UITextField 文本与清除按钮重叠
我在视图中添加一个文本字段，如下所示：
UITextField* tf_email = [[UITextField alloc] initWithFrame:CGRectMake((320-btnImage1.size.width)/2, 170, 175, 35)];
[tf_email setBackgroundColor:[UIColor clearColor]];
[tf_email setBorderStyle:UITextBorderStyleRoundedRect];
[tf_email setClearButtonMode:UITextFieldViewModeWhileEditing];
[tf_email setReturnKeyType:UIReturnKeyDone];
[tf_email setAutocapitalizationType:UITextAutocapitalizationTypeNone];
[tf_email setEnablesReturnKeyAutomatically:NO];
[tf_email setDelegate:self];
[tf_email setOpaque:YES];
tf_email.tag=1;
tf_email.font = TTSTYLEVAR(font);
tf_email.layer.cornerRadius = 10;
tf_email.keyboardType = UIKeyboardTypeEmailAddress;
[tf_email setAutocorrectionType:UITextAutocorrectionTypeNo];
tf_email.placeholder = @"[email protected]";
[self.view addSubview:tf_email];
当我在该字段中输入长文本时，文本和清除按钮重叠。有谁知道如何解决这个问题？
I am adding a textfield to my view like this:
UITextField* tf_email = [[UITextField alloc] initWithFrame:CGRectMake((320-btnImage1.size.width)/2, 170, 175, 35)];
[tf_email setBackgroundColor:[UIColor clearColor]];
[tf_email setBorderStyle:UITextBorderStyleRoundedRect];
[tf_email setClearButtonMode:UITextFieldViewModeWhileEditing];
[tf_email setReturnKeyType:UIReturnKeyDone];
[tf_email setAutocapitalizationType:UITextAutocapitalizationTypeNone];
[tf_email setEnablesReturnKeyAutomatically:NO];
[tf_email setDelegate:self];
[tf_email setOpaque:YES];
tf_email.tag=1;
tf_email.font = TTSTYLEVAR(font);
tf_email.layer.cornerRadius = 10;
tf_email.keyboardType = UIKeyboardTypeEmailAddress;
[tf_email setAutocorrectionType:UITextAutocorrectionTypeNo];
tf_email.placeholder = @"[email protected]";
[self.view addSubview:tf_email];
When I enter long text in to this field, the text and the clear button overlaps. Does any one know how to fix this?

创建
UITextField的子类并重写下面给出的方法，干杯！
Create a subclass of
UITextFieldand override the methods given below,Cheers !!!
我想到了问题所在。在另一个文件中，我为 UITextField 定义了一个类别。该类别指定文本区域非常靠近左右边框。这导致了重叠。
经验教训：定义类别时，我们应该使用单独的文件，以便可以轻松检测到修改。
I figured what the issue was. In another file, I had a category defined for UITextField. This category, specified the text area to be very close to the left and right border. That was causing the overlap.
Lesson learnt: When defining categories, we should use separate files so that the modifications are easily detectable.
@Augustine PA，我认为更好的方法是调用 super 并修改结果，如下所示：
@Augustine P A, I think a better approach is to call the super and modify the result like this:
添加文本字段后，调用
[button BringSubviewToFront:self.view];After adding the text field, call
[button bringSubviewToFront:self.view];
