Question

我正在尝试初始化UIView。

的子类

我看到以下被抛出的异常：

0 libsystem_kernel.dylib 0x1853e7048 __abort_with_payload + 8
1 libsystem_kernel.dylib 0x1853e1bd8 abort_with_payload_wrapper_internal + 96

13 UIKit 0x18ee8e208 -[UIView initWithFrame:] + 144
14 An App 0x104ca0404 -[myCustomView initWithFrame:] (myCustomView.m:20)

堆栈跟踪中的违规行是myCustomView的初始化函数：self = [super initWithFrame:frame]

上下文代码：

- (instancetype)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
 // do some processing
}
return self;

我无法在本地重现此问题，但我已经收到有关此问题的报告。为什么self = [super initWithFrame:frame]会导致崩溃？我的理解是超级意志最坏的是零，所以我们将返回零。 UIViews的initWithFrame是否存在内部错误？

UIView的超级初始化导致以下崩溃：致命信号EXC_SOFTWARE / SIGABRT
