"NSGenericException" - reason: "Access to UITextField‘s _placeholderLabel ivar is prohibited. This is an application bug"
设置TextFiled的默认文字颜色在iOS13 Crash。
[textfield setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"];
查了一下,帖子挺多的,解决方案:
Ivar ivar = class_getInstanceVariable([UITextField class], "_placeholderLabel");
UILabel *placeholderLabel = object_getIvar(textField, ivar);
placeholderLabel.textColor = [UIColor whiteColor];
记得加头文件
#import <objc/runtime.h>
