本文详细介绍了使用SwiftUI进行iOS应用开发的过程，包括创建输入框并设置其样式、颜色及布局。通过具体代码示例，展示了如何实现输入框的自定义外观，如圆角、边框颜色和内边距等，以及如何设置代理和占位符文本。

_myAccount = [[UITextField alloc]init];
    _myAccount.frame =  CGRectMake(0, 0, 200, 100);
    _myAccount.backgroundColor = [UIColor clearColor];
    [_myAccount.layer setCornerRadius:4];
    //设置输入框的颜色
    CGColorRef cgColor = [UIColor grayColor].CGColor;
    _myAccount.layer.borderColor = cgColor;
    //输入框像左空几格 40
    UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0,40, 0)];
    _myAccount.leftView = paddingView;
    _myAccount.leftViewMode = UITextFieldViewModeAlways;  //居中
    _myAccount.layer.borderWidth= 1.0f;
    _myAccount.delegate = self;
    _myAccount.placeholder = @"请输入账号或手机号";
    _myAccount.font = [UIFont systemFontOfSize:17];
    _myAccount.clearButtonMode = UITextFieldViewModeWhileEditing;
    _myAccount.contentVerticalAlignment = UIControlContentHorizontalAlignmentCenter;
    [_myLoginView addSubview:_myAccount];
