.borderColor = [UIColor whiteColor].CGColor;
    LoginBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
    LoginBtn.titleLabel.font = [UIFont systemFontOfSize:16.0];
    [self.view addSubview:LoginBtn];

如何计算此代码的动态高度。 任何人都可以帮助我。如何计算动态高度。给我任何解决方案。谢谢你。

答案 0 :(得分：2)

在.pch文件中写下

#define iPhoneFactorX ([[UIScreen mainScreen] bounds].size.width*1.00/1080.0)

现在根据屏幕尺寸1080x1920

编写代码

E.g。你想设置一个600 * 400的UIImage 

UIImageView *m1 = [[UIImageView alloc] initWithFrame:CGRectMake(240*iPhoneFactorX, 100*iPhoneFactorX, 600*iPhoneFactorX, 400*iPhoneFactorX)];

以下是我将起点计算为240

的方法 
(1080-600)/2
      ^^^ width of image

这为所有屏幕制作了1个代码......
