If you want to terminate the execution of the block itself, you can simply return from the block, like this:
void (^simpleBlock)(void) = ^{
//block B
//something happened, stop block C from executing...
return;
void (^simpleBlock)(void) = ^{
//block C
};
};
If block C is running already, and you wish to let it know that it should quit as soon as possible, you can do this:
// Set up a flag that is shared among all blocks
__block BOOL blockCShouldStop = NO;
void (^simpleBlock)(void) = ^{
//block A
void (^simpleBlock)(void) = ^{
//block B
//something happened, stop block C from executing...
blockCShouldStop = YES; // <<== Set the flag
return;
void (^simpleBlock)(void) = ^{
//block C
...
if (blockCShouldStop) { // <<== Check the flag
return;
}
};
};
};
