自定义UITextField类

#import "WZTextField.h"

@implementation WZTextField

// 修改文本展示区域，一般跟editingRectForBounds一起重写

- (CGRect)textRectForBounds:(CGRect)bounds

{

CGRect inset = CGRectMake(bounds.origin.x+10, bounds.origin.y, bounds.size.width-25, bounds.size.height);//更好理解些

return inset;

}

// 重写来编辑区域，可以改变光标起始位置，以及光标最右到什么地方，placeHolder的位置也会改变

-(CGRect)editingRectForBounds:(CGRect)bounds

{

CGRect inset = CGRectMake(bounds.origin.x+10, bounds.origin.y, bounds.size.width-25, bounds.size.height);//更好理解些

return inset;

}

//修改rightView的位置

- (CGRect) rightViewRectForBounds:(CGRect)bounds {

CGRect textRect = [super rightViewRectForBounds:bounds];

textRect.origin.x -= 10;

return textRect;

}

@end

在控制器中的使用:

- (void)viewDidLoad {

[super viewDidLoad];

WZTextField *tfView = [[WZTextField alloc]initWithFrame:CGRectMake(50, 50, 200, 30)];

//    tfView.backgroundColor = [UIColor grayColor];

//提示文字

tfView.placeholder = @"输入商品";

//圆角

//    tfView.keyboardAppearance = UIKeyboardAppearanceAlert;

//改用layer圆角

tfView.layer.cornerRadius = 12;

tfView.layer.borderWidth = 1;

tfView.layer.borderColor = [UIColor colorWithRed:38/255.0 green:187/255.0 blue:155/255.0 alpha:1.0]

.CGColor;

tfView.tintColor = [UIColor redColor];

tfView.layer.masksToBounds = YES;

//    tfView.text = @"初始化文字";

//右边的x号,点击清除输出 如果设置了rightView 会被覆盖

tfView.clearButtonMode = UITextFieldViewModeWhileEditing;

//.rightView

UIImageView *leftView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];

leftView.image = [UIImage imageNamed:@"search"];

tfView.rightView =leftView;

tfView.rightViewMode = UITextFieldViewModeAlways;

[self.view addSubview:tfView];

}
